Oxygen Free Copper Rod Continuous Up-Casting Line & Cold Rolling Mill
I Process Specification
Put copper cathode over the furnace by the lifting system for baking→Adjust the feeding speed according to the casting speed. Feed the copper cathode into the melting furnace for melting (charcoal to be used for avoiding oxidization) → copper liquid flows into the transition part (charcoal is still needed to avoid oxidization) → Copper liquid flows into the holding furnace → Copper liquid flows into the crystallizer to be copper rods → copper rods enter into traction device for upward movement → Go through the output frame →copper rods go through the output frame (to separate each rod) → copper rods go through the tension frame ( to control the take-up speed) → copper rods go through the take-up machine,for coiling → Next process

III Other explanation
1. Requirement of raw material: 99.97% copper cathode
The surface of the copper cathode should be clean, and there should be no electrolyte or greasy substance.
There should be no "copper bean", if there is any, it must be removed . Both the surface and the edge should be smooth.
If there is no mechanical feeding device for equipment, copper materials should be cut into small pieces for easy feeding.
2. Requirements of charcoal
High-quality white charcoal (commonly known as steel charcoal, pear charcoal)
Water content: 0.5~1%
Other volatiles: ≤5%
Charcoal particle size: 30~70mm
Not allow sulfur, iron and charcoal had no calcination
Fracture should be shiny, white light, sound crisp when breaks .
Consumption:5kg/ton
3. Requirements of graphite flake
Specification: 3299 or 5099
Granularity: 32 or 50
Require natural graphite flake
Consumption: 0.5kg/ton
