Principle of steel rolling heating furnace

The principle of heating furnace 1. Purpose The purpose of heating is to heat the billet to a uniform temperature suitable for rolling (austenite structure). After the temperature is increased, the plasticity of the steel is first increased, the deformation resistance is reduced, and the steel is easily deformed. For example, the deformation resistance of […]
