一、概况为使冷轧钢板表面状态最佳化,钢板表面应按严格的技术规范进行相应的表面处理,以保证钢板具有良好的使用效果。对于钢板四大质量指标中的理化性能、尺寸精度、板形状况早已进行了深入的研究。近期,对钢板表面状态质量提出日趋严 I. Overview In order to optimize the surface condition of the cold-rolled steel, the surface of the steel should be treated according to strict technical specifications to ensure that the steel plate has a good effect. For the four quality indicators of steel physical and chemical properties, dimensional accuracy, shape shape has long been an in-depth study. Recently, the state of the surface of the steel quality is increasingly stringent
