The present invention relates to a heat treatment method and a heat treatment apparatus in which a strip material is continuously inserted into a heat treatment furnace, and a jet air stream is blown onto the strip material during the heat treatment. The heat treatment can be performed in a state where the heat transfer coefficient between the material and the jet airflow is extremely high, and the material can be heat treated in a short time and with a short furnace length while saving energy. At the same time, it also prevents damage to the material. It is an object of the present invention to provide a heat treatment method and a heat treatment apparatus that allow the above-mentioned heat treatment to be performed in a state where the heat treatment is performed. The drawings showing the embodiments of the present application will be described below. Reference numeral 1 denotes a band-shaped material made of copper, copper alloy, or other various materials. 2 is a feeding device;
3 and 4 are direction changing rolls. Next, heating device 5
I will explain about it. 6 is a furnace shell, and 7 is a refractory heat insulating material, which constitute the furnace body. 8, 8 is a plenum chamber, the inside of which is filled with gas for heat treatment. 9 is a nozzle plate that constitutes the surface of the plenum chamber 8 that faces the strip material 1;
A number of jet nozzles are provided, each of which directs the gas within the chamber 8 towards the strip of material. In addition, these nozzles are arranged in large numbers in the part indicated by A in FIG. The blowout area of the airflow 10 is made to vary in size.
Moreover, instead of changing the number of nozzles, the blowing area of the jet air stream may be changed by changing the blowing area of the nozzle itself. The above-mentioned plenum chamber 8 has a structure as shown in FIG.
2, it is press-fitted into the chamber 8 as shown by the arrow, and is blown out from a nozzle provided on the nozzle plate 9. 13 is a seal roll,
It is designed to seal the inside of the furnace. 14 is a chimney, and 15 is an exhaust damper. Next, in the cooling device 16, 17 is a plenum chamber;
Reference numeral 8 denotes a nozzle plate, which has the same configuration as that in the heating device 5 as shown in FIG.
As a result, the air is press-fitted into the chamber 17 as shown by the arrow, and is blown out from the nozzle of the nozzle plate 18. Next, 19 is a throat, which is provided so as to seal the inside of the cooling device 16. 20
is a coolant tank filled with a coolant such as water.
21 is a date roll, 22 is a drying device, 23 is a direction changing roll, and 24 is a feeding device. In the structure described above, the strip material 1 supplied from a well-known supply device not shown is fed into the heating device 5 via the feeding device 2 and direction changing rolls 3 and 4 as shown in FIG. . This heating device 5
The strip-shaped material 1 fed into the heating area A is rapidly heated (e.g.
650° to 750°C), and depending on the strength of the jet airflow, the jet air travels in a wavy manner, bending at certain points as shown in FIG. The thus heated strip-shaped material 1 is also soaked in the soaking area B while being made into a corrugated shape. This strip material 1 is then sent from the heating device 5 to the cooling device 16 . In this cooling device 16 as well as in the heating device 5, the strip material 1 is cooled while being bent into a wave shape (for example, to 170 to 185° C.). The cooled strip material 1 then passes through the throat 19 into the cooling liquid tank 20 where it is further cooled (e.g.
65°C), is dried in a dryer 22, and further sent to the next process (for example, a winding process) by a feeding device 24. Note that the waveform (wave pitch, height, etc.) of the strip material 1 in the heating device 5 and cooling device 16 is determined by the thickness of the strip material 1 and the heating temperature or cooling temperature. Next, a specific example of various amounts when heat treatment is performed as described above is as follows. When the strip material is brass (65/35 brass) (1) Dimensions of the strip material: 0.3 mm (thickness) x 630 mm (width) (2) Feed speed: 60 m/min (3) Furnace temperature: 650 to 800°C (4) Ejection pressure and ejection flow rate of jet air flow to the strip-shaped material: The length of the heating zone is 16 m, and it is divided into four in the longitudinal direction (the direction of movement of the strip-shaped material), and a hot air circulation fan is installed in each division. Two circulation fans are arranged side by side in the direction of movement of the strip material, so that a crest or trough with a length of 2 m is formed by each circulation fan. Capacity of one hot air circulation fan: (a) Air volume: 200 to 600m 3 /min (more than 600m 3 /min is fine, but efficiency will decrease) (b) Pressure (blowout pressure from nozzle): 50 to 500mm
Aq (at 20℃ air) (c) The respective pressures on the high-pressure side and low-pressure side surfaces of the strip-shaped material when jet airflow is blown onto the strip-shaped material (this pressure is set to about 3:1, for example) ) High pressure side: 15Kg/m 2 Low pressure side: 5Kg/m 2 Above is an example for the above material, but these values vary depending on the material of the strip material, dimensions, and the degree of heat treatment required ( It is changed depending on the physical properties such as bending strength and tensile strength of the heat-treated material. For example, if the material becomes soft (or thin), the feed speed may be increased or It is advisable to take corresponding measures such as lowering the blowing pressure of the jet air flow or reducing its flow rate. Furthermore, when the temperature inside the furnace is increased or the length of the furnace is changed, it is preferable to change the blowing pressure and flow rate of the jet air flow accordingly. Next, Table 1 compares the various heat treatment apparatuses described above with conventional apparatuses. The heat transfer coefficient in this example is calculated from the Friedman-Mueller equation, which is known as an equation for calculating the coefficient when the jet air blows against the strip-shaped material as described above. Also, conventional example 1
In this method, a plurality of nozzles arranged along the direction of movement of the strip material are each provided with a thin guide plate, and a convex surface is provided between the two nozzles, and gas is introduced between the convex surface and the nozzles. Those with a structure that can be pulled out (for example, those shown in Japanese Patent Publication No. 43-20439)
The results are shown below (the heat transfer coefficient was calculated from Keller's equation, which is known as a formula for calculating coefficients in such a configuration). Furthermore, Conventional Example 2 has a structure in which gas is blown onto the strip-shaped material from a number of chambers, and the gas is extracted from between the chambers (for example, the structure shown in Japanese Patent Publication No. 47-3686). 1), the results calculated in the same manner as in Conventional Example 1 are shown.

Next, FIG. 4 showing a different example of the plenum chamber 8e will be described. In this figure, the plenum chamber 8e is divided into a plurality of high pressure chambers 8a and low pressure chambers 8b, and the pressure of the gas blown out from the nozzle is directed in the direction of movement of the strip material 1e, alternating the height on the front and back sides of the strip material 1e. This shows an example in which the material 1e is bent into a wave shape. In this case, the blowout area of the jet air flow 10e may be constant over the entire nozzle plate 9e, or may be different as in the case of the nozzle plate 9 described above. It should be noted that the same reference numerals as those in the previous figure are appended with an alphanumeric letter "e" for parts that are functionally the same or equivalent to those in the previous figure, and redundant explanations are omitted. (Also, in the following figure, the same idea is given with an alphanumeric f and redundant explanation will be omitted.) Next, in FIG. In the case shown by the two-dot chain line, the nozzle plate 9f of the strip material 1f
This figure shows an example in which the portion C adjacent to the portion C receives a large blowing force of the jet air flow 10f and bends as shown by the solid line. As described above, in this invention, the strip material 1
When a jet air stream for heat treatment is applied to the material while it is being moved, the entire front and back surfaces of the material are covered with a center plane locus (indicated by reference numeral 41 in Fig. 1) of the movement locus of the waveform of the material. ) from the direction perpendicular to the strip material (the direction shown by the arrow 42), and the jet air flow that has been blown onto the strip material is pulled out from the side in the width direction of the strip material (pulling). Mouth 44
45) so that a gas flow in the direction opposite to the direction of the jet air flow (in the direction of arrow 43) does not occur from the strip material. (This is to prevent blank areas that cannot be sprayed), the strip material 1 is coated on most of the front and back surfaces (the entire surface of section X or Y necessary to bring about a predetermined temperature change of the strip material 1).
100% of the material is exposed to the jet air flow, and the heat transfer coefficient between the jet air flow and the strip material is extremely high (approximately double that of conventional materials). As a result, the time required to change the temperature of the strip material 1 to a predetermined temperature can be reduced to a fraction of that of the conventional method. The length of the section required to bring about the change can be reduced to a fraction of that of the conventional method, thus reducing the cost of the heat treatment equipment and requiring only a fraction of the space (a fraction of the time). It is highly beneficial as it not only provides energy saving benefits, but also produces energy saving effects. Furthermore, in the present invention, since the strength of the jet airflow 10 blown onto the strip-shaped material is different from front to back alternately in the moving direction of the strip-shaped material 1, when the strip-shaped material 1 is advanced, it is as if it were supported by rollers. It has the characteristic of being able to advance while bending in a wave-like manner at a fixed position as if it were a metal strip. This has the advantage that the material 1 can be prevented from coming into contact with surrounding furnace hardware and the like and becoming scratched. Moreover, during this process, the strip material can be made into a corrugated shape as described above, so the bending of the strip material in the width direction can be controlled at all times. It also has the advantage of preventing scratches from occurring due to the edges coming into contact with hardware in the furnace. Furthermore, in the present invention, as described above, the strip material 1
Even if the material is made to advance while being bent into a waveform, the operation is performed by varying the strength of the jet airflow as described above, so that the entire surface of both the front and back of the above-mentioned strip material is There is no effect on the fact that a high heat transfer coefficient can be obtained by blowing the jet air stream onto the air, and there is also the effect that the above-mentioned high degree of usefulness can be maintained as it is. Furthermore, in the present invention, by widening the blowing area of the jet air flow 10, the jet air flow 10
If the force exerted on the strip material 1 is increased to make it wave-shaped, the jet air stream 10 is strongly blown (a large heat treatment effect can be obtained).
This has the effect that the strip-shaped material 1 can be heat-treated more evenly and uniformly at certain locations. Furthermore, if the jet nozzle is connected to a high pressure chamber and the pressure of the jet air flow blown out from the nozzle is increased to make the strip material into a corrugated shape, the pressure of the jet nozzle in the high pressure chamber can be changed to create a corrugated shape for various strip materials. It has the feature that it can be bent into the most suitable bending state.

A feeding device capable of moving the strip-shaped material in its longitudinal direction, and a jet air flow for heat treatment on each surface of the strip-shaped material so as to be opposed to each other on both the front and back sides of the movement locus of the strip-shaped material. The jet nozzle is provided with a plurality of jet nozzles arranged so as to spray jet air, and each of the jet nozzles blows jet air in a direction perpendicular to the central plane locus of the moving locus of the strip material moving in a waveform state as described below. Furthermore, these jet nozzles are arranged alternately on the front and back sides in the traveling direction of the strip-shaped material so that the strip-shaped material can be made to advance while waving at a certain position due to the difference in the blowing strength of the jet air flow against the strip-shaped material. On the other hand, at the lateral positions in the width direction of the strip-shaped material in the moving process, the jet airflow that has blown onto the strip-shaped material is directed to the sides in the width direction of the strip-shaped material. A pull-out opening is provided so that the material can be pulled out, and airflow from the surface of the material strip in a direction opposite to the direction perpendicular to the center plane locus is not generated. A heat treatment apparatus characterized in that the jet air stream is blown in a direction perpendicular to the locus of the center plane to heat-treat the strip-shaped material. 2 A feeding device capable of moving the strip-shaped material in its longitudinal direction, and a plenum chamber disposed to face both the front and back sides of the movement locus of the strip-shaped material, and each of the above-mentioned plenum chambers The bar is formed such that high-pressure chambers and low-pressure chambers are formed alternately along the traveling direction of the strip material, and high-pressure chambers and low-pressure chambers are formed opposite to each other between both plenum chambers. Furthermore, in the high-pressure chamber and low-pressure chamber formed by the above-mentioned partitions, jet nozzles communicating with the chamber are respectively arranged on the surfaces facing the moving strip material, and these nozzles , the jet air flow for heat treatment can be applied to the strip material in a direction perpendicular to the central plane locus in the movement locus of the strip material moving in a waveform state as described below; A jet nozzle provided in the high-pressure chamber is provided with a pull-out port at a lateral position in the width direction of the strip-shaped material so as to draw out the jet airflow that has blown onto the strip-shaped material laterally in the width direction of the strip-shaped material. The jet air flow blown out from the jet nozzle provided in the low-pressure chamber has a different blowing strength against the strip-shaped material, so that the strip-shaped material is made to advance in a waveform at a certain position, and the jet air flow is blown from the surface of the strip-shaped material to the center of the strip-shaped material. The jet airflow is blown in a direction perpendicular to the center plane locus on each of the front and back surfaces of the strip-shaped material, without producing an airflow in the opposite direction to the direction perpendicular to the plane locus. A heat treatment apparatus characterized in that it is capable of heat treating a strip-shaped material.
