摘要

介绍了最大卷重35 t、2～16 mm热轧不锈钢带退火酸洗线的工艺流程、关键设备和技术特点。该机组所生产的钢种有奥氏体、铁素体和马氏体不锈钢;退火炉使用天然气加热钢带

炉温可达1180℃

炉子总长96m;在酸洗前进行有效除鳞

酸洗的溶液为硫酸

硝酸+氢氟酸

酸洗最大速度为60 m/min

废水和废酸经回收再利用

酸雾经回收和处理。

Abstract

The process flow sheet

key equipment and technology characteristics for maximum coil weight 35 t

2 ~ 16 mm hot rolled stainless steel strip annealing and pickling line are presented. The steel grades produced in the line are austenite

ferrite and martensite stainless steel； the strip is heated in annealing furnace by natural gas

the furnace temperature is up to 1 180 °C and the total furnace length is 96 m； the effective descaling is carried out before pickling

the pickling solutions are sulphuric acid and nitric acid + hydrofluoric acid

the maximum speed of pickling is 60 m/min

the waste water and waste acid are recovered and regenerated

and the acid mist are also recovered and treated.
