Abstract
The invention relates to an energy-saving steel refining furnace, which is characterized in that the energy-saving steel refining furnace is a combined furnace consisting of a smelting furnace, a coalfurnace, an oil furnace and a dust removal chamber, wherein the smelting furnace has a vertical cylindrical structure, the bottom of the smelting furnace is provided with a disc base, one side of thesmelting furnace is connected with the coal furnace, the other side of the smelting furnace is connected with the oil furnace together, the disc base is connected with a heat accumulation chamber, and the dust removal chamber is arranged between the heat accumulation chamber and a flue. The energy-saving steel refining furnace has a novel structure, uses coal as a main fuel and uses oil and oxygen circular heating to produce high-temperature refined steel so as to save energy, electricity, oil and coal, and has the characteristics of less equipment investment, small occupied area, short steelrefining time, high smelting speed, high yield, low cost, convenient operation and environmental protection. The steel refining furnace can provide reliable ingots for various building materials.
Description
Technical field
The invention belongs to the electrometallurgy equipment that adopts Electric furnace steel making, relate to a kind of energy-saving 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 scrap iron to be the challenge of the Electric furnace steel making of main furnace charge.Electric furnace steel making is the main means of production high-quality steel 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 objective of the invention is for overcoming the shortcoming of above-mentioned existence, provide that a kind of speed of melting is fast, output is high, save energy, a kind of energy-saving steel melting furnace free from environmental pollution.
A kind of energy-saving steel melting furnace content Description of the present invention:
A kind of energy-saving steel melting furnace of the present invention, 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, the bottom is provided with disc-shaped base, one side of smelting furnace is connected with coal stove, opposite side and oil oven link together, and disc-shaped base is connected with regenerator, in the centre of regenerator and flue dust settling chamber are set.
A kind of energy-saving steel melting furnace of the present invention, 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 steel melting furnace of the present invention to can be various material of construction and provide reliable for ingot.
Description of drawings
Accompanying drawing is a structural representation of the present invention;
Among the figure, 1 smelting furnace, 2 coal stoves, 3 oil ovens, 4 dust settling chambers, 5 bases, 6 regenerator, 7 flues.
Embodiment
A kind of energy-saving steel melting furnace of the present invention is to realize like this, specify below in conjunction with accompanying drawing, see accompanying drawing, a kind of energy-saving steel melting furnace of the present invention 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, the bottom is provided with disc-shaped base 5, one side of smelting furnace 1 is connected with coal stove 2, 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, steel scrap, ore that heat will hold in the furnace 1 are melting, 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.Speed of melting of the present invention is fast, went out one heat steel in 1.5 hours, can replace electric furnace, openhearth steelmaking, produces various steel castings.
