Forging process of mining support parts

Forging is a method of machining metal mechanical parts or blanks under impact or pressure by means of tools or dies. Compared with casting, it can eliminate internal defects, improve or eliminate internal component segregation, and obtain uniform and fine macrostructure and macrostructure, with high toughness, reasonable fiber structure,...
