Abstract
The utility model belongs to the electrometallurgy equipment adopted in electric steel-smelting, relating to a new type of steel-smelting furnace. The steel-smelting furnace is characterized in that it is a combined furnace composed of a smelter, a coal furnace, an oil furnace and a dust chamber, the smelter is an upright cylindrical structure with a disk-shaped base at the bottom, one side of the smelter is connected with the coal furnace and the other side is connected with the oil furnace, the disk-shaped base is connected with a checker chamber, and the dust chamber is arranged between the checker chamber and an air flue. The new type of steel-smelting furnace of the utility model is novel in structure, which uses coal as the major fuel and smelts the steel by the elevated temperature produced by the cyclic heating of oil and oxygen, so that the energy, electricity, oil and coal can be saved. The utility model has the advantages of little equipment investment, small ground occupying, short steel-smelting time, fast melting speed, high yield, low cost, convenient manipulation and no environment pollution. The reliable steel supply for all sorts of architectural materials can be realized by adopting this steel-smelting furnace.
Description
Technical field
The utility model belongs to the electrometallurgy equipment that adopts Electric furnace steel making, relates to a kind of novel steel melting furnace.
Background technology
Since the early fifties oxygen top blown converter steel making dropped into suitability for industrialized production, great variety had taken place in the steel-making industry, and open hearth will be eliminated, and oxygen converter steelmaking suffers with steel scrap to be the challenge of the Electric furnace steel making of main furnace charge.Electric furnace steel making is the firm main means of production high-quality all the time, but the problem that existence yields poorly, power consumption is big, tap to tap time is long, production cost is high.
Summary of the invention
The purpose of this utility model is for overcoming the shortcoming of above-mentioned existence, provides that a kind of speed of melting is fast, output is high, save energy, a kind of novel steel melting furnace free from environmental pollution.
A kind of novel steel melting furnace content Description of the utility model:
A kind of novel steel melting furnace of the utility model, it is characterized in that: be to be combined into a kind of combination stove by smelting furnace, coal stove, oil oven, dust settling chamber, smelting furnace is a vertical type cylinder shape structure, and the bottom is provided with disc-shaped base, one side of smelting furnace is connected with coal stove, and opposite side is connected with oil oven and links together; Disc-shaped base is connected with regenerator, in the centre of regenerator and flue dust settling chamber is set.
A kind of novel steel melting furnace of the utility model, its novel structure, be to be main fuel with the coal, and add the steel-making of thermogenesis high temperature with oil, oxygen circulation, save energy, power saving, fuel-efficient, economize coal, have that facility investment is few, floor space is little, the steel-making time is short, speed of melting is fast, output is high, cost is low, characteristics of easy to operate, non-environmental-pollution.Adopt the utility model steel melting furnace to can be various material of construction and provide reliable for ingot.
Description of drawings
Fig. 1 is a kind of novel steel melting furnace structural representation
Among the figure: 1 is that smelting furnace, 2 is that coal stove, 3 is that oil oven, 4 is that dust settling chamber, 5 is that base, 6 is that regenerator, 7 is a flue.
Embodiment
A kind of novel steel melting furnace of the utility model is to realize like this, specify below in conjunction with accompanying drawing, see Fig. 1, a kind of novel steel melting furnace of the utility model is the principle according to openhearth steelmaking, adopt the advantage of blast furnace, open hearth, reverberatory furnace, cupola furnace, converter, oil oven, based on coal, oil, oxygen circulation, generation high temperature is made steel.Be to be combined into a kind of combination stove by smelting furnace 1, coal stove 2, oil oven 3, dust settling chamber 4, smelting furnace 1 is a vertical type cylinder shape structure, and the bottom is provided with disc-shaped base 5, and a side of smelting furnace 1 is connected with coal stove 2, and opposite side and oil oven 3 link together; Disc-shaped base 5 is connected with regenerator 6, in the centre of regenerator 6 and flue 7 dust settling chamber 4 is set.Coal-fired in coal stove 2 internal combustion, heat is melting the steel scrap in the smelting furnace 1, ore, molten steel flows in the oil oven 3, pass through fuel heating, temperature is increased to 1400～1500 ℃, molten steel after the fusing heats in oil oven 3, and temperature reaches 1700～2200 ℃ once more after the melting, and molten steel flows out from oil oven 3 fire doors casts.The base 5 of smelting furnace 1 bottom is connected with regenerator 6, and inner flue gas of the stove enters flue, non-environmental-pollution through dust settling chamber 4.The utility model speed of melting is fast, went out one heat steel in 1.5 hours, can replace electric furnace, openhearth steelmaking, produces various steel castings.
