1480 DEG C, and furnace temperature high temperature then more than 1600 DEG C, oxygen-enriched or pure oxygen burning mode is typically employed, this will cause cast iron
During fusing, there is oxidation reflection in iron liquid with the oxygen of surplus, and iron oxide and ferrous oxide increase, while molten by increasing
It is smelt this, adjustment product quality must add carbons material as additive, does not still overcome and cause environment dirty in production process
Dye.Key is not produce any polluter in production process, and a kind of cast iron production technology and equipments are created completely.
The content of the invention
The utility model is to solve the above problems, there is provided one kind is using advanced high temperature oxygen deprivation multicell heat accumulation burning skill
Art, any additive is not increased in production process, air themperature is preheating into more than 1200 DEG C, has been recycled in stove and had been produced
A large amount of physical thermals that journey high temperature flue gas is taken out of, improve the ignition temperature of fuel, natural gas is completely in high temperature oxygen deprivation and melt
Change the state of cast iron, due to make use of production process high temperature flue gas is taken out of in stove a large amount of physical thermals so while reducing day
The consumption of right gas, reduces production cost.
Technical solution adopted in the utility model：
A kind of high temperature oxygen deprivation multicell heat accumulation founding furnace system, including high-temperature smoke discharging device, gas pipeline, multiple burners
With a casting furnace, burner point three sections of heat accumulation rooms, each two burner separation casting furnace two ends, then by docking port with it is molten
Iron furnace is docked, and the main body of blast furnace is divided into interconnected melting chamber, firing chamber and forehearth, and melting chamber top is provided with charging aperture,
Preceding furnace bottom is provided with discharging opening, and gas pipeline is communicated at the burner of each burner, and gas pipeline draws natural gas branch
To the melting chamber porch of blast furnace, melting chamber porch is provided with flame detector, and high-temperature smoke discharging device is by smoke evacuation steel on road
The heat accumulation room that steel pipe of discharging fume is communicated to each burner for air-introduced machine, three-way diverter valve is set on pipe.
Described being connected on the gas pipeline of burner sets ball valve and Pneumatic valve in burner front end.
Described high-temperature smoke discharging device is connected to burner to branch road is drawn on the pipeline of burner at three-way diverter valve,
Thermal resistance, regulating valve, air blower and pressure switch are set on branch road.
The beneficial effects of the utility model：The utility model is passed through burning by the high-temperature smoke discharging gas of high-temperature smoke discharging device
Device, air is heated by heat storage in the burner, then iron-smelting furnace is heated up by air, and breaking through gas furnace cannot melt
