650kW Green 8mm Low - Oxygen Copper Continuous Casting Machine 15 tons/hr





1. Application and Composition

This plant works to produce low-oxygen copper rod in 8mm diameter by means of

continuous casting and rolling process, with cathode and copper scrap as the raw material.

The plant is composed of one set of tilting&refining furnace with 30 tons capacity,

five-wheel casting machine, drive unit, roller shears, straightener and burring unit, shaver,

rolling mill, coiler, and electrical control system. If cathode is used, a melting furnace(shaft

furnace) with 16-ton/hour capacity and 12-ton holding furnace are required.


2. Brief Process Flow

Charging copper scrap (grade 1 or grade 2) → melting and refining in tilting&refining

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 → winding unit to pre-shape rod →

star coiler to lay rod into coil.


3. Copper Scrap as raw material

Red copper scrap as the raw material must be Grade 1 or Grade 2.

3.1. Copper scrap on excellent grade (Pb<100, Sn<300, Ni<50, Zn<50, Fe<50 and Sb<20)

should be clean and non-alloy copper wires free from tin, containing no fragile burned

wires.copper contentno less than 98%

3.2. Copper scrap on grade 2 (Pb<1000, Sn<800, Ni<150, Zn<300, Fe< 500, Sb<100, S<200)

should be small director copper wires without insulation, usually containing telephone

wires, copper bus bar with varnish coating or paper insulation, and thick or thin, clean

copper bar.copper contentno less than 94%

Charging raw material requirement:grade1(copper contentno less than 98%) must be more than 50%,

grade 2(no less than 94%) no less than 30%,motor’s enamelled wire <20%(copper contentno less than 92%).
