冷弯C型钢是用热卷板进过冷弯加工而成的，相比传统的C型钢而言，这种产品具有壁薄自重轻、截面性能优良、强度高等优势，因此在同等强度要求下可以起到节约材料的目的。说到它的应用，自然受到了广泛的关注。下面济南C型钢厂来讲讲冷弯C型钢表面发黑的处理流程。

Cold formed C-shaped steel is processed by hot coil and cold bending. Compared with traditional C-shaped steel, this product has the advantages of thin wall, light weight, excellent section performance and high strength. Therefore, it can save materials under the same strength requirements. When it comes to its application, it has naturally received extensive attention. Next, Jinan C-beam Steel Plant will talk about the treatment process of surface blackening of cold-formed C-beam steel.

由于材质和使用环境等因素的影响，冷弯C型钢表面会有发黑的现象，要是不及时予以处理的话，冷弯C型钢的品质后进一步恶化。针对不同的情况，采用的清洗流程也是不同的。

Due to the influence of materials, service environment and other factors, the surface of cold-formed C-shaped steel will be blackened. If it is not treated in time, the quality of cold-formed C-shaped steel will further deteriorate. The cleaning process is different for different situations.

如果冷弯C型钢表面的油污不是很多，也没有厚的氧化皮的话，可以采用中温除油、水洗、常温除锈活化、水冲洗、水漂洗等工序。只要各道工序都处理到位的话，冷弯C型钢能恢复原有良好的状态。但如果冷弯C型钢避免有厚氧化皮、厚油污的话，好要用喷砂处理，实现清洁生产。

If there is not much oil stain or thick oxide skin on the surface of cold-formed C-section steel, such processes as medium temperature oil removal, water washing, normal temperature rust removal and activation, water washing and water bleaching can be used. As long as all processes are properly handled, the cold formed C-beam can be restored to its original good condition. However, if the cold-formed C-section steel is free of thick oxide skin and oil stain, it is better to use sand blasting to achieve clean production.

有的冷弯C型钢上还有深孔、盲孔等，对于这类材料要采用超声波除油、水洗、除锈活化、水洗等才能有效的去除其表面发黑现象，整个过程又快又好。

Some cold-formed C-section steels also have deep holes, blind holes, etc. For such materials, ultrasonic oil removal, water washing, rust removal activation, water washing, etc. are required to effectively remove the surface blackening phenomenon. The whole process is fast and good.

冷弯C型钢可以用于钢结构建筑的檩条、墙梁，也可自行组合成轻量型屋架、托架等建筑构件。此外，冷弯C型钢在制作机械轻工制造中的柱、梁和臂等部件也有很好的效果。而且材料的规格、长度等都是可以根据要求设计确定的，非常灵活。您有什么需求可以随时来我们网站http://sxhtyz.com进行咨询！

Cold formed C-shaped steel can be used for purlins and wall beams of steel structure buildings, and can also be combined into lightweight roof trusses, brackets and other building components. In addition, the cold-formed C-shaped steel also has a good effect in the manufacture of columns, beams, arms and other components in mechanical light industry. Moreover, the specification and length of materials can be determined according to the design requirements, which is very flexible.
