    冷弯C型钢的内应力从何而来
    发布来源:http://www.jnjgcg.com/  2016-12-28 11:42:45 发布人:济南坚固彩钢
    冷弯C型钢的内应力从何而来?跟其他冷弯型钢一样,冷弯C型钢生产过程中面临的更大问题就是内应力的问题,由于材料存在较大的内应力,一旦投入使用的话就有可能会发生变形,从而影响其使用效果。这些应力从何而来呢?
    Cold bending C steel internal stress come from? Like other cold-formed steel, the biggest problem facing the production process of cold-formed C steel is the internal stress of the problem, because the material has larger internal stress, once put into use if there may be deformed, thus affecting its use effect. Where do these stresses come from?
    冷弯C型钢的应力没有办法避免,在冷弯C型钢的开卷、滚剪、闭卷等工艺过程中,都会增加一定的内应力,更主要的就是通过机械强制变形导致冷弯C型钢具有一定的应力。除此之外,冷弯C型钢如果没有喷涂底漆,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。
    Formed C type steel stress there is no way to avoid, in the book, formed C type steel rolling shear, closed roll process, will increase the internal force, the most important is the mechanical force due to deformation of a certain stress has formed C type steel. In addition, formed C type steel without primer spraying, then rust and passivation processes will also allow it to release the internal stress caused by the bending and twist.
    在没有办法避免的情况下,就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,也要重点关注这方面的问题,确保冷弯C型钢能被广泛的运用。
    In no way to avoid the situation, only by the reasonable operation to reduce stress, as manufacturers and users, but also to focus on this aspect of the problem, to ensure that the formed C type steel can be widely used.
