The development of the primary rolling mill has gone through three stages. By the early 1970s, the roll diameter of the mill has increased to 1500mm. Since 1959, China has designed and manufactured the blank opener. At present, 700mm, 750m, 850m and 1150M primary rolling mill have been made. Since 1980s, continuous casting technology has been developed greatly.

Rolling mills are becoming more and more important in modern industrial production. As producers and users, we all need to constantly learn about it. This will enable our rolling mill to play a better role. In the case of transportation and storage, we should also protect the rolling mill so as not to affect its performance. Let’s take a look at some related content.

The finishing process of the section steel mill is the important part of the production of profile steel. It will roll-form the semi-finished products for cooling, straightening, cutting, heat treatment and inspection, classification, elimination of defects, packaging, marking treatment, making it the finished steel that meets technical standards. Therefore, the level of the finishing equipment directly affects the quality of the product. One of the important signs of the modern steel rolling mill is the continuous and automated finishing equipment.

The performance application of the rolling mill constantly meets the market demand. Generally, the requirements for lubrication of the rolling mill are: solid oil is lubricated, like the conveyor roller, the tapping machine, the pusher, the vertical roller, the bearing box, base, rolling mill roller, rolling mill work roll, rolling mill press, universal joint coupling and rolling mill bracket, steel turning machine, shearing machine, disc flying shear, etc. are all lubricated with solid oil. Thin oil is generally subjected to cyclic lubrication.
