Technical Research of Alloy Bar’s Rolling with Cooling

Abstract

The rolling force model and energy calculation equation for 20CrMnTi steel are constructed based on practically measured data and theoretical math model. In the practical production, the heating temperature of 20CrMnTi steel is lowered from 1150°C to 1050°C, and in consequence, the total energy consumption is reduced by 5.81%. Moreover, the mill and motor abilities are still met and the rolled goods’ properties and surface quality are still guaranteed. Thus, energy saving is successfully realized.
