当轧制其它型材时，可以用水平机架更换机架。水平机架的轧辊有很深的孔型，而机架没有。  

较大直径的水平轧辊确定型钢的的形状，而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和机架精轧轧辊时，可以获得很好的表面光洁度和尺寸公差。  

When rolling other profiles， the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass， but the universal rack does not.

Horizontal rolls with larger diameters determine the shape of the section steel， and a pair of rolls with smaller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.

（1）堆焊前需先将轧辊辊身表面的疲劳层或缺陷，尤其是裂纹必须彻底清除；  

（2）在堆焊时，为了防止裂纹的产生，必须先加工轧辊辊身预热，预热温度根据轧辊辊及堆焊材料而定。

(1) before welding， the fatigue layer or defect of the roller body surface must be first removed，crane rail， especially the crack must be thoroughly removed.

(2) in the process of surfacing， in order to prevent cracks，crane rail生产厂家， the roller body must be pre heated， and the preheating temperature should be determined according to roll rolls and surfacing materials.

线材轧机拥有粗轧机架和与小型型材轧机类似的中间机架。与两线轧制的小型型材轧机相比，crane rail价格，这些轧机一般被设计成可以进行高达4线的同时轧制的切分轧制。然而，目前的发展趋势是采用单线的高速轧制。

The wire mill has a roughing mill stand and an intermediate rack similar to a small section mill. Compared with the two section rolling mill， these mills are generally designed for rolling up to 4 lines at the same time. However， the current development trend is single line high-speed rolling.
