Roller cooling device and method for rolling composite metal material

Abstract

The invention discloses a roller cooling device and method for rolling a composite metal material, belongs to the technical field of cold rolling mills, and aims to solve the problems that the temperature of a roller is not high, a large amount of sprayed water causes certain waste, the pressure of a water pump is increased due to the pressure of a spray head during spraying, the service life of the water pump is influenced, and the service life of the water pump is influenced. The water pump cannot adjust the pressure and the flow speed of the water flow; by closing a valve, under the action of a driving assembly, a movable plate reciprocates at the top of the shell and extrudes one group of extrusion blocks, so that gas in the water tank enters one row of second cavities, gas in the second cavities enters a first cavity through a second communicating pipe, and the gas in the second cavities enters the first cavity through a second communicating pipe; according to the water spraying device, water enters the arc-shaped plate through the pipeline and finally penetrates through the first cavity to be sprayed out of the first spring, under the movement of the first fixing plate, the atomizing heads in each row spray water intermittently, and water resources are saved.

Description

technical field [0001] The present invention relates to the technical field of cold rolling mills, in particular to a roll cooling device and a cooling method for rolling composite metal materials. Background technique [0002] The roll is the main working part and tool for continuous plastic deformation of the metal on the rolling mill. 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 shape. The roll neck is installed in the bearing, and the rolling force is transmitted to the frame through the bearing seat and the pressing device. The shaft head of the transmission end is connected with the gear seat through the connecting shaft to transmit the rotating torque of the motor. For the rolls, the rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill stand. ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a roll cooling device and cooling method for rolling composite metal materials, which solves the problems caused by a large amount of water sprayed down when the roll temperature is not high during actual cooling in the background technology. Waste, and the traditional spraying mostly uses water pumps to drive the water source. When spraying, the pressure of the spray head will increase the pressure of the water pump, which will affect the life of the water pump, and the model of the water pump in the actual operation process is fixed, making it impossible to adjust the pressure of its water flow and its flow rate
