Method and Device for Cleaning a Surface of a Twin-Roller Continuous Thin Strip Casting Roller

摘要

A method for cleaning a surface of a twin-roller thin-belt continuous casting roller, wherein each casting roller of the twin-roller thin-belt continuous casting machine comprises two brush rollers in an upper and lower arrangement for cleaning the surface thereof, wherein a rotational direction of at least one brush roller is as same as a casting roller, and the linear speed of the casting roller is constant and greater than its rotational speed; and a roller surface cleaning device controls the distance or the pressure between the brush rollers and the casting roller by a position control device fixed on a casting roller bearing seat, and it controls the flattening amount in 1-10 times of the average pit depth on the casting roller face after being brushed, so as to ensure cleaning efficiency. In a process of twin-roller thin-belt continuous casting, the present invention can improve the cleaning efficiency of the thin-belt continuous casting roller, and make the coefficient of thermal conductivity of the roller surface more uniform and increase the quality of belt.
