轧制H型钢时，***轧机作为***机架使用，带有两个水平辊和两个立辊，对轧件的腹板和翼缘四面碾压。轧制普通型钢时，***轧机转换成两辊机架，即不带立辊，只带有两个水平辊，对轧件进行轧制.
When rolling H steel, the universal mill is used as a universal frame, with two horizontal rolls and two vertical rolls, which are rolled over the web and flange of the rolled piece. When rolling ordinary steel, the universal rolling mill is converted into a two roll frame, that is, without a vertical roll, with only two horizontal rolls, rolling the rolled piece.
楔横轧机类型有辊式、板式和单辊弧式楔横轧机。三种类型的楔横轧机相比，板式楔横轧机模具制造较为简单，模具的调整比较容易，因而轧件的精度较高，并且工艺可靠.
The cross wedge rolling mill has roller type, plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill, the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy, so the precision of the workpiece is high and the process is reliable.
轧机***厂家说，热轧机的优点主要可以归纳为三个方面。一点，采用热轧可以明显的减少能耗，降低成本。此外，热轧时可以发挥出较高的金属塑性，而且所产生的变形抗力较小，能够有效的防止金属出现严重的变形问题。
The mill manufacturer explains that the advantages of the hot rolling mill can be summed up in three aspects. First, the use of hot rolling can significantly reduce energy c***umption and reduce costs. In addition, hot rolling can give full play to the high metal plasticity, and the deformation resistance is ***all, which can effectively prevent the serious deformation of the metal.
