Abstract
The utility model discloses an induction furnace capable of blowing inert gases towards the inside of the furnace, which comprises a furnace body (1) and a furnace lining (5), wherein 1-5 ventilating bricks (2) are embedded at the bottom of the furnace lining (5); the height of each ventilating brick is equal to or slightly higher than the thickness of the furnace lining at the bottom; inert gas conveying pipe through holes with the same quantity as that of the ventilating bricks (2) are arranged at the bottom of the furnace body (1); an inert gas conveying pipe (3) is arranged at the lower part of the ventilating bricks (2), and extends out of the bottom of the furnace body (1) through the inert gas conveying pipe through holes to be communicated with an inert gas source; and a layer of ventilating lining (6) is tamped at the upper part of the furnace lining at the bottom and the ventilating bricks (2) respectively. The induction furnace capable of blowing inert gases towards the inside of the furnace has the service life up to hundreds of heats.
Description
Technical field
The utility model relates to a kind of induction furnace, especially a kind of can be in stove the induction furnace of blown inert gas.
Background technology
For improving steel product quality, steel mill has adopted BOTTOM ARGON BLOWING refining techniques in outer ladle refining of stove and the electric furnace stove mostly in recent years, has received very good effect.Particularly smelt special rolling-mill sections such as high-grade alloy steel, stainless steel, ultra-low-carbon steel, can reach deoxidation, the degassing, decarburization removal non-metallic inclusion, make alloying even through ar blowing refining in the stove.Argon can make product on mechanical property, obviously improve in the stove, and especially plasticity and toughness have solved problems such as splitting gas that steel, casting produce and casting crack, and product quality is obviously improved, and metallographic structure is clearly better.So in electric furnace steel making, list Argon technology in the stove in important process.But electric furnace steel making is long the duration of heat, and every heat was smelted 40-120 minute, the particularly innovation of electric furnace liner material and development, and the life-span in furnace life is brought up to hundreds of stoves.Be difficult to satisfy the life cycle of whole stove labour the service life of the critical component air brick of Argon technology in the stove, and the development of restriction electric furnace smelting special rolling-mill section becomes the focus that expert and insider pay close attention to.Therefore develop reach a kind of service life hundreds of heats can be in stove the induction furnace of blown inert gas, be the present technical issues that need to address.
Summary of the invention
The utility model technical problem to be solved provide a kind of can be in stove the induction furnace of blown inert gas.
The technical scheme that the utility model solves its technical problem is:
A kind of can be in stove the induction furnace of blown inert gas; Comprise body of heater and furnace lining; Be inlaid with 1-5 air brick in the bottom of furnace lining; The height of air brick equals or a little more than the thickness of bottom furnace lining, is provided with the inert gas appendix that equates with air brick quantity in the bottom of body of heater through the hole, is provided with the inert gas appendix in the bottom of air brick; The inert gas appendix is communicated with outward and with the inert gas source of the gas through the furnace bottom that above-mentioned inert gas appendix stretches out body of heater through the hole, and the ventilative wadding of one deck has been made on the top of furnace lining and air brick firm by ramming in the bottom.
The technical scheme that the utility model solves its technical problem can also be:
The utility model is provided with the mica paper bed course between furnace lining and body of heater.
The described air brick of the utility model is made up of spill housing and magnesia, the high alumina matter or the magnalium fire resistant materials that are filled in the spill housing; Described inert gas appendix is connected fixing with the bottom of spill housing and the inert gas appendix is communicated with the inner chamber of spill housing; Top, coat at the refractory material of air brick has one deck paraffin, in the baker process, and melted paraffin wax; Form miniature gas cell, be beneficial to the winding-up of inert gas.
The described air brick of the utility model is diffusion-type, slit-type or compound air brick.
The described paraffin of the utility model is 58# paraffin, and the thickness of paraffin layer is 1-2mm.
The material of the described spill housing of the utility model is pottery or high-melting-point alloy.
The thickness of the described ventilative wadding of the utility model is the 50-250 millimeter.
Compared with prior art, the utlity model has following advantage: air brick is not corroded by molten steel directly, and the long service life of air brick, permeability are stablized, air brick does not stop up, easy to operate, smelting safety, have stopped the bleed-out accident and have taken place.Have the air brick of on induction furnace, installing now and can only use a stove labour, the life-span is only within 100 heats.The utility model is " a kind of gas is blown into the blowing method in the induction furnace ", and its air brick can use 2-3 stove labour, and can reach more than the hundreds of heat service life of air brick.
