Description
Technical field
The utility model proposes a kind of electromagnetic induction slag smelting furnace porous revolver magazine formula mouth of a river, belong to slag melting equipment technology field.
Background technology
The process energy consumption of blast furnace ironmaking accounts for 60% of steel and iron industry total energy consumption, is the energy consumption rich and influential family of steel and iron industry, and its energy-saving and emission-reduction have a high potential.Blast furnace slag is a kind of solid waste that blast furnace ironmaking gives off, and not only consumes a large amount of energy in its processing procedure, also discharges a large amount of harmful substances simultaneously.Therefore, the research of carrying out blast furnace slag recycling aspect is very necessary, a kind of industrial solid wastes of blast furnace slag.The slag of discharging in blast furnace ironmaking process, claims again blast-furnace cinder, can be divided into conversion pig slag, foundry iron slag, ferromanganese ore slag etc.The states such as China and the Soviet Union are used titanomagnetite ironmaking in some areas, discharge vanadium titanium blast furnace slag.According to grade of ore difference, 1 ton of iron of every refining is discharged 0.3～1 ton of slag, and the grade of ore is lower, and bed drain purge is larger.China approximately discharges more than 2,000 ten thousand tons at present every year.Slag is thrown meeting land occupation aside, waste resource, contaminated environment.Within 1589, Germany start to utilize blast furnace slag.After mid-term in 20th century, blast furnace slag comprehensive utilization develops rapidly.Many countries such as the current U.S., Britain, Canada, France, the Federal Republic of Germany, Sweden, Belgium have all accomplished deslagging then, are finished then, have all realized resource.Japan's utilization rate in 1980 is 85%, and Soviet Union's utilization rate in 1979 is more than 70%, and China's utilization rate in 1981 is 83%.
Blast furnace slag is the refuse of discharging from blast furnace while smelting the pig iron, when furnace temperature reaches 1400-1600 ℃, furnace charge melting, the ash content in gangue, coke in ore and cosolvent and other can not enter impurity in the pig iron and form take silicate and aluminate as the main slag floating over above molten iron.In blast-furnace cinder, main chemical composition is SiO

3account for the more than 90% of weight.
The slag stream that mineral wool is jetted very thin with compressed air or high steam, can produce mineral wool, mineral wool can be used as insulation material, sound-absorbing material and fire proofing material etc., by the finished product of its processing, has warming plate, insulation quilt, heat-preservation cylinder, insulation belt, abatvoix, narrow felt rug, sound-absorbing band, refractory slab and heat resistance fiber etc.Mineral wool is widely used in the departments such as metallurgy, machinery, building, chemical industry and traffic.
Directly winding-up blast furnace cinder, technique is simple, invest less, but slag wool difficult quality guarantee.Take slag as primary raw material, add silica, basalt, andesite, sometimes also can add the adjustment compositions such as lime, then blowing after fusing, can obtain high-quality mineral wool.Many countries are all at operating mine slag wool.In addition, blast furnace slag also can be used as the raw material of cast stone, devitrified glass, fertilizer, enamel, pottery etc.
The method of operating mine slag wool has two kinds of blowing process and centrifugal process.Raw material flows out after melt in furnace, with steam or compressed air spraying, becomes the method for mineral wool to be called blowing process.Raw material drops on rotating disk after melt in furnace, and the method for making mineral wool with centrifugal force is called centrifugal process.
The primary raw material of mineral wool is blast-furnace cinder, accounts for 80%～90%, also has 10%～20% dolomite, fluorite or other as common brick head, cobble etc., and the fuel of operating mine slag wool is coke.Produce a point batching, fusing winding-up, 3 operations of packing.Mineral wool melting equipment is comprised of smelting furnace (furnace cupola or combustion gas tank furnace etc.), feeder, four roller centrifuges etc. conventionally.
Conventionally the technique of operating mine slag wool is dry slag to be melt into its method of liquid slag as follows:
1) pulverized fuel and raw material are burnt in helical form turbulent gases, generate silicate melt, and then silicate melt is configured as to mineral wool fiber.Raw meal ash or slag are spurted into burning gases highest temperature zone.Raw material proportioning is: every 100 parts of fine coal, and 50-300 parts of mineral wool raw materials, mineral wool raw materials has also been added 3-9% fine-powdered acidity in addition.
2) coke smelting furnace (furnace cupola).
3) combustion gas tank furnace, tank furnace refractory material laying, is entered right gas blowout in pond, to melt slag charge by spray gun.
4) metal electrode arc-melting slag charge (small-sized).
The blast furnace warm sludge that accounts for 80%～90% is directly filled to people's electromagnetic induction slag smelting furnace (15t-20t slag), also have 10%～20% dolomite, fluorite or other are if the ore charges such as common brick head, cobble are as additive, heating to 1550 degree left and right adjusts slag composition and in skull melting furnace, guarantees melt constant temperature, for subordinate's operation provides the slag of high-temperature liquid state flow-controllable, flowing, is the key technology of producing high-quality mineral wool.
The slag stream of controlled constant flow is the key that subordinate's blowing process and centrifugal process are produced high-quality mineral wool, and holding furnace bottom is thicker, has the factors such as a long section mouth of a river temperature is lower, and melted gangue meeting blocking channel, more can not control the flow that high temperature slag flows.
High-temperature slag is solidifying pasty state, its mobility extreme difference cooling to 1300 about degree.
Summary of the invention
