Cathode copper/Scrap copper → melting furnace → transition chamber → holding furnace → casting machine (crystal molding) → casting rod → take-up device → on sale or further producing
Put the cathode copper into the melting furnace of QL1 compounded furnace straightly. It will be melted into liquid by a frequency inductor. Then the liquid of copper smoothly pass through the transition chamber and will flood into the holding furnace automatically , and then it will be deoxidized by the charcoal covered. The liquid of copper will become a casting rod quickly by the crystallizer of the casting machine in the holding furnace. Then it will be hauled by the double-withdrawal roller of the casting machine. When the casting rod is hauled off, it will be led to take-up device.
