液晶显示器背光板用奥氏体不锈钢带的制作方法
摘要：
本发明公开了一种液晶显示器背光板用奥氏体不锈钢带的制作方法，通过制作精控工作辊、初轧、光亮退火、精轧、光亮退火、拉矫六个工序，制得表面光泽度GS＝280-300，±10GU、表面粗糙度Ra＝1.1-1.3，±0.05μm、不平度≤0.8mm/M液晶显示器背光板用奥氏体不锈钢带。本发明的精轧过程中的最后一道次采用精控工作辊，以及制作过程的每道工序中对不锈钢带的表面粗糙度进行管控，大幅提高产品冷轧生产效率，制得的液晶显示器背光板用奥氏体不锈钢带，提升不锈钢带表面粗糙度、光泽度、板型等指标。
摘要（英）：

The invention discloses a production method of an austenitic stainless steel band used for a liquid crystal display back light. Through six working procedures of precisely-controlled work roll production, blooming, bright annealing, finish rolling, bright annealing and withdrawal and strengthening, the austenitic stainless steel band used for the liquid crystal display back light is prepared, wherein the surface glossiness GS=280-300 +/-10 GU, the surface roughness Ra=1.1-1.3 +/-0.05 mum, and the inequality is smaller than or equal to 0.8 mm/M. According to the method, precisely-controlled work rolls are adopted by the last pass in the finish rolling process, and in each of the working procedures of the production process, the surface roughness of the stainless steel band is controlled, sothat the product cold rolling production efficiency is greatly improved; and for the prepared austenitic stainless steel band used for the liquid crystal display back light, indexes such as the surface roughness, the glossiness and the shape of the stainless steel band are improved.
