Description of the Invention (1) (Technical Field of the Invention) The present invention is a heat treatment in which a gas jet is sprayed on a steel sheet for heating, cooling or drying. Device. (Conventional technology) There has been a heat treatment device that sprays a gas jet on a steel sheet for heating, cooling, or drying, but it has a low thermal conductivity α for heat conduction using a gas as a heat medium. Therefore, it cannot satisfy metallurgy. High heating speed and cooling speed function required. _For example, in the above-mentioned Japanese Patent Publication No. 2-16375 published by the inventor, "Although the cooling device for steel sheet using gas jet is mentioned", the setting range of its thermal conductivity is 400kcal / m2Hr ° C. This thermal conductivity is only achieved when the thickness of the steel sheet is 0. 6mm. A cooling rate of only 100 C / sec is achieved. When the thickness of the sheet is i_0mni, a cooling rate of approximately 60 ° C / sec is obtained. Therefore, when higher thermal conductivity is required, methods such as Xingkun cooling method in contact with water-cooled roller solids or gas-water cooling method in which gas is mixed with water must be used. However, it is difficult to obtain uniform solid contact with the light cooling method, which causes problems such as uneven temperature of the steel sheet and deterioration of the shape of the steel sheet. On the other hand, since gas-water cooling uses water, it causes problems such as oxidation of dissolved oxygen on the surface of the steel sheet, and it is necessary to perform pickling again after heat treatment. (Explanation of the invention) In the heat treatment equipment for heating and cooling the steel sheet by spraying a gas jet, it is only necessary to increase the flow rate of the spray gas to the steel sheet in order to improve the thermal conductivity of the steel sheet. According to the results of the experiment, it is known that the heat transfer rate is increased in proportion to the gas flow rate. However, the increase of the flow velocity of the gas and the body will cause the nozzle.

V. The heat exchanger of the invention (6). Fig. 23 (i) shows the relationship between the power ratio of the blower and the gas injection temperature when cooling the steel strip in the heat treatment device using a gas jet. (Best Mode for Carrying Out the Invention) The present invention will be described in detail as follows. And when solving problems, try to start from various aspects. The present invention seeks a solution from the viewpoints of the nozzle form 'gas exhaust, effective gas jet length ratio, and jet gas temperature, etc., and is explained in order as follows. The first is the opening of the nozzle, which is compared with various tests for the most appropriate nozzle diameter and nozzle pitch. As a result, even if the gas injection flow rate is increased, the present inventors can recognize that the nozzle diameter and the nozzle pitch defined in the above-mentioned proposed Japanese Patent Publication No. 2_16375 are the most effective ones. Although the test range of the present invention and the test range of Japanese Patent Publication No. 2_16375 are shown in the figure i, if there is no problem with the gas exhaust gas described later, it can be known that the area with a thermal conductivity of 40kcal / m2Hrt or more, the air volume density and The relationship of thermal conductivity is also on its approximate extension line. In addition, the means of raising the thermal conductivity of the 4 gas ejected from the nozzle is to reduce the thermal conductivity of the stagnation point formed when the ejected gas touches the object, and it is generally known to promote the I-flow at this point. For example, in Shikai Sho 61_5a report, as shown in Fig. 7, it is not described that a resistance plate 3 or a spiral 6 is provided as a nozzle turbulence promoting body. However, as shown in the Si- ·% report, the cross-shaped resistance plate 3 must have a nozzle length that can accommodate 2 to 3 resistance plates. It is difficult to manufacture most nozzles in the industry. 6The same will apply to the Chinese Standard (CNS) Secrets (plus Canadian meals) for the standard of air quality ---- (Please read the precautions on the back before filling this page)

Description of the invention (7) It is not an effective device for the body to rotate and diverge with centrifugal force. As described above, the 'turbulent flow intensity gradually weakens at the center of the airflow, and thus rises. The turbulence at the center of the nozzle affects the effective increase of the thermal conductivity. According to the present invention, as shown in FIG. 2, a method for promoting turbulence at the center portion of an air flow that is easy to implement in the present invention is provided with a resist 2 or a resist plate 3 at the center of the front end of the nozzle. Thereby, as shown in 3 (a) and (b), a full-range turbulent flow 5 is formed at the rear of the resist 2 or the resist plate 3, and a turbulent flow can be generated in the central area of the air flow 4. In addition, the cross-sectional shape of the resistance body 2 may be formed in a polygonal shape other than a circular shape. The second method is to review the smooth exhaust method for the gas emitted from the nozzle as follows. As described above, in order to increase the thermal conductivity, it is only necessary to increase the velocity of the gas sprayed on the steel sheet. That is, it is only necessary to increase the amount of the spray gas. However, when this exhaust gas is insufficient, the injected gas will temporarily stay, and the interference with the newly injected gas will begin to occur, which will not improve the phenomenon of heat transfer rate as expected. In Fig. 1, the solid line is an example when the exhaust is good, and the broken line is an example when the exhaust is poor. When the exhaust is poor, the increase in the thermal conductivity will passivate when the air volume density is higher than a certain density. Therefore, in order to effectively improve the thermal conductivity, the smooth exhaust of the air jet is an important issue. The present invention obtains two solutions to this problem. As a result of investigating the air flow behind the conflicting steel sheets, it can be known that when the gas jets ejected from the nozzles collide, they flow along the steel sheet and collide with the jets ejected from the adjacent nozzles and flow away from the steel sheet. It can be seen that the rising airflow between the nozzles is generated at the oblique line portion in FIG. 14, and the flow rate of 20% to 40% of the jet flow from the nozzle is increased. ， This paper size applies Chinese National Standard (CNS) A4 specification (210X297).

Description of the invention (8) Therefore, the present invention can ensure that the gas jet from the nozzle conflicts with the gas jet from the adjacent nozzle A gap of a gas exhaust opening having a sufficient area of the updraft is formed. Fig. U shows the relationship between the opening area S1 and the nozzle opening area S2. As shown in FIG. 13 (a), the gas ejected from the nozzle 丨 is ejected after the conflicting steel sheet 7, and then flows upward on the steel sheet 7 to collide with the gas jet from the adjacent nozzle. This updraft is shown in Figure 13 (a). When the air is not forcedly exhausted, it cannot be fully exhausted because it flows to the end in the width direction of the steel sheet. mixing. As a result, the temperature of the gas jet from the jet 1 rises during cooling and decreases during heating, so that the desired effect cannot be obtained. In addition, because the gas stays between the steel sheet 7 and the gas jet 8, the flow of the plate-like gas flowing on the steel sheet 7 is slowed, and at the same time, the cooling ability of the gas jet from the jet 1 to collide with the surrounding edges is reduced. The device of the present invention is provided with an opening portion 10 between the gas nozzles 8 shown in Fig. 13 (b), and the upward air flow is separated from the opening portion 10. Therefore, the gas jet ejected from the nozzle 1 can reach the surface of the steel sheet 7 without being affected by the gas at the time of rising and reversing, which can cool or heat the steel sheet 7. In addition, since no gas is trapped between the steel sheet 7 and the gas shower head 8, a smooth gas flow can be formed along the steel sheet 7, and a decrease in gas cooling or heating ability can be mitigated. -Figure 15 shows the structure around the nozzle of the heat treatment equipment of the present invention.

The front end of the nozzle is from the front end of the gas jet = a large protruding nozzle 'When the gas is discharged from the opening 10, the flow of the jet from the nozzle-the part will not conflict with the steel sheet, which can prevent it Exhaust directly. 、 This paper ruler ~ ~ ^ 擗 (⑽) (Read the note on the back ^ W | h before filling out this page) Order 11 Printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs

Description of the invention (ι〇) 'Find the relationship between the air volume density and the thermal conductivity ratio. The thermal conductivity ratio refers to the ratio of the thermal conductivity based on a certain thermal conductivity. This relationship is shown in Fig. 18 "When the nozzle projection height h of Fig. 18 is 200 mm, it can be known that the heat transfer ratio is increased by approximately the proportion of the increase in the air volume density, and the ejected gas is not retained and discharged. When the protruding height of the nozzle is low, the increase in the thermal conductivity ratio of a certain air volume density is relatively slow, so that the ejected gas stays and interferes with the newly ejected gas from the nozzle. It can also be seen that this inclination starts when the protruding height h is lower and the air volume density is lower. Based on these relationships, the relationship between the air volume density Wm3 / min m2 and the necessary nozzle protrusion height hmm can be obtained from the following formula. W / 4 ^ h In addition, it is self-evident that the wind measurement W is calculated based on the maximum air volume density possible on the device in order to perform effective functions in all equipment performance areas. In addition, the nozzle projection height h is obtained from the minimum height described above. However, if the length is increased more than necessary, the nozzle pressure loss and the equipment manufacturing cost must be increased. Therefore, it must be selected near the necessary minimum height. The review of the effective gas injection length ratio is as follows. Generally, the cooling rate is defined by Δt / T ° C / sec by the cooling temperature difference Δ and the time Tsec required for cooling during cooling. The heating rate is also defined during heating. This metallurgy is an important cooling speed 'heating speed', and has been improved on the equipment to increase these speeds. In the heat treatment device of the spray gas jet, in order to increase the heating speed or the cooling speed to make the distance between the nozzle and the steel sheet close, the velocity of the gas sprayed from the nozzle is prevented from decaying as much as possible.

However, due to operational reasons, the push rollers 16 and 17 are equipped with a light delay device for free advancement and retraction relative to the steel sheet. Alas, it is necessary to have a light insertion space and not be able to spray gas on this part, forming a field that is thermally and physically wasted. In addition, due to the delay of the heating rate and cooling rate of the forming part due to the existence of these spaces, it is not conducive to metallurgical operations / metallurgical important heating rates, cooling rate generally means average acceleration or average cooling rate 'When increasing the value, you can effectively obtain a high-efficiency gas injection space, and at the same time reduce the insertion space as much as possible. Order the consumer cooperation of the Central Bureau of Standards of the Ministry of Economic Affairs Du Yinfan Figure 19, starting from gas injection to Length to completion. The ratio of the actual sprayed gas length is called the effective gas sprayed length ratio. In the past, the effective cooling length ratio in the continuous annealing equipment of steel sheets was around 80%. Therefore, the present invention also reviews the heating or cooling in the insertion space of the pressing roller. The pushing roller insertion space shown in Fig. 19 is roughly divided into the insertion roller side and the non-roller side with respect to the steel sheet 7. Without roller side system A gas injection device extension 22 is provided as shown in Fig. 20, thereby forming a gas injection space. There is a roller pressing device that can push the pressing roller 16'17 and the pressing roller forward and backward, so it is difficult to install a gas injection device, and even if it is installed, it is not easy to access the steel sheet, which has a bad effect. Therefore, the present invention will examine the heating or cooling of the roller by pressing or heating it. This can form a very small space for heating or cooling, which is related to the invalid area.

Description of the invention ~~~ Or the roller can be inserted into the space with the medium Μ Λ & q ”丨 ″, the heating and cooling can increase the average heating speed, or cooling speed. Finally, the most appropriate temperature of the ejected gas when cooling the fourth steel sheet is reviewed as follows. The general tendency is that once the temperature of the injection gas decreases, the required power of the blower also decreases, but at a certain temperature, the temperature of the refrigerant and the injection gas used in the heat exchanger will be reduced due to the decrease of the temperature of the injection gas. Due to the temperature difference, although the pressure loss of the heat exchanger is increased, the temperature of the injection gas no longer continues to decrease and instead the power required for the blower rises. The results of a detailed review of the temperature of the injection gas, the most appropriate injection temperature, that is, the point at which the power nozzle of the blower is formed is in the range of approximately 60 ° c to 20 ° (rc). The temperature of the sheet, the temperature of the steel sheet on the output side, the temperature of the refrigerant used, etc. vary. In particular, this time, the results of a detailed investigation of the high thermal conductivity area were compared with the conventional low thermal conductivity area. The most appropriate point is when the temperature of the jet gas is low. Increasing the iffit degree of the spray gas to form a temperature that can affect the power of the blower. (Figures 2 and 3) Therefore, the solutions for effectively reducing the temperature of the spray gas are reviewed below. The non-oxidizing ambient gas is circulated and sprayed on the steel sheet. In the cooling heat treatment device, the method of cooling the surrounding air by ambient gas is generally a heat exchanger using water as the refrigerant. In the past, the heat exchanger must also be installed on the inlet side of the blower considering the temperature protection of the blower. As mentioned above, although only It is necessary to increase the capacity of the heat exchanger to reduce the temperature of the injection gas, but once the refrigerant temperature and When the temperature difference of the gas is reduced, the heat exchange effect is not good. Although the pressure loss of the gas passing through the heat exchanger is increased, the temperature of the ejected gas does not decrease. The result is shown in Figure 23.

Description of the invention (13) When it falls, it will instead increase the power of the blower. Therefore, in the present invention, the 'injection gas' is aimed at increasing the temperature when the blower is boosted, and a heat exchanger is provided on the output side of the blower. That is, instead of adding a heat exchanger on the output side of the blower, it is possible to obtain a larger temperature difference between the gas temperature and the temperature of the refrigerant than to increase the heat exchanger on the input side, thereby improving the heat exchange rate. In this way, when the same thermal conductivity () and gas injection temperature are obtained, it can be achieved with a lower blower power than in the past. In particular, when the gas injection speed of the steel sheet is increased to increase the boosting amount of the blower, the increase in the gas temperature of the blower can have a significant effect. EXAMPLES Examples of the resistors mounted on the nozzles will be described in order. As shown in Fig. 2 (a) '⑻, the cooling high-temperature plate was investigated for the heat transfer characteristics generated by the gas jet from the nozzle with the resist 2 and the resist 3 provided. Using air as the cooling medium, the nozzle diameter is 105 mm, the air velocity from the nozzle is 150 m / s, and the distance from the front end of the nozzle to the object to be cooled is 50 mm. The cooling hot plate was examined for the characteristics of a nozzle provided with this resistor at the front end. The results are shown in Fig. 4, and the thermal conductivity is increased just below the center of the nozzle. The ratio of the projected area of the resist to the cross-sectional area of the nozzle in the cooling conditions is shown in Fig. 5 for the resistance system. Only 3 / of the sectional area of the nozzle is required. The above technical film area can show the effect of pre-boosting heat conduction. In addition, when the projected area is more than 12%, the pressure loss at the front end of the nozzle caused by the installation of the resist is increased, which is not good for increasing the power of the blower. ) (Please read the note on the back before filling this page)

In addition, when the thickness of the resistance plate is 3% or more, the pressure of the gas is increased due to the length of the nozzle shaft in comparison with the above-mentioned resistance body.

However, incomplete exhaust gas will be formed at this time, so it is necessary to adjust the protrusion height h of the nozzle in accordance with the area of the opening portion. Using the apparatus of the present invention shown in Figs. 9 and 10, cooling was performed using a gas jet of a steel strip 1 having a thickness of 0 mm using a mixed gas of nitrogen and hydrogen as a cooling medium. The cooling nozzle projecting length h & 20 mm at this time. Fig. 12 is a certain blower power, which shows the thermal conductivity ratio when the ratio of the opening area to the opening area of the nozzle is changed. Table 1 shows the nozzle diameter and nozzle pitch. In Fig. 12, the cooling effect of the gas jet on the steel sheet is evaluated by the average thermal conductivity in the width direction of the steel sheet. When the ratio of the opening area to the opening area of the nozzle is 0, 34, and 17.3, the results of the comparative example are shown. Here, the area ratio 0 means that the opening is completely closed.

Description of the invention (π) After the gas system conflicts with the steel sheet 7, it flows along the steel sheet 7 and conflicts with the gas ejected from the adjacent nozzle, which is opposite to the gas protruding from the nozzle, that is, from the steel sheet 7. It flows toward the gas shower head 8. Subsequently, the gas collides with the gas shower head and flows in the direction of the gas shower head, and the exhaust gas is discharged from the area held by the gas shower head 8 and the steel sheet 7. At this time, when the density of the air volume of the gas is small, the gas flow along the gas jet is flowing in the area of the nozzle protruding height h, but once the air volume bifurcation is increased, the steel sheet 7 in this area to the front end of the nozzle The realm is filled with post-conflict gas. When formed as described above, the gas that conflicts with the steel sheet will be entrained again by the gas ejected from the nozzle. For example, when cooling the steel sheet, although the ejected gas is cooled, the steel sheet is surrounded by the conflicting high-temperature gas, so that the temperature of the gas that conflicts with the steel sheet rises and reduces its cooling effect. In addition, if the gas nozzle adopts a certain nozzle height of 11 or more, uniform gas exhaust can be performed, but it is also possible to appropriately divide the gas nozzle and promote the exhaust between the gas nozzles. In particular, when the width of the steel sheet is wide or the length of the gas nozzle is large, the gas nozzle can be effectively divided when the size of the gas nozzle is large. The third is a related embodiment showing an improvement in the ratio of effective gas jet length. Fig. 19 shows a conventional steel sheet heat treatment apparatus using a gas jet. The steel sheet 7 is close to the nozzle 1 to improve the gas jet efficiency. However, in order to avoid the contact between the nozzle and the steel sheet caused by the vibration and warpage of the plate, the left and right pressing rollers 16 and the right pressing roller Π are alternately pressed ^ but Since the gas is not sprayed into the left pressing roller insertion space 2 3 and the right pressing roller insertion space 2 4 of these pressing roller parts, the cooling or heating is performed in the interval of L1, and the heating or cooling is included therein.

Status of gas injection length ratio β Fig. 20 illustrates an embodiment of the present invention. In Fig. 20, a gas injection device extension portion 22 is provided on the opposite side of the steel sheet 7 of the wishing person, and the gas injection is shortened until completion. Length L2 Figures 19 and 20 are the same as the actual injection gas length L2, but when comparing L1 and L2, the length is shorter than L2 to form a high effective gas injection length ratio. Set the moving speed of steel sheet 7 to Vm / sec. Time, the time required for heating or cooling is shortened by (l 1 _ L2) / V seconds. The heating speed or cooling speed is also increased relative to this amount. In addition, when the present invention is applied to an actual steel sheet continuous annealing treatment equipment The effective gas injection length ratio can be increased from 82% to 90%. Also, as mentioned above, heating or cooling can be improved by heating or cooling of the pressing roller to increase the heating or cooling effect. However, as mentioned above, The equipment for heating or cooling the roller makes it generally difficult to make uniform contact between the roller and the steel sheet, resulting in disadvantages such as uneven temperature of the steel sheet. However, according to the experiment 'Generally, the diameter of the roller that pushes the roller is less than φ300ηΐΓη, which is relatively small compared to the general When the diameter of the roll used for heating or cooling the roll is φ10000ηΐΓη, a large steel sheet is pressed to the pressure of the roll (hereinafter, the surface pressure), and there is no uneven heating and cooling of the steel sheet. Fig. 21 is a cross-sectional view of the pressing roller part. In addition, the left pressing roller system has the same equipment configuration, so only the right pressing roller will be described as a representative. In this example, the water-cooled roller is used as the pushing device.

Fig. 22 (a) shows a conventional embodiment of a heat treatment apparatus in which a circulating non-oxidizing surrounding gas jet is sprayed on a steel sheet and cooled. In Fig. 22 (a), 7 is a steel sheet to be cooled, and the inside of the heat treatment chamber wall of 13 is cooled in a surrounding gas of a non-oxidizing gas (not shown). 9 In order to attract the non-oxidizing gas in the heat treatment chamber and increase the pressure of the blower, the surrounding gas in the heat treatment chamber is sucked through the duct 34. A heat exchanger 35 for cooling the surrounding gas is provided in the middle of the duct, and the cooled gas is boosted by the blower 9. After the pressure rise, the surrounding gas system is again introduced into the heat treatment chamber through the conduit 34, and the steel sheet 7 is sprayed by the nozzle 8 and the nozzle 1 to rapidly cool the steel sheet. The position of this heat exchanger is conventionally used to protect the blower 9 in the heat, so that the surrounding gas in the heat treatment chamber is cooled in the heat exchanger and sucked by the blower. That is, a heat exchanger is arranged on the upstream side of the blower. In the past, because the paper size of the steel sheet was in accordance with the Chinese National Standard (CNS) A4 specification (21 × 297 mm) 22 A7 Β7 · V. Description of the invention (2G) Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 404982 Cooling heat transfer The setting range of the rate is relatively low, so the ejection flow velocity from the front end of the nozzle is not very low, and the blower does not require the desired amount. Therefore, the temperature rise of the gas around the blower is small, which will cause practical problems. However, once the thermal conductivity of the steel sheet is increased, the jet flow velocity at the front end of the nozzle must be increased and a high boost amount of the blower must be required. As a result, the temperature rise after the boost cannot be ignored. As shown in FIG. 22 (b), after the blower 9, the heat exchanger 3 is installed on the downstream side to obtain good cooling efficiency. In other words, when the temperature of the surrounding gas is reduced by a certain amount, the heat exchanger efficiency of Fig. 22 (1)) can be made smaller than (a). As a result, the pressure loss of the heat exchanger can be reduced, and the blower of the heat treatment device can also be reduced. Capacity. Furthermore, although the heat exchanger is installed before and after the blower in Fig. 22 (b), if there is no problem with the heat resistance of the blower, the heat exchanger on the upstream side can be removed and it can be installed only on the downstream side. (Application fields in the industry) The present invention is a heat treatment device that can spray a gas jet on a steel sheet to heat, cool and dry the steel sheet. The turbulent flow of the central part of the gas jet can be used to promote Tinan's thermal conductivity. The gas sprayed on the steel sheet can be exhausted to prevent interference with the newly sprayed gas and improve the thermal conductivity. Also, the present invention is a heat treatment device that can spray a gas jet on a steel sheet for heating, cooling and drying of the steel sheet, and can shorten the idle floor of the left and right roll insertion space, that is, the unheated, cooled and dried part of the steel sheet.
