With this investment in a Kocks Reducing+Sizing Block, Baosteel can meet its customer's requirements for specialty steel in different dimensions, thus further expanding its business activities.

Baosteel Group is a state-owned enterprise of the People’s Republic of China. With a cumulated production of 120 million tons per year, it is the world's leading steel producer. Its subsidiary Baoshan Iron+Steel Co., Ltd. produces 34.9 million tons of iron and steel each year, which places it second in terms of production among Chinese iron and steel companies and fifth in the world.

With the decision to equip the new rolling mill with a Kocks Reducing+Sizing Block of the latest generation, Baoshan is continuing the successful cooperation between the two companies, which began in 2003 with the key investment into a “RSB 370/4” for the combined high-capacity SBQ rolling mill “Shanghai No. 5”.

The new “RSB 300++/4” will be located as finishing unit after 14 stands in H/V arrangement in a 600,000t/a combined SBQ bar in coil and wire rod mill. It will produce bars in coil within a dimension of Ø 18.00mm to 50.00mm and feeders for the wire rod line to finish dimensions of Ø 7.5mm to 28.0mm. The “RSB” comes with a remote control for stand and guide adjustments, equipment for the roll-shop and Kocks proprietary software solutions. Commissioning is scheduled for the end of this year.
