Model casting process method of steel sections or steel balls

Abstract

The invention relates to a model casting process method of steel sections or steel balls. The process method adopts a lost foam casting process. By adopting the process method disclosed by the invention, metallographic structures of the produced steel balls or steel sections are punctiform, pellet-shaped or broken-net-shaped, and thus the wear resistance of the steel sections or the steel balls can be increased by 2 times compared with that of sand mold casting; and in addition, the model casting process method can ensure that the cast small steel balls cannot be out of circularity, further can be used for reducing the enterprise cost, and is beneficial for large-scale production of the steel sections or the steel balls.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting model process method for steel segments or steel balls. Background technique [0002] In the field of modern machinery manufacturing, the foundry industry is playing an increasingly important role. For ordinary small steel balls and small steel sections, sand casting is often used, but the small steel balls and small steel sections cast by sand molds often have defects such as non-wear resistance and easy loss of roundness, which makes engineering applications, every year A large number of unqualified steel balls and steel sections must be eliminated, which increases the cost of the enterprise and is not conducive to large-scale production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a casting model process method for steel segments or steel balls. cost, which in turn facilitates large-scale production of steel ...
