Description

Roll cooling device for aluminum casting and rolling mill

technical field

The utility model relates to the technical field related to casting and rolling, in particular to a roll cooling device for aluminum casting and rolling mills.

Background technique

Ingotless rolling refers to the process of directly "rolling" liquid metal into semi-finished products or finished products, referred to as continuous casting and rolling, while aluminum casting and rolling requires the use of aluminum casting and rolling mills in the working process. The main working parts and tools for deformation. 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 metal. It has a smooth cylindrical or grooved surface. The roll The 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, and the rotational torque of the motor is transmitted to the roll. The roll is in the rolling mill frame. It can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls. The rolls mainly act as a crystallizer for liquid metal and also have a rolling effect. It is different from the continuous casting-rolling process. The latter is the continuous casting of metal Solidification in the crystallizer of the machine, and the deformation process is completed in the rolling mill. After the aluminum casting rolling mill works for a long time, in order to ensure that the roll is not affected by high temperature, reduce the wear of the roll, prevent the rough surface of the roll and suppress the thermal crown of the roll, cooling is required. The device cools down the roll.
