What is the function of the short stress rolling mill?
With the development of the steel industry and the improvement of the quality requirements of users, the requirements for rolling mills in rolling mills are getting and higher. As the main force equipment of rolling, the short stress rolling mill has the advantages of small volume, light weight, large rolling mill stiffness and long bearing life. The stress rolling mill is suitable for use as a medium rolling mill and a finishing rolling mill.
The excellent performance of the short stress rolling mill makes it the dominant model in the rolling of domestic bar and wire rod mills. The short stress line rolling mill can be roughly divided into two types: frame type and frame type. The rolling force received by the rolling mill a closed loop through the internal stress of each stressed part such as the work roll, the work roll bearing, the box, the copper nut, and the pull rod, namely the line. The base and the reducing mechanism of the rolling mill are not affected by the rolling force, and the stress line is shorter than that of the ordinary rolling mill, which improves strength of the rolling mill and reduces the elastic deformation of the rolling mill, so it is called "short stress line rolling mill".
The so-called short stress rolling mill to the rolling mill with shortened stress return line. The so-called stress return line is the closed loop line connected by the unit internal force of each stressed part of the rolling under the action of the rolling force, which is briefly called the stress line. The elastic variable of the stressed part is proportional to its length, so shortening the length of the return line can reduce the elastic deformation of the rolling mill and improve the rigidity of the frame.
