The first bright annealing unit of stainless steel strip in China was introduced,which integrated continuous bright an-nealing,double-stands leveling and stretch-bending straightening processes.The raw material strip gauges,production process flow,high-speed and intelligent control scheme were described as well as the technical parameters of main equipment.At the same time,the innovations of the design of the unit were introduced,which combined the double-stands leveling and tension-leveling process in the continuous annealing process of carbon steel strip to produce 200,300 and 400 series high sur-face quality 2D,2B and BA products.In addition,the inlet looper and outlet looper were designed by common rail technolo-gy,which greatly reduced the investment cost,improved the product quality and decreased the production energy consump-tion of the product.
