Abstract
The invention discloses a centrifugal liquid steel-making slag remover and a slag removing method, and belongs to the technical field of steel-making equipment. In the slag remover, a slag collecting cover, a centrifugal rake and a slag containing disk ascend or descend by driving a lead screw to rotate, until the centrifugal rake is inserted into the slag. A blade continuously takes away the slag by driving the centrifugal rake to rotate at a high speed; meanwhile, the slag on the blade is thrown to an inner lateral wall of the slag collecting cover under the centrifugal force; then the slag reached the inner lateral wall of the slag collecting cover can drop into the slag containing disk under the gravitational force. The slag containing disk is turned over for putting the slag inside the slag containing disk into a slag tank, and thereby finishing the slag removing work. Aiming at the disadvantages of the existing slag removing equipment, a novel slag removing manner (i.e., removing the slag by means of the centrifugal rake rotating at the high speed) is employed after the original design concept is abandoned. With less floor area and more flexible operation, the disclosed slag remover can effectively shorten the slag removing time and remove the slag more thoroughly.
