2.6 Maximum operating power:                270--290KW
2.7 Water consumption:                      29 tons /hour (move in cycle)
2.8 One ton copper rod need:
2.8.1 Electricity:                          ≤400 KWH/T
2.8.2 Charcoal                            8~10Kg(for melting furnace and transitional chamber)
4Kg (for holding furnace).
2.9 Others:Buyer uses bright wasted wire and cable, small copper scrap as raw material.
2.9.1 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.
2.9.2 Consumption will be increased if using this material.
2.9.3 Charcoal must be used for holding furnace if using this material.
3. Upward Casting Machinery Performance of copper rod:
3.1 Casting rod is made of standard cathode copper
3.1.1 Density:                                ~ 8.9kg/dm3

(tested after processing to3mm or 2.6mm)
3.1.5 Oxygen content:                          ≤ 10PPM
3.2 Casting rod is made of bright wasted wire and cable, small copper scrap:
3.2.1 Performance of copper rod depends on raw material.
3.2.2 Resistance is not guaranteed.
3.2.3 Meet the requirements of drawing wire.
4. Raw materials and auxiliary material:
4.1 Technical requirement of raw material:
4.1.1Technical requirement of cathode copper:
Because upward casting system only melt and cast, it can't smelt with copper. In order to guarantee the quality of light oxygen-free copper, cathode copper must fit standard GB/T467-1997. The Cu +Ag can 't be less than 99.95.
4.1.2 Technical requirement of bright wasted cable and wire, small copper scrap:
The material must be bright. It can't include the impurity such as oxide, plastic, iron, tin, al and so on. Bright wasted cable and wire must be packed.
4.2 Auxiliary material:
4.2.1 Charcoal:  used on liquid's surface of holding furnace or melting furnace, it requires better sapwood (steel charcoal, plough charcoal). Its technical requirement as following:
water content: 0.5~1% other volatile: ≤5%
It is not allowed that wooden block , sulfur and iron are included.
The granularity of charcoal is 30-70mm.
4.2.2 Graphite powder: used for cover of liquid's surface of holding furnace
Type:                    3299
Requirement of granularity:   32
Requirement of quality:      natural graphite powder
4.2.3 The requirement for the quality of cooling water should be suitable with Chinese national standard GB1576-2001 water standard of industry boiler.
Suspended substance: mg/L≤5
Total water hardness: mmol/L″≤ 0.03
PH: (25℃) ≥7.
