Method for controlling dirty marks on surface of 301-series stainless steel wide panel

The invention relates to reversible cold rolling of a 301-series stainless steel wide panel, in particular to rolling of the 301-series stainless steel panel with the thickness smaller than or equal to 2.0 mm and the width larger than or equal to 1500 mm. A method for controlling dirty marks on the surface of the 301-series stainless steel wide panel comprises the following steps that firstly, the rolling technology is standardized; secondly, the rolling plate shape technology is standard; and step 3, carrying out rolling oil flow process specification. After the method is adopted, the problem of oblique wave-shaped white stripe-shaped dirty mark defects of the 301 series stainless steel wide panel is successfully solved, and the percent of pass reaches 100%. 本发明涉及301系不锈钢宽幅面板的可逆冷轧，主要是厚度≤2.0，宽度≥1500mm规格的301系不锈钢面板轧制，一种301系不锈钢宽幅面板表面脏印控制方法，包括以下步骤：步骤一：轧制工艺规范；步骤二：轧制板形工艺规范；步骤三：轧制油流量工艺规范。采用本发明方法后，成功解决了301系不锈钢宽幅面板斜向浪形白色条纹状脏印缺陷问题，合格率达到100%。
