Method and apparatus for cleaning the surface of a twin roll thin strip continuous casting roll

摘要

A method for cleaning a surface of a twin-roller continuous thin strip casting roller, each casting roller of the twin-roller continuous thin strip casting machine using two brush rollers arranged at the top and bottom for cleaning the surface thereof, wherein a rotational direction of at least one brush roller is the same as the casting roller, a linear speed of the casting roller is constant and greater than a rotational speed of the casting roller, and a roller surface cleaning device controls a distance or a pressure between the brush rollers and the casting roller by means of a position control device fixed on a casting roller bearing seat, and controls the flattening amount to be within 1-10 times of the average pit depth of the casting roller face after brushed, so as to ensure cleaning efficiency of the roller surface. During the twin-roller thin strip continuous casting process, the present invention can improve cleaning efficiency of the continuous thin strip casting roller, make the coefficient of thermal conductivity of the roller surface to be uniform and increase cast strip quality.
