The Optimization Study Finish Work Roll Changing System Of 1780mm Hot Strip Rolling Plant In Baosteel

With the development of the steel industry and market competition,Chinese steel industry has stepped into more intense competitive environment.In order to enhance the capacity of 1780mm hot rolling production line in Baosteel Stainless Steel Co.,Ltd and increase the operation time,this topic idea mainly optimizes the roll process to reduce the time and improve hot strip rolling line of annual production through the study of work rolls in finishing mill roll.It has an extensive application value to promote the major iron and steel enterprises of hot rolling production.Based on the actual situation of Baosteel 1780 stainless steel finishing mill work roll system,through investigation and study,the roll changing system with changing equipment and the process are analyzed in details.Baosteel 1780mm hot rolling finishing mill work roll changing equipment,process,automatic control system and related models are researched.Optimization of work rolls in finishing mill for roll system of some common control methods are analyzed and some methods of improvement are put forward.Mainly focusing on function of the relevant optimization of changing work rolls in finishing mill roll system,cart position and proximity switch management are focused on,a key stop function module development,automatic control are designed for optimization.This thesis introduces 1780 precision roll replacement process which was studied.It uses statistical tools to analyze process stability and control measures.The efficiency of the work roll change is improved and the waste of work and determination of the single minute exchange is eliminated.The optimization of method for the whole process shorten the work roll change time and eliminaten unnecessary waste.The research includes 4 aspects:the establishment of data tracking system;action research work roll change device;the part of the equipment movement order and speed which shorten the time of the whole equipment movement;work roll change in the process of data to find out the reasons affecting flow fluctuation and to resolve and control roll change control process;work roll for optimizing work procedures.
