Description
Technical field
The utility model relates to the improvement of the furnace water-cooling mouth that uses on the steel-making converter, and specifically furnace water-cooling mouth of a kind of long lifetime is applicable to the converter that 150t is following.
Technical background
Furnace water-cooling mouth is one of vitals of steel-making converter, and its life-span directly has influence on the furnace life and the production of converter.The furnace water-cooling mouth basic form is divided into two kinds at present: a kind of is the cast iron pipe embedded typ, a kind of is that steel plate welds water tank type, divide monoblock type and split type, life-span, generally about the 5000-8000 stove, along with the maturation of spattering slag hearth furnaceman technology, furnace life was more and more longer, average furnace life is more than 20,000 stoves, and the furnace water-cooling mouth life-span is shorter relatively, and not only restriction is produced, and threatens the person, device security.Discover by inquiry cause short reason of water-cooled stove life-span mainly contain following some:
(1) steel plate welding water tank type, the design thickness of its steel plate is improper, too thin insufficient strength, too thick cooling is bad, and the big generation stress of inside and outside temperature difference weld seam is easy to crack.
(2) cast iron pipe embedded typ, cast iron plasticity is poor, and thermal expansivity is little, and inner ring is because of the bad thermal crack that occurs of cooling performance at high temperature for a long time, and the power that is hit and thermal stresses are easily split, and split back pipe laying drawing crack and leak, and can't repair and scrap.
(3) current are not smooth, and it is stifled easily to produce gas (vapour), and water cavity can not be full of, and cools off bad easy scaling loss.
(4) thermal stresses in use is difficult to eliminate.
(5) diameter of furnace water-cooling mouth design is improper, too smallly clashes into when being subject to add steel scrap, and excessive cooling is not enough, the easy accumulated slag of fire door.
Summary of the invention
The purpose of this utility model be to provide a kind of structure design more rationally, good cooling results, current be unimpeded, eliminated the stifled phenomenon of gas (vapour), eliminated thermal stresses during fire door uses, solve weld cracking, its with converter stove labour synchronous or longer long lifetime furnace water-cooling mouth of life-span.
For reaching above purpose, the technical scheme that the utility model adopted is: this long lifetime furnace water-cooling mouth, by base plate, outer panel, cover plate, rising pipe, water inlet pipe constitutes, base plate and cover plate are fixed as an integral body by outer panel, in it is characterized in that between base plate and cover plate, being provided with, the outer shroud water pipe, advance, in rising pipe is located at respectively, the end of outer shroud water pipe, advancing, adopt division plate to leave dilatation joint between the rising pipe, the outer end of division plate is connected and fixed by expansion ring, interior, establish annular bucket type water-stop sheet between the outer shroud water pipe, make water coolant be full of cavity all the time, current are unimpeded; Cover plate is the drum curved cover plate, during expanded by heating, can produce self-adaptation and make a concession, eliminate thermal stresses in the use, and enough intensity is arranged, make fire door not have obvious distortion, the water outlet of interior ring water pipe is communicated with water chamber, and the upper water-out mouth of rising pipe stretches in the water chamber, it is protruding to establish drum on the cover plate at the water outlet place of rising pipe, make water exit the highest, effectively eliminated the stifled phenomenon of gas (vapour), cooling is good.The utility model is also implemented by following measure: described annular bucket type water-stop sheet, constitute by outer ring plate, inner ring plate and transverse slat, transverse slat will be separated into 4-8 bucket-shaped water cavity between outer ring plate and the inner ring plate, the limbers is established at middle part at transverse slat, bucket-shaped water cavity is connected, when water flowed between inside and outside ring flat-plate, water entered from the limbers of transverse slat in the bucket-shaped water cavity between the transverse slat; Described outer shroud water pipe is fixed on the base plate by back up pad, is provided with pin-and-hole on the periphery of base plate; The inwall of interior ring water pipe is the inner ring of fire door, adopts heavy wall boiler weldless steel tube to make, and has optimized furnace port diameter, to reduce the high-temperature zone weld seam, the intensity and the shock-resistance of enhancing fire door; Material of the present utility model is selected the quality steel plate that thermotolerance is good, can adapt to hot environment, reduces hot corrosion of metal and distortion; Principal weld of the present utility model adopts the argon arc welding bottoming, all weld seam continuous weldings, and each parts strictness is welded in order, and to guarantee being provided with residue, iron filings and other foreign material in the cavity, welding stress is eliminated in integrally annealed after finishing.When using the utility model, adopt pin and wedge and converter mouth ring flange to be connected and fixed, fixation, easy accessibility, water inlet pipe adopt the metallic hose connection, and be easy for installation, the stress in the time of can eliminating rigidity and be connected work.
The beneficial effects of the utility model are: compare with the furnace water-cooling mouth of present use, its structure is more reasonable, and current are unimpeded, and it is stifled not produce gas (vapour), good cooling results, and fire door is difficult for accumulated slag, and dry slag easily comes off; Dilatation joint and drum curved cover plate can produce self-adaptation and make a concession thermal stresses during elimination is used during expanded by heating; The inner ring of furnace water-cooling mouth adopts heavy wall boiler weldless steel tube, has reduced the high-temperature zone weld seam; Adopt the high-quality boiler steel, reduce hot corrosion of metal and distortion; Water inlet pipe and water outlet pipe adopts metallic hose to connect during installation, stress that having avoided is rigidly connected causes and installation inconvenience.Above advantage prolongs the work-ing life of furnace water-cooling mouth significantly.
