Follower baffle plate for centrifugal casting by hot mold method

Abstract

The invention relates to a baffle plate for centrifugal casting by hot mold method, which comprises a fixed plate, sliding small shafts and a follower plate, 2-6 sliding small shafts are fixed on the end surface of the fixed plate, sliding holes which correspond to the sliding small shafts are arranged on the follower plate, the sliding holes are in clearance fit with the sliding small shafts, the follower plate is fixed with the fixed plate through the sliding small shafts, and fine aluminum line cliques are wound at the tail ends of the sliding small shafts for compressing the follower plate and the fixed plate. The baffle plate can effectively solve the quality problems of cracks and the like caused by resistance when a pipe shrinks during the pouring by the hot mold method, and realize high molding qualification rate.

Description

technical field [0001] The invention relates to a baffle plate for thermal mold centrifugal casting. Background technique [0002] The process of hot mold pipe forming is generally as follows: liquid steel is poured into the mold, the molten steel is cooled in the mold, and gradually turns into a solid pipe, and the solid pipe gradually cools down. When adopting thermal mold method to centrifugally cast pipes, baffles must be fixed at both ends of the pipe mold in advance to ensure smooth molding of the poured pipes. At present, the baffles used in hot mold casting are generally single-layer baffles. This kind of baffle is fixed on the mold by fixing pins, bolt fastening, etc., and is fixed during the hot mold casting. During the transition process of molten steel in the mold from liquid phase to solid phase and solid state cooling process, greater stress will be generated. Since the baffle is fixed, it will hinder the shrinkage of the pipe, which will easily cause quality...
