Abstract

The invention discloses a supporting roller air cooling device, and belongs to the field of heat treatment. The supporting roll air cooling device aims to realize uniform cooling and reduce the overall hardness deviation of a workpiece. The supporting roll air cooling device comprises a tire rolling device and a blower device, wherein the rolling tire device comprises a base and rolling tires supported on the base, the rolling tires are movably connected with the base around the axis of the rolling tire, two groups of the rolling tires are arranged in parallel, a gap is formed between the two groups of rolling tires, a lifting area for lifting a supporting roll is formed by the two groups of rolling tires, and a driving device for driving the rolling tires to rotate is arranged; the blower device is arranged on the sides of the rolling tires in the rotating axial direction of the rolling tires, the blower device comprises a support, air supply pipelines and N groups of nozzles which are vertically distributed along the support, the nozzles are installed on the support, one ends of the nozzles communicate with the air supply pipelines, and the other ends of the nozzles directly face the lifting area. According to the supporting roll air cooling device, through rotary blower cooling, the cooling uniformity is ensured, so that the hardness uniformity of the supporting roll is ensured, and the cooling speed can be accelerated through rotary cooling.

Description

technical field [0001] The invention belongs to the field of heat treatment, in particular to an air cooling device for backup rolls. Background technique [0002] The back-up roll is an important part in the rolling mill. It is used to support the work roll or the intermediate roll to prevent the work roll from being deflected and deformed, which will affect the output and quality of the product. Therefore, the hardness and hardness of the roll body and roll neck surface of the back-up roll should be uniform. sexual demands. [0003] The back-up rolls are normalized in a desktop heat treatment furnace to meet the hardness requirements of the roll neck. After the high temperature in the heat treatment furnace is over, the back-up rolls are air-cooled out of the furnace. There are two traditional normalizing air cooling methods for backup rolls: [0004] One is to place the support roller horizontally on the shim iron for natural air cooling. This cooling method is greatly ...
