UL-255/12 Copper Rod Continuous Casting & Rolling Line

The continuous casting & rolling line for copper is used for making the copper rod in 8mm

It consists of melting furnace (shaft or radiant furances upon user’s option), holding furnace, casting machine, pinch rollers, hydraulic shearer, straightening & burring machine, stripper, rolling mill and coiler.
