智能化高速双平整、拉矫不锈钢光亮退火机组介绍

Introduction of intelligent high-speed double-leveling and straightening stainless steel bright annealing unit

介绍了国内首条集连续光亮退火、双机架平整、拉弯矫直工艺为一体的不锈钢带钢光亮退火机组情况,包括原料带钢规格、工艺流程、高速智能化控制方案,以及主要设备的技术参数;同时,介绍了该机组设计的创新点,其结合了碳钢板带连续退火过程中双平整+拉矫工艺,用以生产200、300、400系高表面质量2D、2B及BA产品。此外,入口活套、出口活套采用共轨道工艺设计,大大降低了投资成本,在提高产品品质的同时降低了产品的生产能耗。

The first bright annealing unit of stainless steel strip in China was introduced,which integrated continuous bright annealing,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 surface quality 2D,2B and BA products.In addition,the inlet looper and outlet looper were designed by common rail technology,which greatly reduced the investment cost,improved the product quality and decreased the production energy consumption of the product.
