1This plant works to produce low-oxygen glossy copper rod in 8 mm diameter by means of continuous casting and rolling process, with cathode or red copper scrap as the feed stock.
The plant is composed of 1 set or 2 sets of reverberatory with 60-ton capacity, five-wheel casting machine, drive unit, roller shears, straightener and burring unit, shaver, rolling mill, coiler, and electrical control system.
2. Red Copper Scrap as Feedstock
Red copper scrap as the feedstock must be Grade 1 or above Grade 2.
Copper scrap on excellent grade (Pb
This machine works to draw î¦8mm copper rod into copper wire ranging from î¦1.2-4.0mm and further softens the wire by direct annealing, and then the wire is taken up into î¦630 or î¦500 bobbin by dual spooler or coiler by î¦800 coiler. The product conforms to the the requirements of the chinese national standard gb3953.

Application
By means of continuous casting & rolling, this line works to produce oil-free conductive aluminum rod in a diameter 9.5mm or 2mm. or 5mm.
2. Brief Process Flow
2.1. Ordinary aluminum ingot and scrap â??Melting furnaceâ?? holding furnaceâ?? 4-wheel continuous casting machine â?? front drive unit â?? roller shearsâ?? continuous rolling mill â?? cooling & lubricating device for aluminum rod â?? twin-basket continuous coilerâ?? oil-free aluminum rod
2.2. Molten aluminum or prepared aluminum melt flows from the holding furnace into the 4-wheel casting machine via the launder and is cast into trapzoid-shaped bar in a cross-sectional area of 2400mm2. Cut off the bar that does not meet the requirement for rolling with the roller shears, press the front end and feed it into the rolling mill, the rod is coiled into the basket with the coiler.
3. Main Components
This production line is composed of Melting furnace (5t/h), Twin-chamber holding furnace (28t) , 4-wheel casting machine, front drive unit, roller shears, supporting device for cast bar movement, continuous rolling mill, lubrication oil system for rolling mill, emulsion circulation system for rolling mill, cooling & lubricating system for aluminum rod, two-position coiler, and electrical control system and so on.
