What do you mean by changing rolls and grooves? Can that company change? Thank you for your questions.

Under what circumstances, each rolling line has different processes, different understandings, different habits and even different assessment mechanisms. In addition to the external dimensions, the surface roughness should also be considered in the finished groove. The change of material type is mainly considered in medium and rough rolling. Because it is not convenient to detect the rough rolling groove on line, it is generally judged by experience to replace the rolling groove. Some rolling mills often need to change rolls, because it is very troublesome to change rolls, especially when the material type changes during rough rolling. On the one hand, it causes a large number of rolls to be re-rolled, and at the same time, it causes the rolling instability of the finishing stand, and even causes accidents such as steel flying. The standard roll changing and groove changing system is beneficial to rolling stability, reducing scrap steel and improving the quality of rolled products. An effective way to solve this contradiction is to choose a rough and medium rolling roll that is wear-resistant and not easy to crack.
