摘　　要：分析了涟钢CSP、2250mm生产线板形质量异议数据,通过将市场反馈数据与在线数据进行对比,找出板形质量异议存在的共性原因。根据板形质量异议的特点,通过平整工艺制度优化、辊型优化设计、板形控制模型参数调整、板形目标值修改、板形质量预判定、轧制工艺规范完善等方法,减少了板形质量异议发生的风险。通过在现场进行了一年多的质量异议分析及方案运行,热连轧机组板形质量异议半年周期内同比下降39.69%。By analyzing a large number of shape quality objection data of CSP and 2250mm rolhng lines and comparing the market feedback data with the online data, the common characteristics of shape quality objection were identified. According to the characteristics, the number of shape quality objection was reduced by means of skin pass mill process system optimization, roll contour optimization, shape control model parameter adjust- ment, shape target value modification, shape quality pre-determination system and rolling process standards optimization and so on. After more than one year of quality objection analyzing and scheme implementation, the number of shape quality objection of six months decreased 39.69%comparing with the same period of pre- vious year.
