A new combination bar, bar in coil and wire rod mill has recently been commissioned at YongXing Special Stainless Steel Co. Ltd. in Huzhou City, China. The mill is designed to produce 250,000 tons per year of stainless valve steels, nickel-based alloy steel and numerous stainless grades, including austenitic, ferritic, dual phase and hardening steels. The new rolling mill, supplied by Primetals Technologies, has capabilities for rolling wire rod in sizes 4.5 – 16.0 mm, bar in coil from 16 – 40 mm and straight bar from 30 – 130 mm. The equipment includes quenching and heat treatment facilities to maximize in-line processing, plus new innovations such as stepless coil reforming for wire rod and optical bar counting for straight bar products, all selected to deliver higher grade stainless products. As production in the new mill continues to increase, YongXing is able to meet demands of customers seeking special grades for applications in the nuclear, automotive and petrochemical industries, among others, affirming their position as a top stainless steel supplier in China. This paper presents several modernization solutions that take advantage of equipment and process innovations and examines the resulting improvements.
