Primetals receives FAC for a modernized mill at JSW

Primetals Technologies received the Final Acceptance Certificate (FAC) for the modernized rolling mill for long products at JSW Steel Ltd. in Salem, India. The core of the modernization project was the new reversing roughing group with Red Ring stands, which enables to increase the size of the blooms to be processed to 220 mm. This consequently enables to extend the range of rolled products, both in terms of size and grade. The Red Ring stands also improve the rolling quality, with consequent reduction of defects and increase of metallic yield. 
The new reversing roughing group consists of one horizontal and one sliding vertical Red Ring stand of the fourth generation. Using blooms with 8-meter length and square size of 160 or 220 mm, a reversing sequence with up to 10 passes rolls a 104 × 112 mm intermediate product which feeds the existing finishing train. The processed grades consist of special steels for mechanical construction, tool, spring, and bearing applications.
