涟钢CSP工作辊与支持辊辊形优化的应用研究

Optimization and Application of CVC Work Roll and Backup Roll Contour on CSP Line in Lysteel

针对涟钢CSP热连轧机上游机架CVC工作辊窜辊行程总是窜到负极限、窜辊行程利用率低,以及支持辊磨损不均匀等问题,基于大量数据统计和分析,根据CVC工作辊辊形的设计原理及引进变接触和叠加反CVC支持辊辊形技术,对上游机架工作辊及支持辊进行了优化设计。通过工业试验,取得了良好效果。

Some problems appeared in CVC（continuously variable crown） work roll and backup roll on the upstream stands of CSP hot strip mills in Lysteel,for instance,the percentage of shifting stroke of CVC work roll is very low,and the shifting position always reaches the negative capacity,and the backup rolls is worn very badly and non-uniformly.Based on a lot of statistical analysis of practical data,according to the CVC roll contour design method,and introducing backup roll technology of varying contact and anti-CVC（VCRplus）,new CVC work roll and backup contour was designed for the upstream stands.Finally,good practical results prove that it is right by industrial test.
