Stability Research and Optimization Improvement of Balance System for Working Rolls of Wide and Thick Plates
The production capacity of Laigang's 4 300 mm wide and thick plate production line has been continuously increasing,from 1.16 million tons in 2016 to 1.71 million tons in 2022.However,the failure of the work roll balance system remains high.In response to this issue,the reasons for the malfunction of the work roll balance system of the rolling mill were analyzed,and based on the analysis results,corresponding optimization plans were formulated one by one from the external environment,internal structure,spare parts quality,and assembly accuracy improvement of the work roll balance system operation.After completing the relevant improvements,the failure rate and maintenance costs of the work roll balance system of the rolling mill have been significantly reduced,reducing maintenance costs and providing huge support for stable production and increased production capacity of the production line.
