热轧带钢平整机工作辊的不均匀磨损及其降低措施
Uneven wear of work roll and its reduction measurement on hot strip temper mill
摘要
Abstract
Taking 2 250 mm hot strip temper mill as a subject, uneven wear of work roll was studied. The difference between wear of hot strip mill and cold strip mill and "W" shape wear of work roll of hot strip temper mill were pointed out after measurement and analysis. Integrating its wear characteristics, the function of wear model, whose parameters were confirmed by using genetic algorithm, was constructed. The wear model which meets the requirements of project was obtained. Using the model, the wear of work roll under the condition of different shifting strategies was simulated. Simulation results show the deficiency of original shifting strategy. Based on the results, new shifting strategy is proposed and applied in industrial test, and the effects are as follows: non uniform wear of work roll is improved and service period of work roll is prolonged.关键词
