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...

Effect of carburizing defect on quality of steel casting

Lost Foam Casting (LFC) has been recognized by the foundry industry for its unique technological advantages. Many developed countries have applied EPC technology to the production of various products on a large scale. However, the carburization defect of EPC casting has seriously restricted the development of EPC process in...
