Description
Technical field
The utility model relates to a kind of cleaner that is used for intermediate frequency furnace, is mainly used in the smoke gas treatment of field of metallurgy.
Background technology
Intermediate frequency furnace is a kind ofly to change more than the intermediate frequency 300Hz power frequency 50Hz alternating current into to 20K Hz supply unit; The three-phase main-frequency alternating current, become direct current after the rectification, become adjustable electric current of intermediate frequency to direct current again; Supply is by the intermediate frequency alternating current that flows through in electric capacity and the induction coil; In induction coil, produce the highdensity magnetic line of force, and the metal material that holds in the cutting induction coil, very big eddy current in metal material, produced.
This eddy current has some character of electric current of intermediate frequency equally, that is, the free electron of metal self will produce heat having in the metallic object of resistance to flow.For example; Be placed on a metal cylinder in the induction coil of alternation electric current of intermediate frequency; Metal cylinder does not directly contact with induction coil, and the hot-wire coil self-temperature is very low, but that periphery is heated to is rubescent; Even fusing, and the power that this rubescent speed with fusing needs only regulating frequency size and electric current just can realize.If cylinder is placed on hub of a spool, the temperature of cylinder periphery is the same so, and cylinder heating and fusing do not produce pernicious gas, optic pollution environment yet.
Intermediate frequency furnace is widely used in melting, Forge Heating and the heat treatment of non-ferrous metal.
Melting mainly is used in the melting of nonferrous materials such as ferrous material such as steel-smelting, steel alloy, special steel, cast iron and stainless steel, zinc, also can be used for the melting and the intensification of non-ferrous metals such as copper, aluminium, insulation, and can carry out duplex with blast furnace and move.
Forge Heating is used for bar, round steel; Square steel; Steel plate diathermanous mended temperature, the orchid online heating of blanking of quenching; Heating before the local heat, the online forging of metal material (like finish forges such as gear, semiaxis connecting rod, bearings), extruding, hot rolling, shearing, spraying heating, that hot charging is equipped with and metal material is whole is modified, annealing, tempering etc.
Heat treatment mainly supplies axle type (d-axis, multidiameter shaft, camshaft, bent axle, gear shaft etc.); The gear class; Cover, circle, dish class; Machine tool lead screw; Guide rail; The plane; Bulb; That the surface heat of multiple machinery such as hardware & tools (automobile, motorcycle) part is handled and metal material is whole is modified, annealing, tempering etc.
At present, the flue gas trapping form that contains dust of intermediate frequency furnace is main with the umbrella shape rotary cover, and the umbrella shape rotary cover is erected at the fire door top of intermediate frequency furnace; Cleaner through being arranged on outside the factory building carries out the outdoor dedusting of intermediate frequency furnace, on the one hand, and in charging and tapping; Fire door is in outside the cover mouth of rotary cover; Can't effectively flue gas be taken away, cause the flue gas that contains dust directly to be diffused in the workshop, cause environmental pollution; On the other hand, the flue gas that will contain dust within the factory building is discharged to and need be about 60～130 meters outside the factory building, and the cleaner outside the factory building accounts for the outer soil of large-area factory building, has caused equipment to build that investment is big, use cost is high.
