Research On Computer Control System For Prestressed Of Prestressed Rolling Mill

Prestressed Rolling Mill is a kind of rolling mill with short stress line and great rigidity. Compare with the same type of common rolling mill, it has great rigidity, simple structure and light weight, and is easily assembled and disassembled. It can improve minus deviation rolling rate greatly, assure the quality of product and increase the benefit, so it is used widely in steel rolling.With Prestressed Rolling Mill of the middle steelworks of Taiyuan Iron and Steel limited Group Company as the researched object, this article analyze the existent questions and research the initial stress of Prestressed Rolling Mill and computer control system, analyze the design thought of Prestressed Rolling Mill and clarify the relationship between the dimensional precision of rolled material and the rigidity of base of rolling mill and the main method to increase the rigidity of base of rolling mill, analyze how to confirm the rigidity , sectional area of handle and post, and pretightening force, put forward the viewpoint that the key to assure great rigidity is to assure that the remnant initial stress is always positive during rolling, and develop intelligent control system with PLC as the core on the basis of the former research to assure that the remnant initial stress is always positive during rolling. This article has some meaning in theory and practical value for improving the use of Prestressed Rolling Mill.
