| 摘 要： | 针对2250热连轧机F5架(CVC)工作辊窜辊行程利用率低、窜辊分布曲线中心偏移,以及CVC工作辊磨损严重且不均匀等问题,建立CVC辊形设计数学模型,结合现场实际应用情况提出武钢2250热连轧机F5架改进的CVC辊形曲线,并给出改进CVC辊形的不同宽度带钢辊缝凸度调节能力的方法;在2250热连轧机下游F5架采用改进的CVC辊形曲线进行工业轧制实验。研究结果表明:CVC轧辊窜辊行程利用率由66%提高到80%,磨损更均匀化。

| Abstract: | Due to some problems of continuously variable crown(CVC) work roll on stand F5 of 2250 hot strip mills,for example,the shifting stroke of the CVC work rolls cannot be shifted well enough,the central position of shifting stroke is deviated and the work rolls is worn very badly and non-uniformly,and based on the developed mathematic model for CVC roll contour design method,the optimized CVC work roll contours and its performance of crown controllability were presented with the rolling operation of the production mills and were applied in downstream stand F5 of 1700 hot strip mill for test.The results show that the percentage of shifting stroke for optimized CVC work roll increases from 66% to 80%,and the wear of optimized CVC work roll is more uniform. |
