1. Application and Composition

This plant works to produce low-oxygen glossy copper rod inφ8mm diameter by means of continuous casting and rolling process, with cathode as the feedstock.

The plant is composed of 1 set of vertical furnace with 18t/h capacity, 1 set of rotary holding furnace with 12t capacity, five-wheel casting machine, drive unit, roller shears, pieces spindling machine, straightener and burring unit, shaver, high-pressure phosphorus removal system, feeding device, rolling mill, rewinding device, waxing device, coiler, lifting platform and take-up roller way, packing machine and packing way, and electrical control system, etc.

1. Brief Process Flow

Copper cathode → melting and refining in reverberatory furnace → rotary holding furnace → launder to protect molten copper → ladle → casting machine to get cast bar → roller shears → straightener → burring unit → shaver to treat cast bar → feed-in unit → rolling mill → cooling unit to quench rod → waxing device→winding unit to pre-shape rod → star coiler to lay rod into coil→packing device.
