New SCR copper rod mill for Jinchuan Group

Primetals has been awarded a contract from Southwire to supply rolling mill equipment for a new Southwire Continuous Rod (SCR) copper rod system for the Jinchuan Group Company in Gansu Province, China. Jinchuan Group will begin producing electrolytic tough pitch (ETP) copper from the new SCR copper rodmill in mid-2024.

The company will use the new system to manufacture wire and cable for the construction industry. This is the third SCR copper rod system that Jinchuan has ordered, further strengthening the well established long-term business relationship, and providing additional evidence of the value of the solutions offered by Primetals Technologies and Southwire. Primetals Technologies will engineer, supply, and implement the rolling mill, coiler, and a large portion of the coil handling equipment. The Southwire “SCR 7000” rolling mill includes a Morgan No-Twist mill with 13 independently driven roll stands.

The contract also includes a 610mm entry shear and table, one 457mm roughing mill stand, four 305mm roughing mill stands, one 320mm rotary shear and downloop table, and eight 203mm finishing mill stands, all with hydraulic roll mounting, a rod cooling and cleaning system with injectors and air wipes, rollerized turndown, two pinch rolls, coiler, designs for an inline conveyor system, and two oil lubrication systems.

Based in Carrollton, Georgia, Southwire Company developed the SCR process in 1963. It has partnered with Primetals Technologies to implement new and updated systems for decades. Globally, more than 50 percent of all copper rod is currently produced using the SCR process.
