The application of C-section steel processing can be said to be quite extensive, which can not only be used as purlin and wall beam in steel structure buildings; It can also be combined into lightweight roof truss, bracket and other building components. No matter what kind of use, it will involve the cutting of C-section steel processing. Because different cutting methods have different cutting effects, they need to be selected appropriately according to the requirements of customers.

一般情况下，c型钢加工在钢结构中应用的话，它的切割尽可能选择在剪切机上或锯床上进行，尤其是对于薄壁型钢屋架。之所以小编这样建议，是因为这里要去下料要准确，易电动锯割法做为适合，不仅工效高，而且断面光滑平整、质量好，切割误差非常的小。

Generally, if C-section steel processing is applied in steel structure, its cutting shall be carried out on shear machine or sawing machine as far as possible, especially for thin-wall section steel roof truss. The reason why Xiaobian suggests this is that the blanking here should be accurate, and the easy electric sawing method is suitable. It not only has high work efficiency, but also has smooth and flat section, good quality and very small cutting error.

c型钢加工切割的效果怎么样

What is the effect of C-section steel processing and cutting

c型钢加工也可以采用气割的方式，但为了提高气割质量，尽量采用小口径喷嘴，并在切割后用锤子轻轻敲打，使切口平整，满足各种用途的要求。

C-section steel can also be processed by gas cutting, but in order to improve the quality of gas cutting, try to use small-diameter nozzle, and gently tap with a hammer after cutting to make the incision flat and meet the requirements of various uses.

跟其他冷弯型钢一样，c型钢加工生产过程中面临的问题是内应力的问题，由于材料存在较大的内应力，一旦投入使用的话有可能会发生变形，从而影响其使用效果。

Like other cold-formed sections, the problem faced in the processing and production of C-section steel is the problem of internal stress. Due to the large internal stress of the material, once it is put into use, it may deform, which will affect its use effect.

c型钢加工的应力没有办法避免，在冷弯c型钢加工的开卷、滚剪、闭卷等工艺过程中，都会增加一定的内应力，主要的是通过机械强制变形导致冷弯c型钢加工具有一定的应力。除此之外，冷弯c型钢加工如果没有喷涂底漆，那么除锈和钝化工艺也将会使得它的内应力释放出来，造成弯曲和扭变。

There is no way to avoid the stress of C-section steel processing. A certain internal stress will be increased in the process of uncoiling, rolling shear and closing of cold-formed C-section steel processing. The main reason is that the cold-formed C-section steel processing has a certain stress through mechanical forced deformation. In addition, if the cold-formed C-section steel is not sprayed with primer, the rust removal and passivation process will also release its internal stress, resulting in bending and torsion.

在没有办法避免的情况下，只能通过合理的操作来减少应力的产生，作为生产厂家和用户而言，也要关注这方面的问题，确保冷弯c型钢加工能被广泛的运用。

When there is no way to avoid it, we can only reduce the stress through reasonable operation. As manufacturers and users, we should also focus on this problem to ensure that the processing of cold-formed C-section steel can be widely used.
