Abstract

The invention relates to a crystallizer cavity-shaped structure, and belongs to the field of metal continuous casting. The cavity-shaped structure is a pipe defined by four copper plates, two of the copper plates which are oppositely arranged are wide panels, and the other two copper plates which are oppositely arranged are narrow panels; the wide panels are curved panels; the plate surface of thecurved plates change in a continuous straightening curve along the casting direction of the crystallizer; and the plate surface of the curved plates change in a piecewise function curve along the horizontal direction of the crystallizer. By applying the continuous straightening curve, the curvature of the crystallizer at the inlet of the crystallizer is not zero, within the limited length of thecrystallizer, the overall strain of a casting blank shell is small and constant, the strain rate is low, and the casting blank quality is improved; the problem that the strain rate of a casting blankshell of a traditional thin slab crystallizer in the crystallizer is too high is solved, the crack defect of the surface of a casting blank is overcome, abrasion of the casting blank to a crystallizercopper plate coating is reduced, and the service life of the crystallizer is prolonged.

Description

technical field [0001] The invention belongs to the field of metal continuous casting, and in particular relates to a crystallizer cavity structure. Background technique [0002] The thin slab continuous casting and rolling process has the advantages of simplified process, short production process, less equipment, energy saving, high yield, etc., and can face the market more flexibly, and has become the key investment target of steel production companies in recent years. The main difference between thin slab continuous casting and rolling technology and conventional continuous casting technology lies in the mold. As we all know, in order to solve the problem of molten steel flow in the gap between the mold and the nozzle, the mold is designed in a funnel shape with a large top and a small bottom, but this design makes the billet shell subject to additional stress in the mold and is prone to crack defects. Therefore, the cavity shape curve of the mold is particularly importa...
