Nickel cobalt lithium recovery fire smelting equipment
Process specification:
Description: The nickel cobalt matte produced by the vulcanized electric furnace flows through the chute into the ladle, the ladle is moved to the LF refining position under the ladle car, and the refining begins.
productive technology:
Mechanical equipment summary:
The mechanical equipment consists of ladle and ladle car, electrode lifting device, water-cooled furnace cover and lifting mechanism, hydraulic system, nitrogen system, water cooling system, oxygen system, lubrication system and electrode lengthening station.
The structure of the equipment:
1) 3000kVA vulcanization furnace adopts the semi-closed fixed furnace type with low smoke hood;
2) The use of all water-cooled bellows pressure ring, so that the copper tile force uniform, balanced and uniform conduction;
3) The use of new water-cooled cable technology and forged copper shingles, water-cooled cable and copper pipe connection selection of button-type connection, which can reduce the contact resistance;
4) The new short network structure of one to one between the transformer outlet and the copper tile makes the equipment more advanced and the operation rate is high;
5) The short-net design uses the three-phase electrode triangle connection method, which has good short-net compensation, low impedance, low three-phase unbalance coefficient, high power factor and significant power-saving effect;
6) Full hydraulic lock, PLC control, to achieve voltage discharge, improve the operation rate of the electrode system;
7) The high-current current-carrying conductor is made of non-magnetic steel, which can greatly reduce the power loss;
