Xuanhua Iron & Steel (Group) Co., China, has contracted with Siemens VAI for the supply of a double-strand wire rod mill. Delivery is scheduled for the first quarter of 2011.
Siemens notes that this is the second project for a subsidiary company of the Hebei Iron & Steel Group in recent months.
The new rolling mills will be located in Xuanhua, Hebei Province. The new equipment will enable Xuanhua to produce rods from 5 to 25 mm in diameter, and rebar (plain and HRBF) from 6 to 16 mm. Products will include standard high carbon and alloy steel, cold heading steel, bearing steel, and spring steel.
Depending on the product mix, each strand will produce approximately 500,000 to 600,000 tonnes per year for both domestic and overseas markets. Mill output speed guarantees are 112 m/sec for 5.5- to 7.5-mm rod, 105 m/sec for 5.0-mm rod, and 85 m/sec for 6-mm HRBF rebar.
Scope of supply for each strand is for equipment from the first rolling stand through to the reform station. In the roughing, intermediate, prefinishing trains of each strand, there are 14 RedRing rolling stands, as well as two intermediate shears for cropping and emergency cutting operation.
The rod outlet equipment includes prefinishing mill #1, prefinishing mill #2, a high-speed shear arrangement, No-Twist Mill, Reducing/Sizing Mill, pinch roll, and laying head for the rod outlet. Proprietary mechatronical control systems for the shear, water boxes, reducing/sizing mill, and pinch roll include the latest Siemens S7 control system and WinCC human-machine interface. Operational change parts including 40 standby RedRing stands are also provided.
The contract covers engineering for all the equipment and site supervision for its installation and commissioning.
