The quality of cathode copper: copper concentrate by electrolytic refining method or cathode copper produced by electrolytic deposition according to GB/T467-1997 the provisions of the cathode copper cathode copper by chemical composition can be divided into high purity cathode copper (Cu – CATH – 1) and the standard of cathode copper (Cu – CATH – 2) and two brand of cathode copper test methods: high purity cathode copper chemical composition of the arbitration analysis method according to GB/T13293-1991 chemical analysis method of high purity copper anode, standard copper cathode of the chemical composition of the arbitration analysis method according to GB/T5121-1996Specification of methods for chemical analysis of copper and copper alloys for visual inspection of surface quality.
1. mainly used for melting ingot
2. discontinuous melting with scrap
3. easy control and operation
4. fast melting
5. Used for industry such as automobile, pinning and weaving, electron broadly and so on
