摘　　要：针对传统冷轧不锈钢生产大多由相对独立的生产单元组成、生产成本较高的问题,介绍了某年产70万t联合式冷轧不锈钢轧制退火酸洗机组。主要介绍了该机组工艺流程、主要工艺技术参数,活套主要参数,以及轧机、退火和酸洗机组、平整机、拉矫机的技术特点。同时,还介绍了机组采用的先进酸雾净化技术、中性盐电解液回收技术和余热利用技术等节能减排措施。该机组所有机械设备均为国内自主设计、供货,为提升我国不锈钢冷轧核心竞争力将起到至关重要的作用。In view of the problem that the traditional cold-rolled stainless steel production is mostly composed of relatively inde pendent production units and high production cost,a combined rolling,annealing and pickling line with an annual output of 700000 tons was introduced.The technological process,main technical parameters and looper parameters of the mill,annealing and pickling unit,temper mill and tension leveller were introduced.At the same time,the advanced acid mist purification technology,neutral salt electrolyte recovery technology and waste heat utilization technology adopted by the unit were also introduced.All the mechanical equipment of the unit were designed and supplied independently in China,which will play an important role in im proving the core competitiveness of stainless steel cold rolling in China.
