Straightening process of S31254 stainless steel thin strip

The invention relates to a production method of stainless precision strip steel, in particular to a straightening process of an S31254 stainless steel thin strip. Comprising the following steps: step 1, coiling; step 2, threading; step 3, coiling; and 4, straightening. According to the method, the quarter wave problem is effectively solved by adjusting the inlet gap, the ductility, the heights of the seven sets of supporting rollers and the like, and by means of the parameters of the method, the wave height/wave length of the S31254 stainless steel precision thin strip after quarter wave straightening can be smaller than or equal to 3 IU. 本发明涉及不锈精密带钢的生产方法，一种S31254不锈钢薄带的矫直工艺。包括以下步骤：步骤一：上卷；步骤二：穿带；步骤三：卷取；步骤四：矫直。本发明通过调整入口缝隙、延伸率、7组支撑辊高度等的方式，有效解决四分之一浪的问题，使用本发明的参数，可以实现S31254不锈钢精密薄带四分之一浪矫直后的浪高/浪长≤3IU。
