所谓低温热轧是指稍高于再结晶温度下的轧制。提高轧制温度可以降低轧件温度的屈服应力，使变形功降低。但是由于变形功可以转化为热量，因此，当轧件温度的热损失主要是热辐射时，热损失量与轧件温度的4 次方成正比。
The so-called low temperature hot rolling is a rolling that is slightly higher than the recrystallization temperature. Increasing rolling temperature can reduce yield stress of workpiece and reduce deformation work. However, the deformation work can be converted into heat, so when the heat loss of the rolling temperature is mainly heat radiation, the amount of heat loss is proportional to the 4 time of the rolling temperature.
横轧有两种类型：一类是轧辊孔型沿轴向是不变的，沿径向呈周期变化。轧件主要靠径向变形实现成型。另一类是锲横轧工艺，即在两个或者三个互相平行布置的轧辊或两个平板的表面上.
There are two types of cross rolling: one is the roll pass is unchanged along the axis, and the other is radial variation. The workpiece is mainly formed by radial deformation. The other is the cross rolling process, that is, on the surface of two or three parallel rolls or two plates.
