钢锭或钢坯在常温下很难变形，不易加工，需要进行加热到1100℃到1250℃进行轧制，这种轧制工艺叫做热轧。在常温下的轧制一般理解为冷轧.

Ingot or billet are difficult to be deformed at normal temperature and are not easy to be processed. They need to be heated to 1100 and 1250 C for rolling. This rolling process is called hot rolling. Rolling at normal temperature is generally understood as cold rolling.

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℃，圣霖轧钢设备生产，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， the pusher is pushed into the heating furnace， regenerative pusher type reheating furnace in heating system of different steel grades， the blank is heated to 980-1150 DEG C， the design of heating furnace capacity: cold billet 160t/h 180t/h， hot slab.

轧制变形制度：即一定轧制条件下从坯料到成品的总变形量和轧制的总道次，各机组的总变形量各道次的变形量，轧制方式等。对于型钢，轧件在孔型中轧制，并且在每个孔型中轧制一道，因此，型钢的变形制度是以孔型的形式表示的，孔型的设计确定后变形制度就确定了。

Rolling system: that under certain rolling condition the total deformation from the blank to the finished product and the total rolling pass，圣霖轧钢设备厂家， deformation of the total deformation of each unit of each pass， rolling etc.. For the section steel， the rolled piece is rolled in the pass and rolled in one pass. Therefore， the deformation system of the section steel is expressed in the form of pass， and the deformation system is determined after the pass design is determined.
