Horizontal continuous casting crystallizer for casting copper plate billet

Abstract

The invention discloses a horizontal continuous casting crystallizer for casting a copper plate billet, and relates to the technical field of metallurgical equipment. According to the horizontal continuous casting crystallizer, a graphite die combination, an upper water-cooled copper sleeve and a lower water-cooled copper sleeve are mounted in a groove of a U-shaped lower steel fixing frame, and meanwhile, a lower cooling water inlet and a lower cooling water outlet are formed in the upper plane, flush with the upper plane of an upper steel fixing frame, of the lower steel fixing frame, so that the segregation degree of the copper plate billet is effectively reduced through the graphite die combination in the casting process, a crystallization line of the copper plate billet is smooth, hole shrinkage, porosity, cracks and other defects are avoided, the microstructure is uniform, the quality is stable, the technical problems that the defects of the copper plate billet are increased, a crystallizer is poor in performance stability, errors of the size of the plate billet are seriously large, and disassembly and assembly are complex due to the fact that the traditional crystallizer adopts a distance block are solved, the structure is simple, and manufacturing is convenient.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a horizontal continuous casting crystallizer for casting copper slabs. Background technique [0002] With the rapid development of the automobile industry, especially new energy vehicles in China, the market demand for copper strip products used in the manufacture of automotive connector terminals is increasing, especially tin, which has excellent mechanical properties, wear resistance and corrosion resistance. Phosphor bronze. The crystallizer is the key equipment in the horizontal continuous casting production line. The mold for horizontal continuous casting of copper and copper alloy slabs is placed at the exit of the heating furnace. When the liquid copper water flows through the crystallizer, the cooling liquid in the cooling channel will The heat of the copper liquid is taken away, causing it to solidify into a solid and form a copper piece. [0003] The h...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide a horizontal continuous casting crystallizer for casting copper slabs, by installing the graphite mold combination, the upper water-cooled copper sleeve and the lower water-cooled copper sleeve under the concave shape, the steel is fixed In the groove of the frame, at the same time, the lower cooling water inlet and the lower cooling water outlet are set on the upper plane of the lower steel fixed frame that is flush with the upper plane of the upper steel fixed frame, which solves the problem of traditional crystallizers. The technical problems of enlarged copper slab defects, poor crystallizer performance stability, serious out-of-tolerance slab size and complicated disassembly and assembly caused by the distance block
