ANDRITZ receives order for second expansion stage of the Walsin Lihwa cold-rolling mill for stainless steel, Taiwan

International technology Group ANDRITZ has received an order from Walsin Lihwa to supply a stretch-bend-leveling line, a rolling mill, and a regeneration plant for the stainless steel cold-rolling mill in Taichung, Taiwan. Start-up is scheduled for the third quarter of 2016.

ANDRITZ had already received an order from Walsin in 2010 to supply the cold-rolling mill with an annual capacity of 350,000 tons.

The tension leveling line with integrated two-high skin-pass mill will process stainless steel grades AISI 200, 300, and 400. With the S6-high rolling mill, it is possible to roll hot-rolled steel with a width of 1,600 mm to a thickness of down to 0.5 mm without preliminary annealing.

In addition to optimizing its production processes, Walsin Lihwa will also be setting new standards in terms of environmental protection in stainless steel production with this order: The waste pickling liquor produced in the pickling process is treated in a Pyromars mixed acid regeneration plant, the acids of the rinse water are recovered in an additional ANDRITZ ZEMAP plant (Zero Effluent Mixed Acid Pickling), and the water loop is closed – thus the pickling line will be the first one worldwide which can be operated practically free of nitrate.

Walsin Lihwa is an established producer of stainless steel, copper, and aluminum long-products. The company has been producing hot-rolled stainless steel strip since 2003 and also started production of cold-rolled strip in 2012 with the plant in Taichung.
