Description

Technical Field

[0001] The utility model relates to a modular multi-functional steel plate cooling bench, belonging to the technical field of extra-thick plate production in the metallurgical industry. Background Technique

[0002] The steel plates produced by medium and heavy plate steel enterprises are characterized by heavy tonnage and large size. The heat treatment cooling methods adopted generally include natural cooling, air cooling, water cooling, oil cooling, quenching and other methods. For some medium-carbon steel grades with large thickness, due to their composition and performance requirements, stronger cooling methods cannot be adopted. They must be placed in the air and cooled by conventional fans. However, since the steel plate is stationary, the heat at the lower surface is easy to accumulate, resulting in uneven heat dissipation between the upper and lower surfaces, insufficient cooling capacity, and large differences in overall performance. In addition, for steel plates above 200 mm, due to their too large tonnage, the roller quenching machine method cannot be used for cooling, and it is not easy to control the plate shape and performance when using a quenching tank. In order to meet the cooling requirements of medium-carbon steel plates with large thickness and avoid quality problems caused by uneven heat dissipation temperature difference and insufficient cooling capacity between the upper and lower surfaces of conventional air cooling, it is urgent to develop a cooling device that reduces the uneven cooling of the upper and lower surfaces of medium-carbon steel thick plates, so as to improve the uniformity of the performance of the upper and lower surfaces of the steel plate and improve the product quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a modular multi-functional steel plate cooling bench, which can effectively reduce the problem of uneven cooling of the upper and lower surfaces of heat-treated steel plates in the air, further strengthen its cooling effect, and solve the problems existing in the background technique.

[0005] A modular multi-functional steel plate cooling bench includes a base bottom plate, a support shelf, side plates, an overflow partition plate, a spray pipe, a return water pipe and a water inlet pipe. Four side plates are respectively vertically fixed on the base bottom plate. A rectangular cooling water tank body is formed between the four side plates and the base bottom plate. An overflow partition plate is arranged in the rectangular cooling water tank body. The overflow partition plate divides the rectangular cooling water tank body into two areas: an inlet water cooling area and a return water area. A spray pipe and several support shelves for placing heat-treated steel plates are arranged in the inlet water cooling area. The spray pipe in the inlet water cooling area is connected to the water inlet pipe, and the return water area is connected to the return water pipe.

[0006] The overflow partition plate in the rectangular cooling water tank body is close to one of the four side plates, so that the inlet water cooling area is larger than the return water area.

[0007] The height of the overflow partition plate in the rectangular cooling water tank body is less than the height of the four side plates.

[0008] A plurality of support shelves for placing heat-treated steel plates in the water inlet cooling area are respectively vertically fixed on the foundation bottom plate, and their heights are greater than the heights of the four side plates.

[0009] The spray pipe in the water inlet cooling area is provided with water spray holes spraying towards the water inlet cooling area.

[0010] Reinforcing plates are provided between the support shelves, side plates, overflow partitions and the foundation bottom plate.

[0011] A blower facing the heat-treated steel plate is provided outside the rectangular cooling water tank body.
