摘要
动态轻压下控制模型的开发与应用是实现轻压下参数有效、稳定实施的关键环节。结合攀钢2号大方坯连铸机设备特点,研究开发了大方坯动态轻压下控制模型,阐述了轻压下实施过程中各拉矫机压下辊设定值的计算方法。模型投用后铸坯内部质量得到显著改善,铸坯中心疏松≤0.5级综合比例和中心偏析≤0.5级综合比例分别提高35.46%和9.81%。
The development and application of dynamic soft reduction model is the key link which realized the stable and effective application of soft reduction parameters. A bloom dynamic soft reduction control model was studied which combined with Panzhihua steel No. 2 bloom continuous casting machine equipment characteristics, and the gap values calculation method for the press rolls of withdrawal and straightening machines during the process of soft reduction were described. The model application results showed that the blooms inner quality had been improved obviously, and the comprehensive percentages of blooms central segregation defects class 40.5 and central looseness defects class 40.5 respectively increased by 35.46% and 9.81%.
