The revamp entailed installation of a new roughing mill with heavy edger, two new descalers, a new coilbox and an upgrade of its finishing mill. Motors and drives on coilbox and the finishing mill’s pinch roll descaler were replaced and new level 1 and level 2 automation systems for the roughing and finishing mill were installed. 

Primetals Technologies said the revamp further increases the facility’s competitiveness through the extension of product mix, improved quality, increased productivity and reduced production costs.
 
The project will grow capacity from 1.36 to 2.5 million metric tons per year. A state-of-the-art automation system makes the plant ready for Industry 4.0, Primetals Technologies said.
