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.
合格的单根坯料经提升装臵将其提升到 5.0m平台辊道上，通过运送辊道进入入炉辊道，由推钢机推入加热炉，蓄热推钢式加热炉按不同钢种的加热制度，将坯料加热到980-1150℃，加热炉的设计能力为:冷坯160t/h，热坯180t/h。
Qualified single blank by lifting device to the 5.0m platform on the rollers， by transporting roller into the furnace roller，圣霖轧钢设备生产厂， the pusher is pushed into the heating furnace， regenerative pusher type reheating furnace in heating system of different steel grades，圣霖轧钢设备， the blank is heated to 980-1150 DEG C， the design of heating furnace capacity: cold billet 160t/h 180t/h，圣霖轧钢设备采购， hot slab.
轧钢机在辊系的装配上，***主要的应该是轴承的使用，圣霖轧钢设备厂家，虽然短圆柱的轴承在寿命上都比较长，而且承载的能力也比较大，但是，其不可以承受轴向力，因为使用的是双列较的接触轴承.
The main part of the rolling mill assembly of the roll system should be the use of the bearing. Although the bearing of the short cylinder is long in life， and the capacity of the bearing is relatively large， it can not bear the axial force， because the use is a double row of contact bearing.
