The steel bars used in the rod mill will have problems due to material selection, quality problems or improper operation of the rod mill, which will seriously affect the working efficiency of the rod mill. Therefore, we must pay attention to these problems when using them. The following is a summary of some of the most common problems of steel bars in rod mills for your reference.

1. Broken bar. The reason is that the interior of the material is loose. Steel billet problem, only super-large steel mills can meet the technical requirements of internal compactness, especially the diameter of more than 70 mm. Although most steel mills can finish molding, the compression ratio and hardenability are very low, that is, the organization is not tight. In addition, the internal stress of round steel has not been relieved before leaving the factory, and the broken bar is like an explosion, which started from the inside. The principle of steel bar production in steel mills is like blowing a balloon, and the internal stress must be relieved to prevent the broken bar.
