Application test of φ 150 mm multiphase wear resistant cast steel ball

1.Characteristics of wear resistant steel ball The composite wear-resistant casting steel ball has excellent comprehensive properties such as high strength, strong toughness and fatigue resistance. The steel ball is made of manganese, silicon and nickel as phase change elements. After compound inoculation and special heat treatment process, the high...

φ 150 mm multiphase wear resistant cast steel ball

The steel ball used in ball mill can be divided into casting ball and forging ball. Generally, the diameter of casting ball is less than 120mm, which is used in ball mill; large diameter mill or semi autogenous mill requires larger diameter of steel ball, which is basically forged...

Analysis of tensile properties of lost foam steel casting

The properties of tensile samples were tested by a universal testing machine controlled by microcomputer, and the tensile strength and lower yield strength of each sampling part were tested. With the different sampling locations, the tensile strength and yield strength of cast steel castings produced by the same foamed...

Mechanism of carburizing defect in lost foam steel casting

The filling process of lost foam casting is the replacement process of metal liquid and foam pattern. Because the pouring temperature of molten steel is high (above 1550 C), the gasification and cracking of foam pattern are relatively sufficient, resulting in a large amount of elemental carbon. Carbon diffuses...
