Description
Technical field
The utility model is related to metallurgical technology field, more particularly to a kind of high temperature oxygen deprivation multicell heat accumulation casting furnace.
Background technology
When the preceding technological requirement that the metals such as melting iron cast steel are not reached because of natural gas fired incinerators temperature, the metal molten such as cast iron
It is substantially all and uses the furnace cupola with coke as fuel and the electric furnace with electricity as energy consumption to be melted.The production efficiency of furnace cupola
Low, energy consumption is big, and environmental pollution is serious, and product quality is low, and country has cancelled review batch construction furnace cupola, and forbids 10 tons
Following furnace cupola reproduction, and in addition to the production cost that furnace melting is caused except power consumption is high is high, firepower is also increased indirectly
The environmental pollution that power plant coal burning is caused.
Casting furnace is studied and is applied and be all confined to ordinary combustion, oxygen-enriched combusting, the former does not break through high temperature production demand,
The latter influences product quality, therefore cannot all be applied in numerous areas and enterprise, and it is clean that this constrains natural gas to a certain extent
The extensive use of the energy, also remains high in production field entreprise cost.
The content of the invention
The utility model is to solve the above problems, there is provided, with natural gas as fuel, heating-up temperature is up to 1600 DEG C for one kind
The casting furnace of high-temp combustion above.
Technical solution adopted in the utility model：
A kind of high temperature oxygen deprivation multicell heat accumulation casting furnace, including body of heater, burner hearth and the burner that is connected with body of heater, the stove of body of heater
Wall ecto-entad is followed successively by steel construction, heat insulating board and insulating brick, and castable, described stove are filled between burner hearth and insulating brick
Thorax is divided into three Room, the respectively forehearth of the melting chamber on upper strata, the firing chamber in middle level and bottom, and upper of furnace body is charging aperture, forehearth
Bottom be provided with discharging opening, discharging opening extends to bottom of furnace body through castable, and described burner is segmentation heat accumulation burner,
Two burners are docked at body of heater both sides, and burner is provided with each burner and body of heater docking port, are passed through body of heater and burner
Air pipeline is connected with burner.
Exhaust gas and natural gas are alternately discharged and are passed through by reversal valve from body of heater in described air pipeline.
Three sections of heat accumulation rooms of described burner point, heat accumulation chamber interior walls set heat storage, and heat accumulation room is connected with air pipeline.
The beneficial effects of the utility model：Smoke discharging in the utility model is passed through burner, heat by air pipeline
It is stored in heating air in burner and improves temperature in burner hearth again, form the burning situation of high temperature oxygen deprivation, improves combustion system heat
Ironmaking quality is improved while efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- burners；2- castables；3- melting chambers；4- firing chambers；5- heat insulating boards；6- insulating bricks；Before 7-
Stove；8- steel constructions；9- charging apertures；10- discharging openings.
Specific embodiment
A kind of high temperature oxygen deprivation multicell heat accumulation casting furnace, including body of heater, burner hearth and the burner 1 that is connected with body of heater, body of heater
Furnace wall ecto-entad is followed successively by steel construction 8, heat insulating board 5 and insulating brick 6, and castable 2 is filled between burner hearth and insulating brick 6,
Described burner hearth is divided into three Room, the respectively forehearth 7 of the firing chamber 4 of the melting chamber 3, middle level on upper strata and bottom, and upper of furnace body is
Charging aperture 9, the bottom of forehearth 7 is provided with discharging opening 10, and discharging opening 10 extends to bottom of furnace body, described burning through castable 2
Device 1 is segmentation heat accumulation burner, and two burners 1 are docked at body of heater both sides, and burning is provided with each burner 1 and body of heater docking port
Mouth, the air pipeline for being passed through body of heater and burner 1 is connected with burner.
Exhaust gas and natural gas are alternately discharged and are passed through by reversal valve from body of heater in described air pipeline.
Described three sections of heat accumulation rooms of burner 1 point, heat accumulation chamber interior walls set heat storage, and heat accumulation room is connected with air pipeline.
The exhaust gas for having 1600 DEG C in body of heater are passed through burner 1, the heat storage of exhaust gas in heat storage, Xiang Ran
The air being passed through in burner 1 is heated to more than 1200 DEG C, and exhaust gas are cooled to 100 DEG C or so, and air mixes with natural gas,
Lighted by burner, be transported to for remaining flue gas heat as supplemental heat in burning by exhaust gas by air, and raw material is molten
Change room 3 is primary melting, and then reheating chamber 4 further lifts the quality that temperature improves melting, and the feed liquid refined is again from forehearth 7
10 mouthfuls of discharging outflow.
One embodiment of the present utility model has been described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to present utility model application scope
Impartial change with improve etc., all should still belong within patent covering scope of the present utility model.
