轧制速度控制：即轧制时对各道次轧辊的线速度以及每道中不同阶段的轧辊的速 度的具体规定，也叫速度规程。

Rolling speed : that is to say， the speed regulation is also specified for the speed of each roller and the speed of each roller different stages in rolling.

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，轧钢设备型号，轧件在孔型中轧制，并且在每个孔型中轧制一道，因此，轧钢设备报价，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， deformation of the total deformation of each unit of each pass，轧钢设备生产， rolling etc.. For the secti*teel， the rolled piece is rolled in the pass and rolled in one pass. Therefore， the deformati*ystem of the secti*teel is expressed in the form of pass， and the deformati*ystem is determined after the pass design is determined.

轧钢原料：

目前主要为连铸坯，另外还有钢锭，段轧钢等，正确的选择坯料的种类，断面形状和尺寸大小以及重量对轧钢生产具有重要意义。

Rolling material:

At present， mainly for continuous casting billets， as well as steel ingots， section rolling，轧钢设备， etc.， correctly choose the type of billet， secti*hape and size and weight are important for steel rolling production.
