4.50 Mt/a Wire Mill of Jiujiang Wire Company Starts up Smoothly (Engineering by CISDI)
Smooth Start-up of 4.50Mt/a Wire Rod Mill of Jiujiang Wire Company of Hebei Iron & Steel Group

The 4.50Mt/a four twin- wire rod mills designed by CISDI for Jiujiang Wire Company of Hebei Iron & Steel Group successfully passed the hot on-load test from April 15 to May 31, 2012.

The rolling mill is arranged on elevated platform. Roughing mill is of short stress design with 6 horizontal and vertical alternative stands. The intermediate rolling mill is of short stress design with 6 horizontal stands. Wires leaving the intermediate mill are rolled in Line A and B. The prefinishing mill has 2 short stress stands and 4 cantilever stands. Finishing block consists of 10 stands, all coming in V arrangement, 45° inclined to the vertical, with max. rolling speed (guaranteed) of 90m/s. With advanced production technology, high-speed rolling zone has temperature controlled water cooling device for low temperature rolling and improving structure property. Optic callipers are installed before and after the finishing block to measure the metal sizes continuously to improve product accuracy. Loose coil cooling has air regulation control technology for multiple cooling systems and uniform cooling. Advanced electrical control level and high degree of automation ensures product quality and smooth production.
