BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing deformation of a Buckstay, which acts as a pillar of a coke oven, from deformation from the high heat generated during the dry distillation of the coke oven. The space between the tie rods is provided with a plurality of temperature control pipes and a cover of a perforated plate to surround them, thereby extending the life of the coke oven by blocking heat flowing from the coke oven to the foil stay. The present invention relates to a box stay thermostat and deformation preventing device of a coke oven for improving the quality of a coke product.

In general, the coke oven 100 is supported by holding the refractory forming the coke oven while maintaining the tension of 268 box stays 130, 134 tie rods 140, 804 springs, The combustion chambers 120 are formed between the plurality of carbonization chambers 110 and between them by the refractory material. The coke oven 100 charges the coal in the interior of each carbonization chamber 110, and carbonizes them, and the carbonization chamber 110 from the combustion chamber 120 disposed between the high-temperature silver carbonization chamber 110. Is provided to the side.

As shown in FIGS. 1 to 3, the coke oven 100 is equipped with a foil stay 130 on both sides thereof, and the # 1 and 2 springs on the upper and lower portions of the respective foil stays 130.

Accordingly, these springs 135a, 135b and 137 apply a respective tension to the coke oven 100 through the tie rods 140 disposed laterally through the coke oven 100 to carbonize the chamber. The separation of the silica lead, which is the refractory formed in the 110 and the combustion chamber 120, is prevented, and smooth shrinkage expansion is achieved even when shrinkage expansion due to the change of season.

That is, such a coke oven 100 is equipped with a plurality of tie rods 140 made of round rods to cross both sides thereof, each end of these tie rods 140 as shown in the planar section in FIG. Likewise, the H-shaped structural beams 145 are installed vertically, and the tie rods 140 pass through the structural beams 145 and the combustion chambers 120 and are integrally coupled to each other. A plurality of springs 135a, 135b, 137 and fastening nuts 160 are interposed at both ends thereof, so that the H-shaped structural beam 145 is provided with the elastic force of the springs 135a, 135b, 137, and Through the tie rods 140 is to support the coke oven (100) structurally stable.

As such, when the support structures of the foil stay 130 are bent and the warpage phenomenon occurs, the coke support equipment does not have a constant tension, and thus, the shape deformation of the carbonization chamber 110 and the combustion chamber 120 occurs. In this process, the silica brick forming the inner wall may also be the cause of the phenomenon.

In addition, the tie rod 140 is cut by the load of the biased springs 135a, 135b, and 137 provided at both ends of the plurality of tie rods 140 supporting the carbonization chamber 110 and the combustion chamber 120. A phenomenon occurs that may have a fatal adverse effect on the furnace body of the coke oven (100).

In addition, if a total of 8576 springs 135a, 135b and 137 mounted on the box stay 130 are generated as a factor of inhibiting the contraction and expansion of a normal furnace due to the loss of tension ability due to high heat, In connection with the coke oven 100 has a problem that the phenomenon that various kinds of forbidden to be mounted on the edge of the coke oven is released

The present invention is to solve the above conventional problems, the purpose is to circulate the cold air in the atmosphere between the outer wall of the coke oven and the foil stay when the temperature of the coke oven rises to discharge the high heat to the outside of the carbonization chamber and box By minimizing the temperature change of the table, it is possible to prevent deformation of the coke oven structure and box stay, preventing equipment damage, and to improve the coke oven's box stay automatic temperature control and deformation prevention device.
