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;
