Background technique
In non-ferrous metal metallurgy industry, especially Copper making industry, rotary anode refining furnace is most important refining skill
One of art.Anode refining process mainly carries out removing impurities by oxidation, reduction deoxygenation to blowing blister copper and then obtains purity 99.3wt/%
Above anode copper.Anode refining process includes charging, aoxidizes and skim, restore, casting four duty cycles, wherein oxidation is skimmed
It is that operation is carried out by furnace body side air port with reduction process, the heat of oxidation is passed through compressed air, and reduction period is passed through natural gas, again
The reducing agents such as oil or coal dust.Air port is equipped with through-hole, by through-hole can to the molten bath of smelting furnace for oxidizing compressed air or
The reaction mediums such as natural gas, heavy oil, the coal dust of person's reduction.
Air port is placed in molten bath or more in anode refining furnace not operation, when redox operation the furnace body that fascinates be placed in air port
In molten bath, therefore air port area working face temperature fluctuation is the most violent, and the liner corrosion in air port region is the most serious, in addition, blister copper contains
Lead is excessively high also to need to be added quantitative quartz sand slag making, quartz sand exacerbate this field liner brick wash away and chemical attack, 6 months
Left and right brick body integrally cuts down 2/3, dangerous to avoid air port region from leaking copper, needs blowing out cold repair digging, cause system shutdown 12~
15 days, seriously constrain production steady and continuous operation.
The air port of design installation generallys use brick cup, set brick, brick core combined type in industry at present, this design advantage is can be
Cover brick, brick core scaling loss when carry out hot repair replacement, but during the work time there are the following problems:
The first, this design air port brick cup is unable to hot repair replacement, air port brick cup scaling loss or when washing away too short to set brick, brick core
Well damage seriously affects the service life of set brick, brick core.Every production some months needs cold repair digging primary in practical application, cold
Repair the time 12~15 days, the serious driving rate and treating capacity for limiting smelting furnace.
The second, brick cup, set brick, brick core are expensive in this design tuyere device, and standby brick amount is big, serious occupied fund, no
Conducive to organization of production and reduce production cost.
Therefore, when using anode refining nozzle, how to provide that a kind of design is simple, cheap, can have for nozzle
The tuyere device of hot repair replacement, has been that current those skilled in the art need the problem of researching and solving.
Utility model content
The purpose of this utility model is to provide a kind of gland-type smelting furnace, the air port of the utility model smelting furnace can have
The outer hot repair of furnace.

Layer is brick flat arch, and middle layer is lintel brick, and lower layer is brick cup modular tile, and the lower modular tile is divided into three layers from bottom to up, and lower layer is
Brick flat arch, middle layer are lintel brick, and upper layer is brick cup modular tile.
Further, the brick flat arch is made of four blocks of magnesium chromium firebricks arranged side by side, and lintel brick is a laterally setting
Magnesium chromium firebrick, brick cup modular tile is made of three blocks of magnesium chromium fire resisting brick cups arranged side by side, the upper layer brick cup modular tile and
Through-hole is equipped on a block brick among lower layer's brick cup modular tile, the through-hole on two block bricks is connected to form the spray
Rifle channel, length, the equal length of the length of brick flat arch and brick cup modular tile of the lintel brick.
All bricks in the upper modular tile and lower modular tile are in big structure on the outside of the port of furnace inside.
Amorphous refractory coating, the amorphous refractory coating are equipped between the tuyere brick and arc gland
By MgO≤88% in the produced amorphous refractory CP13(amorphous refractory of magnesium difficult to understand (Dalian) Co., Ltd, volume density
≧2.68g/cm3, apparent porosity < 23%, Kang pressure Du≤30N/mm2) coat.
In the utility model, 16 blocks of refractory brick in air port are common refractory brick, and cost significantly reduces.
When furnace door brick, which needs to dismantle, to be built again, the setting of lintel brick peace arch brick effectively prevents it and encloses brick falling off.
The spray gun channel is arranged obliquely from top to bottom, rather than radial direction tilts.Under normal conditions, spray gun channel
Purpose be to place spray gun, in the case where muzzle is embedded to molten bath finite depth, so that high pressure gas circles round in molten bath, increase
The haptoreaction time of gas and molten bath, and then reaction rate is improved, avoid the case where high pressure gas directly punctures molten bath.
The utility model can cut out phase on corresponding furnace shell before creating into furnace brick again according to vent area size
With the shell of size.Production is compact with furnace shell integral sealing with furnace shell radian and the identical arc gland panel of material, has and tears open
It unloads, rigid condition.
It is inner small and outside big (port outside is big on the inside of furnace) that furnace brick used is built in the air port, and the inner small and outside big furnace brick is just
In dismantling masonry outside furnace, it is difficult to solve the problems, such as that the furnace brick masonry of inside and outside same size closes up.
In addition to crossing furnace outside hot repair, it should be noted that first installation fixes gland, uniformly spreads on gland when stove is integrally laid bricks
It lays bricks after amorphous refractory, is bonded with reaching gland with furnace brick perfection again.
The utility model has the beneficial effects that can effectively solve wind using gland-type smelting furnace described in the utility model
Mouthful brick cup scaling loss or when washing away too short to set brick, brick core well damage, set brick, brick core service life is relatively low and brick cup, set
The production problems such as the expensive and standby brick amount of brick, brick core is big.Production practices show novel gland formula smelting furnace, need in furnace body
When repairing, can the digging outside hot repair furnace when molten bath is a small amount of, avoid cold repair blowing out, effectively reduce cold repair number and time, substantially
Driving rate is improved, furthermore common magnesia chrome brick is cheap, reduces resistance to material unit consumption, improves the performance of enterprises.
