Heavy special-shaped continuous casting billet descaling system

Abstract

The invention discloses a heavy special-shaped continuous casting billet descaling system which comprises a centering detection mechanism arranged on a continuous casting billet roller way conveying line, and an upper descaling mechanism, a blowing mechanism, a lower descaling mechanism and a side descaling mechanism which are sequentially arranged on the periphery of a continuous casting billet behind the centering detection mechanism. According to the system, the centering detection mechanism is directly connected with a production line in a butt joint mode, and synchronous operation of the descaling system and the production line is achieved; and meanwhile the upper descaling mechanism, the lower descaling mechanism and the side descaling mechanism are arranged to remove oxide scales on the surfaces of heavy special-shaped continuous casting billets on the continuous casting machine roller way conveying line one by one, dislocation installation of the descaling mechanisms and on-line automatic adjustment of the descaling mechanisms are ingeniously utilized, and the purpose of removing oxide scales on the surfaces of casting blanks with misaligned positions and different heights and widths is achieved. Better conditions are created for surface quality defect detection of a special-shaped continuous casting billet body; and the surface quality of the special-shaped continuous casting billet can better meet the raw material requirements of steel rolling.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a descaling system for heavy-duty special-shaped continuous casting billets. Background technique [0002] The heavy-duty special-shaped continuous casting billet is a kind of billet, generally in the shape of the letter H. The steel billet coming out of the continuous casting machine will have a layer of scale on the surface due to high temperature oxidation, some of which float on the surface of the billet, and some are closely attached to the surface of the billet. Due to reasons such as process, equipment and operation, some surface defects often appear on the body surface of the continuous casting billet. Since the surface of the continuous casting slab is covered with a layer of iron oxide scale, the surface quality defects on the continuous casting slab body are not easy to be detected. In order to improve the accuracy of surface quality testing instruments,...
