摘　　要：通过开发超薄规格花纹板专用MSU压下模型、层冷CTC模型,结合芯轴张力参数优化,解决了超薄规格花纹板平直度、卷形不良问题,平整≤2.0 mm规格切损率降低3.08%,质量废次降率降低3.79%。通过优化辊型配比、花纹辊上下辊压差等措施,解决了超薄规格花纹板脱槽困难及花纹高度不足问题,配合专用层冷CTC模型及层冷辊道超前率优化,解决了头部上飘问题,降低事故风险,提高轧制稳定性。通过平整工艺生产流程的成功开发与贯通,薄规格花纹板平整前板形正常的比例由49%提高至73%,平整后板形正常的比例在94%以上。By developing a special MSU compression model and a layer cooling CTC model for ultra-thin specification patterned plates,combined with optimization of core tension parameters,the problems of flatness and poor roll shape of ultra-thin specification patterned plates have been solved.The cutting rate of flat≤2.0 mm specifications has been reduced by 3.08%,and the quality waste rate has been reduced by 3.79%.By optimizing the roller ratio and the pressure difference between the upper and lower rollers of the patterned roller,the problems of difficulty in groove removal and insufficient pattern height in ultra-thin patterned plates have been solved.Combined with a dedicated layer cooling CTC model and optimization of the layer cooling roller advance rate,the problem of head floating has been solved,reducing the risk of accidents and improving rolling stability.Through the successful development and integration of the leveling process,the proportion of thin specification patterned boards with normal shape before leveling has increased from 49%to 73%,and the proportion of boards with normal shape after leveling is over 94%.
