C型钢不仅可以作为钢结构建筑中的檩条、墙梁；也可以自行组合成轻量型屋架、托架等建筑构件。这其中势必会涉及到C型钢的切割。下面来讲讲济南C型钢的切割工艺和应力控制如何。

C-shaped steel can not only be used as purlins and wall beams in steel structure buildings; It can also be combined into lightweight roof truss, bracket and other building components. This is bound to involve the cutting of C-shaped steel. Now let's talk about the cutting process and stress control of Jinan C beam.

C型钢的切割由于不同的切割方法具有不同的切割效果，应根据客户的要求采用。如果C型钢用于钢结构，应尽可能在切割机或锯床上切割，尤其是薄壁钢屋架。由于要求切割准确，电锯切割方法更合适，不仅效率高，而且截面光滑平整，质量好，切割偏差很小。也可以采用气割的形式，但为了保证气割的质量，尽量选择小口径喷嘴，切割后用锤子轻轻敲击，使切口平整，满足其他冷弯钢的要求，C型钢生产过程中面临的问题是内应力，因为材料内应力大，一旦投入使用，可能会变形，影响其使用效果。

Because different cutting methods have different cutting effects, the cutting of C-shaped steel should be adopted according to the requirements of customers. If C-section steel is used for steel structure, it shall be cut on cutting machine or sawing machine as far as possible, especially for thin-walled steel roof truss. Due to the requirement of accurate cutting, the electric saw cutting method is more appropriate, which not only has high efficiency, but also has smooth and flat section, good quality and small cutting deviation. Gas cutting can also be used, but in order to ensure the quality of gas cutting, small caliber nozzles should be selected as far as possible. After cutting, gently tap with a hammer to make the cut smooth and meet the requirements of other cold bending steel. The problem faced by C-shaped steel in the production process is internal stress, because the internal stress of the material is large, once put into use, it may be deformed, affecting its use effect.

C型钢没有办法防止型钢的应力，主要是由于机械强制变形造成的C型钢加工有一定的应力。C型钢不喷涂底漆，那么除锈和铺装工艺也会使其内应力释放，导致弯曲和扭转。在无法预防的情况下，我们只能依靠合理的操作来减少应力的产生。作为制造商和用户，我们也应该关注这个问题，以确保C型钢的应用。

There is no way to prevent the stress of the C section steel, mainly because the processing of the C section steel caused by mechanical forced deformation has a certain stress. If C-shaped steel is not sprayed with primer, the rust removal and pavement process will also release its internal stress, resulting in bending and torsion. In case of no prevention, we can only rely on reasonable operation to reduce the stress. As manufacturers and users, we should also pay attention to this problem to ensure the application of C-beam.

此外在实际应用中对于C型钢壁的厚度要求不同，如果要同时满足这些要求的话，所以选用的C型钢生产工艺和设备非常关键。一般了冷轧方式是难以生产出的C型钢，因此得用C型钢机来完成。

In addition, the thickness requirements for C-shaped steel wall are different in practical application. If these requirements are to be met at the same time, the selected C-shaped steel production process and equipment are very critical. Generally, the cold rolling method is difficult to produce the C-beam, so the C-beam mill must be used to complete it.

为了达到准确的壁厚，在压制C型钢的时候，使用的模具是由一个上模和一些大小规格尺寸相同的下模构成的。在加工之前将它们安装到位，不仅要上模与下模能够顺利的，还得四周边间隙均匀，这样压制的C型钢才能壁厚均匀。

In order to achieve accurate wall thickness, when pressing C-shaped steel, the mold used is composed of an upper mold and some lower molds with the same size and specification. Before processing, if they are installed in place, not only the upper mold and lower mold can be smooth, but also the four peripheral clearance is uniform, so that the pressed C-shaped steel can have uniform wall thickness.

总之，由于不同的切割方法有着不同的切割效果，因此需要按照客户的要求进行适当的选用。对于该材料，您有什么问题或者需求，可以随时来我们网站http://www.jnhscg.com进行咨询了解！
