Description
Technical field
The present invention relates to metallurgical technology field, particularly one banishes method corundum smelting stove.
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, all the part alumina etc. remained on fire door 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.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind ofly can realize working continuously, method of the banishing corundum smelting stove of Automated condtrol, job safety.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: one banishes method corundum smelting stove, comprises body of heater, is provided with furnace chamber in described body of heater, is provided with electric heater unit in described furnace chamber; Be horizontally disposed with plugging hole in the middle part of the sidewall of described body of heater, described plugging hole is communicated with described furnace chamber; The lower end of described plugging hole is provided with banishes hole, described one end of banishing hole is communicated with described plugging hole, described plugging hole is provided with blocking plunger away from one end of described furnace chamber, one end of described blocking plunger is stretched in described plugging hole, and can move horizontally in described plugging hole, the other end of described blocking plunger is connected with thrust unit, described thrust unit can promote described blocking plunger move horizontally in described plugging hole and convection current discharge hole block; Described another port of banishing hole is tilted to down and is communicated to outside described body of heater, describedly banish the below that hole is communicated to port outside described body of heater and be provided with guiding gutter, described guiding gutter is downward away from the lopsidedness of described body of heater, and the below correspondence that described guiding gutter is tilted to lower side is provided with and movably connects bag.
The invention has the beneficial effects as follows: raw material is put into furnace chamber, electric heater unit heats, and realizes smelting, and the high-temperature fusant after smelting is by plugging hole and banish hole releasing, is flowed into connect in bag by guiding gutter; Connect the impact that bag effectively can cushion high-temperature fusant, thrust unit effectively can control blocking plunger and move horizontally in plugging hole, thus realize controlling high-temperature fusant and be drained to and banish hole, and the degree of depth of plugging hole is goed deep into by controlling blocking plunger, thus control the flow of high-temperature fusant, can adjust the impact of high-temperature fusant docking bag, avoid high-temperature fusant spilling burning apparatus, realization is worked continuously, Automated condtrol, job safety.
On the basis of technique scheme, the present invention can also do following improvement.
Further, it is cylindric that described blocking plunger is in part in described plugging hole, and the cross section that described blocking plunger is in part in described plugging hole is greater than the cross section that described blocking plunger is in the outer part of described plugging hole.
The beneficial effect of above-mentioned further scheme is adopted to be: can effectively prevent high-temperature fusant from being overflowed by plugging hole.
Further, described blocking plunger is made up of carbon composite.
The beneficial effect of above-mentioned further scheme is adopted to be: the intensity of carbon composite energy lifting blockage post, extends the service life of this device.
