Description

Technical Field

[0001] The utility model relates to the field of rolling mills, in particular to a rolling mill roll cooling mechanism. Background Art

[0002] The roll is the main working component and tool on the rolling mill that causes continuous plastic deformation of the metal. The roll is mainly composed of three parts: the roll body, the roll neck and the shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The transmission end shaft head is connected to the gear seat through the connecting shaft, which transmits the rotational torque of the motor to the roll. The rolls can be arranged in the rolling mill frame in the form of two rolls, three rolls, four rolls or multiple rolls.

[0003] Patent publication number CN217665419U describes a cooling device for a rolling mill. The patent mentions that after a sprinkler sprays water onto the upper and lower rollers for cooling, the remaining water passes through a filter and falls into a water collection tank. The filter removes particulate matter generated during mill operation, keeping the water in the tank free of impurities and preventing clogging of the water pump. However, in actual use, this device still suffers from the following drawbacks: the filter needs to be regularly disassembled and manually cleaned, resulting in high maintenance costs.
