Abstract
An electric arc furnace for separating titanium from iron comprises a furnace body and a furnace cover. The furnace body is composed of an inner furnace wall and an outer furnace wall which are built through refractory bricks. A hearth is arranged in the inner furnace wall, magnesia refractory is filled between the inner furnace wall and the outer furnace wall, a precast slab made of the magnesia refractory is arranged on the top surfaces of the inner furnace wall and the outer furnace wall. The furnace over comprises a circular cover body, three round holes for three electrodes to be inserted are uniformly opened at intervals in the middle of the circular cover body, a hollow water channel is arranged in the circular cover body, and at least one water inlet and one water outlet are arranged on the top surface of the circular cover body. By means of the electric arc furnace for separating titanium from iron, not only the production cost is reduced, but also as no asphalt is dissolved in the furnace, the working environment is improved greatly, and the problem of pollution of asphalt fume to the surroundings is solved.
Description
Technical field
The utility model relates to a kind of electric arc furnaces for smelting the ferrotianium separation, particularly relates to a kind of ferrotitanium dispersing arc furnace.
Background technology
High too slag is that sulfuric acid process and chloridising are produced too white raw material, also is the raw material of producing the series of products such as titanium tetrachloride and titanium sponge.Ilmenite is the raw material of producing high titanium slag, and China is titanium resource big country, accounts for 45% of world saving, and the main method of producing at present high titanium slag both at home and abroad is reducing smelting process.The method is with electric arc furnaces furnace charge to be heated up, and is heated to the high temperature about 2000 degree, and the recovery time that at high temperature keeps a fixed length, and titanium and iron are separated.It is take anthracite or oil as reducing agent, and gained condensed state product is the pig iron and high titanium slag, its essence is that ilmenite and solid reductant etc. mix to add to carry out reduction melting in the electric arc furnaces, and the oxidation of iron selectively is reduced to metallic iron in the ore deposit.And titanyl compound is enriched in the slag.In the prior art, the upper port of electric arc furnaces is opened wide during with electric arc furnaces smelting reducing ferrotianium, because electric arc furnaces does not have special-purpose arc furnace cover,
With electric arc furnace smelting separating titanium iron ore the time, in order to be incubated in the stove, often at ilmenite powder with contain and add a certain amount of pitch in the reducing agent furnace charge of fixed carbon, during the electric arc furnaces heating, particularly interior at high temperature in advance dissolving, volatilization, the burning of pitch of bottom furnace charge of pitch in the furnace charge, produce a large amount of glance coals, the fluorescent material in the glance coal, carcinogen also come up from electric arc fire door spray with pitch cigarette ash, the environment around not only having brought harm but also severe contamination to health of human body.In addition, because electric arc furnaces does not have bell, make the interior heat-insulating property of stove bad, be difficult for making the temperature in the stove to reach ferrotianium separation temperature and recovery time, greatly prolonged the duration of heat, not only waste energy, and reduced product quality.
The utility model content
The purpose of this utility model is defective and the deficiency that exists for overcoming above-mentioned prior art, and a kind of environment-friendly type ferrotitanium dispersing arc furnace is provided.
The technical scheme that adopts is:
A kind of ferrotitanium dispersing arc furnace, comprise body of heater, bell, described body of heater is made of the inner furnace wall that is built into refractory brick and outer furnace wall, be burner hearth in the inner furnace wall, be filled with magnesia refractories between inner furnace wall and the outer furnace wall, be provided with the prefabricated board of being made by magnesia refractories on the end face of inner furnace wall and outer furnace wall, there is the circular port that inserts for three electrodes at the middle part of prefabricated board, described bell, comprise circular lid, the interval, middle part of described circular lid offers uniformly three power poles and inserts circular hole, is provided with cavity water channel body in the circular lid, is provided with at least an inlet opening and an apopore on the end face of circular lid.
The utility model is owing to installed intensity and the higher bell of compaction rate at electric arc furnaces, thereby, have the advantages such as resistance to elevated temperatures is good, good heat insulating, long service life, can in producing, use by many stoves, in the ferrotianium separation of produced, owing to increased bell, ferrotianium separation temperature and maintenance recovery time have greatly been shortened, and then reduced energy consumption, and improved the quality of product.In addition, because the uncovered usefulness at electric arc furnaces top bell sealing of the present utility model, thereby has a preferably heat insulation effect, the furnace charge that adds in the stove can all participate in the melting separation in melting once, greatly improved single furnace output, simultaneously, because high insulating effect, so that electric arc furnaces when smelting the separating titanium iron ore at ilmenite with contain in the reducing agent furnace charge of fixed carbon and need not add pitch, not only reduced production cost, and because there not being pitch prill in stove, to dissolve, greatly improved work situation, solved the pollution problem of glance coal to surrounding environment.
