With two main function sections, annealing and pickling, the line design production capacity is 100, 000-200, 000 tpy; The raw material will be cold rolled CR AISI300/400 series stainless iron with specifications of 0.2-1.5 X 1000-1270 mm; The process section speed is Max. 80m/min, and mainly accomplishes the annealing and pickling, also can realize the middle annealing and product annealing of cold rolled strip. The product quality accords with the JIS G4304 and GB4237-92standard.

Line main feature:
Combines advanced annealing and pickling process technology, which ensures the product quality.
Sets pre-process section to get rid off the rolling oil on the strip surface, which ensures the quality of the final product.
In the annealing section, combines the pre-heating section and fuel gas direct heating section, and sets air heat exchanger to assist the combustion, which efficiently improves the heating efficiency and heat utilization rate. The air after pre-heating can be used for drying, which improves the heat recovery rate and decrease the running cost.

In the pickling section, uses multilevel mixed acid pickling and cascading rinsing technology to ensure the pickling result.
Adopts AC frequency driving control system, which has good human-machine interface and the maintenance of the equipment is easy.
