用电流加热且在一个轧机机架中实现塑性变形的称电塑性轧制。此时 ,采用电接触 (直接 )加热 ,加热的数学模型在大多数情况下可以忽略料坯的导热性。然而在料坯运动速度较小的电塑性轧制中 ,料坯的导热性会对电加热有显著的影响。因此 ,该轧制过程中加热数学模型应该估计到料坯 Electrically plastic rolling with current heating and plastic deformation in a roll stand. At this point, the use of electrical contact (direct) heating, heating the mathematical model in most cases can ignore the thermal conductivity of the blank. However, in the electro-platen rolling with low material moving speed, the thermal conductivity of the preform will have a significant effect on the electric heating. Therefore, the mathematic model of heating during the rolling should be estimated to blanks
