A rapid sequential solidification device for high manganese steel broken wall castings

Abstract

The invention discloses a fast progressive solidification device for a high manganese steel broken wall casting. The fast progressive solidification device comprises an upper sand box, a sand mold, a base and a sand core, wherein the bottom of the upper sand box is fixedly arranged on the upper surface of a rapid cooling block; the bottom of the rapid cooling block is fixedly arranged on the upper surface of the base; the upper sand box is filled with sand and is molded to form the sand mold; the sand core and a cold type inner hole are positioned through a core head to form an inner cavity structure of the broken wall; a pouring channel and a dead head are formed in the sand mold; the upper end of the pouring channel extends to be communicated with the outside; the pouring channel extends downward to reach the sand core; an end opening runs through a molding part of the broken wall; the dead head runs through the molding part of the broken wall and the outside; the inner wall of the rapid cooling block corresponds to the outer wall of an important work part of the molding part of the broken wall; a water passing groove is formed in a cold forming manner; and the outer wall of the water passing groove directly faces the lower end part of the molding part of the broken wall. According to the fast progressive solidification device for the high manganese steel broken wall casting, the condition that a cast structure which is fine in crystal particle, free of a sinkhole, dispersed, and free of slag defects is obtained by the broken wall in the casting process can be ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a rapid and sequential solidification device for high manganese steel broken wall castings. Background technique [0002] Cone crusher is a kind of mechanical equipment for metallurgy, chemical industry, building materials, hydropower, mining, transportation construction and other industrial departments to crush or finely crush various ores or rocks with different hardness. It has reliable structure, stable operation, high production efficiency, It is characterized by convenient adjustment and uniform particle size. It works as figure 1 As shown, wherein: label 1' is the rolling socket wall, label 2' is the crushing wall, label 3' is the bevel gear, and label 4' is the eccentric swing mechanism. [0003] In the crusher, the rolling mortar wall and the crushing wall are two key components in the operation process of the equipment. When the crusher is wor...

AI Technical Summary

Problems solved by technology

Therefore, the working part of the casting may have no shrinkage cavity and shrinkage defects, but due to the coarse grains and many inclusions, the impact resistance and wear resistance of the casting must be poor during work, which is not a good process plan

[0007] From the above analysis, it can be seen that it is difficult to obtain high-quality high manganese steel broken wall castings by simple sand casting.
