A funnel-type crystallizer copper plate mold for continuous casting of thin slabs

Abstract

The invention discloses a funnel-shaped crystallizer copper plate mould of a continuous casting sheet billet. The funnel-shaped crystallizer copper plate mould comprises a cooling water tank, a cooling water tank surface, inlaid strips, a rib plate and a water through hole in the rib plate, wherein the front side of the cooling water tank is a funnel-shaped working face, and the back surface of the cooling water tank has a cooling function; the inlaid strips are inserted into the cooling water tank to control the section dimension of the cooling water tank; the rib plate is arranged between the cooling water tank; the inlaid strips are connected with two positioning mechanisms arranged on the upper part and the lower part of the cooling water tank surface; the inlaid strips and the cooling water tank form a water passing sectional area and are fixed through the positioning mechanisms; the cooling water tank sectional area of the high-temperature area of the copper plate mould is smaller than the area of the middle lower part; a distance between the working face of the high-temperature area of the copper plate mould and the bottom surface of the cooling water tank of the copper plate is smaller than the distance of the middle lower part; a distance between the center of the water hole of the high-temperature area of the copper plate mould and the working face of the copper plate mould is smaller than the distance of the middle lower part; therefore, the defect that water flow on a regulation screw position disorders since the area of the water tank is occupied because the regulation screw is adopted to regulate the inlaid strips is overcome, the service life of the copper plate mould is prolonged, and meanwhile, the quality of a continuous casting billet is stably improved.

Description

Technical field [0001] The invention relates to the technical field of production and use of a continuous casting thin slab copper plate mold, in particular to a continuous casting thin slab funnel type mold copper plate mold. Background technique [0002] Because the continuous casting thin slab has the process characteristics of continuous casting and rolling, its production efficiency is high, and it has attracted more attention. Because of the thinness of the thin slab, the intrusive nozzle cannot be normally inserted into the copper plate mold. Therefore, the nozzle part of the mold wide copper plate mold Using the flared funnel that expands outwards, the overall thickness of the continuous casting thin slab copper plate mold is also thickened. Because the thickness of the copper plate mold is inconsistent in various parts, and the working surface of the copper plate mold is required to be relatively consistent with the cooling position, the water tank depth is produced Inco...
