冷连轧机组弯辊力自动设定的实现

针对大型宽带钢冷连轧机组广泛采用的液压弯辊技术，深入分析了弯辊力对于板形的调控机理．在分析轧辊辊形、带钢宽度和轧制力等因素对弯辊力设定值影响的基础上，建立弯辊力自动设定模型，并得到了现场实测结果的验证．该模型成功地投入运行，实现了冷连轧机弯辊力的计算机自动设定．

Automatic Setting of Roll-bending Force in Cold Tandem Mill

An in-depth study has been made on the hydraulic roll-bending device, which is widely used in modem cold tandem mill to regulate strip flatness. Based on analyzing the relationship of some factors associated with roll-bending force such as roll profile, strip width and rolling force etc with roll-bending force, an automatic bending-force setting model for cold tandem rolling mill was developed. The model has been successfully applied to two largest cold tandem mills in China and the experimental data proved that the model is reasonable and effective.
