Description
Technical field
The utility model relates to a kind of blast furnace apparatus for baking that is mainly used in newly-built blast furnace and blast furnace overhaul.
Background technology
The iron-smelting blast furnace body is to be welded into the stove skin by steel plate, and its inboard hangs with the water flowing cooling stave, and the cooling stave inboard is built refractory materials by laying bricks or stones, and generation blast furnace life is more than 15 years.The liner of blast-furnace body contains a large amount of moisture content in refractory materials and the mortar in building process, and blast furnace production just is in the pyritous Working environment from the beginning of going into operation always, is the encloses container of a long term high temperature job, and will keeps temperature stably as far as possible.In order to make inner lining refractory adapt to smelting environment in the State of Blast Furnace as early as possible, and given play to the effect of protection blast-furnace body, before high furnace igniting, blast furnace must carry out the baker operation, with the most moisture content on the thorough removal body, makes the blast furnace operation of lighting a fire smoothly.Blast oven is the hot blast that blows into from the air port by the hotblast stove heating, utilizes the temperature of hot blast, gradually the moisture content in the body is heated up, and finally drains from venting hole and Blast Furnace Throat Ventilation Valve with the form of water vapour.Generally speaking, blast oven needs 10-15 days, comprising intensification, insulation, several stages again heats up, is incubated, lowers the temperature, baker cools at last, when the inlet front end temperature drops to 100 ℃ of left and right sides in the stove, stop to be blown into hot blast, use instead and be blown into natural wind blast furnace is cooled down.The emphasis of baker is cupola well, furnace bottom, otherwise emit a large amount of steam after the blow-on, not only can absorb the cupola well heat, reduce slag iron temperature, make the start-up of the furnace difficulty, and the moisture rapid evaporation, a large amount of steam are run out of from brickwork joint, may make bricking cracking and furnace expansion and be damaged, influence blast furnace campaign.Therefore, the quality of blast oven has very big influence to the life-span of blast furnace.
At present, the blast oven temperature that generally adopts gas blower by hotblast stove air-supply cold wind to be heated to regulation is sent into the mode of blast furnace by the air port.Old-fashioned furnace drying device is to adopt 1/3rd air ports to connect the baker pipe to reach in the cupola well, 2/3rds air ports directly are blown into the mode baker of hot blast, its shortcoming is that the cupola well heating is inhomogeneous, heat does not arrive cupola well and has directly run away from furnace roof by shaft, cause cupola well not heat up effectively, 10-15 days bakers finish the back blast furnace hearth and do not dry by the fire, and furnace bottom carbon brick temperature has only about 70 ℃, illustrates that some water does not evaporate.
Summary of the invention
The purpose of this utility model provides a kind of blast furnace apparatus for baking, and it is inhomogeneous to solve the heating of old-fashioned apparatus for baking cupola well, and the moisture of anti-material and brickwork joint is the problem of evaporation fully not.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of blast furnace apparatus for baking is characterized in that blast pipe feeds cupola well from the air port, and the outlet of blast pipe is at the cupola well center, and is inserted into furnace bottom, and blast pipe top is provided with round iron plate, and exhaust duct inserts iron notch.
The outlet of described blast pipe be arranged on diameter be 1/3 cupola well diameter with the concentric circumference of cupola well on.
The outlet of described blast pipe be arranged on diameter be 2/3 cupola well diameter with the concentric circumference of cupola well on.
Circumferential direction every interval in described air port is provided with a thermometric galvanic couple for 120 °.
Compared with prior art, the beneficial effects of the utility model are: this apparatus for baking can satisfy the requirement of blast oven, make the blast furnace hearth even heating, furnace bottom carbon brick temperature reaches more than 100 ℃, the whole blast furnace moisture of anti-the material is evaporated fully, simple in structure, reliable, can reuse, reduce facility investment, satisfy requirement newly-built, the overhaul blast oven.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
With reference to accompanying drawing 1, accompanying drawing 2, a kind of blast furnace apparatus for baking, blast pipe 2 is 6 feeding cupola wells 1 from the air port, the outlet of blast pipe 2 is at cupola well 1 center, and be inserted into furnace bottom, and blast pipe 2 tops are provided with round iron plate 3, and exhaust duct 4 inserts iron notch 5, slit refractory materials tamping between itself and the iron notch 5, hot blast is discharged from exhaust duct 4 during blast oven.Blast pipe 2 outlet also be arranged on diameter be 1/3 cupola well, 1 diameter with cupola well 1 concentric circumference on.Blast pipe 2 outlet also be arranged on diameter be 2/3 cupola well, 1 diameter with cupola well 1 concentric circumference on.6 circumferential directions every interval in air port is provided with a thermometric galvanic couple 7 for 120 °.
During installation, unload next air port 6 little covers from blast furnace hearth 1, the operating personnel can enter in the blast furnace hearth 1.Blast pipe 2 is sent in the stove from blast-furnace tuyere 6, in stove, be welded into "
" shape, one is inserted 6, one in air port and inserts cupola well 1; be fixed on furnace bottom with angle bar frame, and blast pipe 2 outlets are 1.5 meters with the distance of anti-material at the bottom of the State of Blast Furnace, and all the other half blast pipes 2 are apart from 2 meters of cupola well 1 sidewalls; generally apart from 4 meters of cupola well 1 sidewalls, and two kinds of specification pipes intert mutually to be opened.Diameter also 6 is sent in the stove from the air port less than the round iron plate 3 of 1 meter of cupola well diameter, welding assembly in stove, and round iron plate 3 is welded on the blast pipe 2 round iron plate 3 plaies when preventing baker.Insert exhaust ducts 4 from blast furnace iron notch 5, slit refractory materials tamping between itself and the iron notch 5.Hot blast is discharged from exhaust duct 4 during blast oven.Evenly choose three direction air ports 6 and insert thermometric galvanic couple 7, receive on the baker instrument, be used for observing wind-warm syndrome to change.When blast furnace overhaul, thermometric galvanic couple 7 can use the original throat temperature of blast furnace, furnace throat temperature, temperature of the furnace hearth, bottom temperature galvanic couple.
During blast oven, start gas blower, heat the wind-warm syndrome that reaches regulation through hotblast stove and send into blast furnace hearth 1 by hot air duct, blast pipe 2, hot blast is blown at the bottom of the State of Blast Furnace by blast pipe 2, upwards stop again through round iron plate 3, the hot blast secondary distribution is to blast furnace hearth 1, diffuses from blast furnace furnace roof and exhaust duct 4 to blow out.
