Induction heating in forging production
An important feature of mankind is the ability to use nature and transform nature. Since the late Stone Age, humans have invented smelting techniques and learned the ability to make tools, weapons, and even decorations from metal. The casting and forging techniques have also begun a long process of development, with a history of more than two thousand years. So far, the technology has penetrated into various fields of human survival.
Today's forging concept includes free forging, die forging, extrusion, rolling, cold heading, cold punching and ramming, and many other methods, except for cold heading and cold punching at room temperature, no matter what kind of forging is used. In the method, the metal blank to be forged is preheated to make the metal have good plasticity and low deformation resistance. The forged metal has a denser structure and higher mechanical properties.
