8mm copper rod upcasting production line
Process Specification
Copper cathode to be put on the furnace through the lifting system for baking→Ajust the feeding speed according to the casting speed. Feed the copper cathode into the melting furnace for melting (charcle to be used for avoiding the oxygen) → Flow into the transition part (charcle still need to be used for avoiding the oxygen) → Flow into the holding furnace → Flow into the crystallizer, and the copper rods come out → Flow into the casting device → Go through the output frame →Go through the separate shelf (to separate each rod) → Go through the tension tower ( to contrl the take up speed) → Go through the take up machine, and finish coiling → Next process

One ton copper rod need:
Electricity: ≤400 KWH/T
Charcoal 8~10Kg（for melting furnace and transitional chamber）
Graphite powder ~1Kg (for holding furnace). If using charcoal, the dosage will be about 4kg.
Others：Buyer uses bright wasted wire and cable, small copper scrap as raw material.
Output will be reduced by this raw material. The lower oxygen content and resistance ratio, the smaller influence to product. If buyer uses this raw material, we can not guarantee the resistance and conductivity.
Consumption will be increased if using this material.
Charcoal must be used for holding furnace if using this material.
