Pilger Mill in GIDC, Vapi, Meraj Engineering | ID: 2014037173

Pilger mill is a metalworking process in which metal is disfigured by passing it through rollers at a temperature below its recrystallization temperature. Pilger milling increases the yield strength and hardness of a metal by introducing defects into the metal's crystal structure. These defects prevent further slip and can reduce the grain size ...
