Description
Technical field
The present invention relates to metallurgical technology field, particularly the energy-conservation corundum smelting stove of one.
Background technology
At present, the smelting of corundum mainly adopts dumping furnace, its general principle is: the body of heater of dumping furnace is by trunnion support, first in body of heater, add bauxite or the formula materials such as alumdum and other reducing agent, then, electric current is sent into by three electrodes, make load melting in body of heater and with the reactions such as reducing agent, after question response terminates, be loaded on the gear on gudgeon by machine driving, gudgeon is rotated, thus drive tilting furnace, high-temperature fusant in stove is poured into be connect in bag, obtains corundum product.
Due to the design feature of dumping furnace self, make it in corundum smelting process, have following inevitable defect:
1. at the end of smelting, the corundum melt of temperatures as high 2000 degree pours down from the height of more than 5 meters, and can dock contracts for fixed output quotas gives birth to serious impact, very easily overflows burning apparatus;
2., owing to being subject to the restriction of transmission mechanism and body of heater deadweight, the flame retardant coating thickness low LCL of body of heater, thus has following drawback:
(1) in smelting process, the normal melt that occurs burns flame retardant coating, causes high-temperature fusant to spill, burns the accident of water-cooling system and equipment, and in addition, high-temperature fusant meets water also can cause heavy explosion, causes casualties, the accident of equipment, factory building damage;
(2) flame retardant coating of body of heater is thick not, and furnace wall needs water cooling, and cooling water can take away a large amount of waste heat, is unfavorable for energy-conservation;
3. can not continuous seepage, from blowing out to the off time of blow-on again more than one hour, the high-temperature residual heat in stove runs off in a large number, and be unfavorable for energy-conservation, utilization rate of equipment and installations is low;
4., at every turn to before connecing in bag and toppling over high-temperature fusant, electrode all needs lift-off bell, easily burns the accident of short net;
5. at every turn to connect in bag topple over high-temperature fusant time, the part alumina etc. remained on fire door all can be had to connect in bag along with high-temperature fusant is poured into, affect the quality of product.In addition, method of banishing is smelted and is produced corundum and be just once suggested as far back as the seventies in last century, but due to features such as the high-melting-point of corundum, high strength and trickling differences, method of banishing is produced for the smelting of corundum and failed to realize always.
