本発明は焼結機の稼動中に発生する片寄り走行
を防止する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for preventing lopsided running that occurs during operation of a sintering machine.
（従来の技術）
焼結機は給排鉱側に設けたスプロケツトを介し

り得ない等の欠点を有している。 This long sintering machine creates a temperature difference on both sides of the machine length depending on the operating conditions or equipment conditions including the surrounding area, resulting in uneven running due to thermal expansion. Otherwise, wear and tear on the rails and the like will incur a large repair cost, and furthermore, leakage of suction air will occur, resulting in economic losses in terms of sintering productivity, quality, energy costs, etc. Therefore, in order to prevent the sintering machine from running lopsidedly due to this heat, for example,
As in Japanese Patent No. 37269, it has been proposed to provide a pressurized cold air supply device on the pallet travel path on both sides of the sintering machine length to forcibly cool the pallet and prevent uneven travel.
However, in this apparatus for blowing pressurized cold air, a large amount of cost is required for the production of pressurized air and injection equipment, resulting in high running costs. Moreover, since cold air is blown into hot air, the cooling effect is poor and it takes a long time to suppress uneven running, making it impossible to quickly normalize it.

行防止方法の提供にある。(Problems to be Solved by the Invention) The present invention eliminates the need for pressurized cold air and its injection equipment, which are disadvantageous in suppressing lopsided driving due to the blowing of compressed cold air as described above, and can be easily and quickly resolved. An object of the present invention is to provide a method for preventing lopsided running, which uses heat around the sintering machine itself to normalize skewing caused by mechanical or operational factors inherent in the sintering machine.

し得た。 The cause of uneven running of the sintering machine is due to the difference in the sintering temperature of the left and right sintering raw materials within the pallet, the difference in expansion of the pallet due to the difference in the sintering speed, or it occurs from the wind box, wind leg, exhaust gas duct, etc. This is due to temperature differences caused by rising hot air currents. On the other hand, mechanically, it is caused by differences in the level and misalignment of the rails, differences in the fit of pallet wheels, etc. Regarding the above-mentioned rising hot air current, as shown in Fig. 3, air flowing into the building 1 from outside as indicated by the arrow rises due to the heat of the pallet 2, wind leg 3, and main duct 4, which are the exhaust gas routes for sintering. The temperature rises and becomes an upward thermal airflow, and this upward thermal airflow also causes the above-mentioned differences due to the layout of the entire building, the installation of the sintering machine in the north-south direction, seasonal winds in winter, etc. Driving sideways occurs. The present inventors have discovered that the atmospheric temperature (rising hot air current) near the pallet side and rail portion due to the rising hot air flow is as high as 60 to 90°C when no means are taken;
And the temperature difference between both sides of the sintering machine is 10~30℃ due to one-sided running.
In addition to this, it was found that there was no wear and tear on the sintering machine itself as long as the ambient temperature was below the above.

常化できることにある。 Therefore, the present invention is to control the rising hot air flow in order to adjust the ambient temperature on both sides of the sintering machine since the ambient temperature near the pallets is high.
As mentioned above, it is possible to easily normalize uneven running caused by other operational conditions such as firing temperature, sintering speed difference, mechanical factors, etc., including atmospheric temperature as described above.

止し、操業の安定化が図れる。 In this way, by controlling the temperature on both sides of the sintering machine by controlling the temperature on both sides of the sintering machine by utilizing the rising hot air current, which is originally the main cause of uneven running, it is possible to quickly correct uneven running by correcting the temperature difference caused by other factors. In addition to normalizing the operation, it also reliably prevents wear and tear on the axles, rails, seals, etc. of the sintering machine, and stabilizes the operation.

The lower part of this sintering machine A consists of a wind leg 3 and a main duct 4, and is covered with an appropriate heat insulator. It is isolated from the outside air by. Further, a wheel 11 is rotatably fixed to the pallet side portion 2a via an axle 10, and is mounted so as to be able to run on a rail 13 on an external support 12.

This hot air flow creates a temperature difference of 10 to 30° C. between both sides (side portions 2a) of the sintering machine A and in the machine length direction, and the sintering machine A begins to move toward either side.

When this detected value exceeds a preset target value, the hot air flow rising between the bulkhead 7 and the external column 12 of the sintering machine A and the pallet side 2a is divided into a plurality of parts in the longitudinal direction, and the axial A shielding plate 16 rotatably mounted on a shaft 15 is opened as shown by the arrow in the figure, or conversely closed to control the rising hot air flow. By controlling this rising hot air flow, the ambient temperature near the pallet side portion 2a is adjusted. Any part may be used as long as it is a part where the shielding plate 16 is attached or a part lower than the rail 13 of the sintering machine A that can shut off the hot air flow. Further, the shielding plate 16 may be operated by fixing a wire rope at one end and opening and closing by tightening and loosening the wire rope, or by using an electric motor, a hydraulic cylinder, etc.

ツト側近の雰囲気温度は約20℃の降下を見た。 First, the operation was performed with all the shielding plates for rising hot air currents on both sides fully open. As a result, the sintering machine began to shift from approximately the middle to the rear, and the amount was 16 mm. After this, all of the shielding plates on the one-sided side were closed from the middle to the rear. At the same time as the shielding plate was closed, the ambient temperature near the pallet dropped by approximately 20°C.

害も解消された。 In addition, in another example, the axle and the wheel were offset by about 10 mm due to poor fitting balance, but by partially blocking the shielding plate, almost normal running was maintained. The frequency of replacement and repair has been drastically reduced, and the production disruption caused by the suspension of sintering equipment has also been eliminated.
