Abstract

The invention relates to a one-button type continuous casting slab four-corner hot-state cutting device and method, and belongs to the technical field of continuous casting slab trimming equipment and methods in the metallurgical industry. According to the technical scheme, a fuel gas cutting part is installed on a casting blank supporting, positioning and moving part, an electric appliance automatic control part is connected with the fuel gas cutting part, billet centering placement, guide wheel positioning and opening degree adjustment, cutting gun positioning adjustment and cutting gun flame adjustment are conducted, and finally the one-key cutting process is started. The steel billet of the variety steel with the edge cracks generated through cold rolling is subjected to corner cutting treatment before rolling. The method has the beneficial effects that the source of edge cracks is eliminated before rolling, and the function of a chamfering crystallizer is replaced.

Description

technical field [0001] The invention relates to a one-button continuous casting slab four-corner thermal cutting device and method, belonging to the technical field of continuous casting slab trimming equipment and methods in the metallurgical industry. Background technique [0002] The edge crack defects of individual steel grades of hot-rolled coils (such as MR series steel grades) after entering the cold-rolling unit have always been the focus of quality research in the hot-rolling industry. After years of hard work in the industry, basically two technical route. One of the technical routes is to choose a chamfering crystallizer, and the cross-section of the finished billet is octagonal. This kind of slab enters the hot coil rolled out by hot rolling and then enters the cold rolling defect problem, which can basically be solved. The disadvantage is that the chamfering crystallizer is expensive and has high operating costs. Contents of the invention [0003] The object...
