不管是热扎的C型钢还是冷弯C型钢都是C型钢的一种，只不过由于对钢材的用途有所不同，所以钢的轧制就主要分为热轧和冷轧。就当前来看，热轧C型钢用途较广，二冷轧只用于生产小号型钢和薄板。除此之外还有哪些不用吗？

Whether it is hot rolled C-beam or cold-formed C-beam is a kind of C-beam, but due to the different uses of steel, the rolling of steel is mainly divided into hot rolling and cold rolling. At present, hot rolled C-beam is widely used, and the second cold rolling is only used to produce small section steel and thin plate. Is there anything else you don't need?

首先、热轧C型钢和冷轧C型钢残余应力产生的原因不同，所以截面上的分布也有很大差异。冷弯薄壁型钢截面上的残余应力分布是弯曲型的，而热扎型钢或焊接型钢截面上残余应力分布是薄膜型。

First of all, the reason of producing residual stress is different between hot-rolled C-beam and cold-rolled C-beam, so the distribution of residual stress on section is also very different. The distribution of residual stress on cold-formed thin-walled steel section is bending type, while that on hot-rolled or welded steel section is film type.

其次，热轧C型钢和冷弯C型钢的抗扭性不同。热轧型钢的自由扭转刚度比冷轧型钢高，所以热轧型钢的抗扭性能要优于冷轧型钢。

Secondly, the torsion resistance of hot-rolled C-beam is different from that of cold-formed C-beam. The free torsion stiffness of hot-rolled section steel is higher than that of cold-rolled section steel, so the torsion resistance of hot-rolled section steel is better than that of cold-rolled section steel.

然后， 热轧C型钢和冷弯C型钢的截面不同。冷轧成型钢允许截面出现局部屈曲，从而可以充分利用杆件屈曲后的承载力；而热轧型钢不允许截面发生局部屈曲。

Then, the cross section of hot-rolled C-beam is different from that of cold-formed C-beam. Local buckling is allowed in the section of cold-rolled formed steel, which can make full use of the bearing capacity after buckling; Local buckling is not allowed in hot rolled section.

以上就是关于“热扎的C型钢和冷弯C型钢的区别”的全部内容。大家也了解了那么多，找准C型钢厂家才是关键。

The above is all about the "difference between hot rolled C-beam and cold-formed C-beam". We also know so much, finding out the C-beam manufacturer is the key.
