High-capacity wire rod mill with FRS® technique

The wire rod outlet comprises a cooling and equalising section in a loop arrangement, a six-stand wire rod block and a four-stand FRS® (Flexible Reduction and Sizing) block – both in UHD (Ultra-Heavy Duty) arrangement. The wire-rod block and the FRS® block are each followed by a water-cooling line. The core component of the mill is the FRS® block together with the cooling and equalising section. The supply scope therefore also includes the 104m long LCC® (Loop Cooling Conveyor) for forced and retarded cooling, a total of three water cooling lines and the CCT® (Controlled Cooling Technology) system developed by SMS Meer. These facilities allow wire rod to be produced over the entire dimensional range of 5.5mm to 25mm by means of temperature-controlled rolling. Ultra- fine microstructures can be achieved especially for cold-heading grades by thermomechanical rolling. The maximum rolling speed for 5.5mm wire rod will be 120m/sec.

The SMS Meer contract includes a walking-beam furnace, the mechanical and electrical equipment of the mill train, all of the supply systems, the finishing facilities for the wire-rod coils, the entire rolling and cooling equipment, and the erection and installation. The walking-beam furnace for billets up to 155mm square will reach an output of 120t/hour.

ArcelorMittal Hochfeld GmbH has placed an order with SMS Meer for the supply of a complete high-capacity wire rod mill with FRS® technique for high-grade steels. The mill’s annual capacity will be 690,000t. Of this, the major portion of the products is expected to be cold heading steel grades. The mill will be designed for producing wire rod in high-grade steels and will be in production in August 2010.
