Abstract
The utility model discloses a smelting steel ladle, which comprises a steel ladle shell, a steel ladle pouring material permanent layer, a working layer and an upper lining brick fixing plate. The steel ladle pouring material permanent layer is compounded on the inner sidewall of the steel ladle shell, the working layer is compounded on the inner sidewall of the steel ladle pouring material permanent layer, and the upper lining brick fixing plate is arranged at an opening of the steel ladle and on the inner sidewall of the steel ladle shell at 100-200mm of the lower edge of the opening of the steel ladle and is provided with a wear material protection layer. The upper lining brick fixing plate at the opening of the smelting steel ladle cannot be damaged easily, and the smelting steel ladle has the advantages of simple structure, high strength and long service life.
Description
Technical field
The utility model relates to steelmaking equipment, relates in particular to a kind of ladle of making steel usefulness.
Background technology
Ladle is one of visual plant of steel-making, and the length in its service life has direct influence to the cost of manufacturing enterprise.The ladle that is used for converter referring to Fig. 1, comprises the ladle housing, is compounded in the pouring materialfor steel ladle permanent layer on the said housing madial wall, and is compounded in the working lining on the said pouring materialfor steel ladle permanent layer madial wall.Be in the not regional said working lining of ladle inner wall,, adopt the fire proof material brick of unlike material according to different requirement.Because ladle is in processes such as converter tapping, Argon stirring; Invar water or slag are met the facial position of steel, the erosive velocity of impact site place working lining faster than other position at the bottom of slag lining, top of the slag position and the bag down to ladle inner wall; Make ladle molten bath brick and slag line brick can not reach balanced and consume, have a strong impact on the service life of whole ladle.Through analyzing, think its immediate cause be molten bath brick layer height and the planform of ladle deslagging face unreasonable due to.Chinese patent CN201020263485.0 discloses a kind of ladle that is used for converter; Comprise the ladle housing; Be compounded in the pouring materialfor steel ladle permanent layer on the said housing madial wall; And be compounded in the working lining on the said pouring materialfor steel ladle permanent layer madial wall; Said working lining is to meet the facial position of steel, the normal erosion working lining formation that is prone to corrode working lining and other position everywhere of impact site at the bottom of slag lining, top of the slag position and the bag down by ladle inner wall, and the thickness of said everywhere easy erosion working lining is respectively greater than the thickness of the normal erosion working lining of vicinity separately.Each is prone to corrode the thickness of working lining to have thickeied ladle, makes ladle integral prolong greatly service life, has reduced maintenance cost, has practiced thrift maintenance time, has improved production efficiency accordingly.Chinese patent CN201020252427.8 discloses a kind of molten steel ladle; Nozzle brick by the high alumina casting bed of material in ladle wall, the ladle wall, molten bath brick layer, ladle bottom is formed; Ladle molten bath brick layer is descended on the molten bath brick layer of the deslagging face after 200～600 millimeters, build the trapezoidal molten bath anticorrosion layer that equates with falling head by laying bricks or stones; The molten bath anticorrosion layer protrudes molten bath brick layer and forms step, and the protrusion length of its step is 20～60 millimeters.Molten bath brick layer structure and shape in the ladle are rationally improved, and improve the life cycle of ladle, promptly are increased to for 100 times 130 times by original use, reduce cost significantly, have also improved the unit operation rate simultaneously.But the damage of ladle mouth top lining brick fixed head influences the service life of ladle equally.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of service life, non-damageable smelting ladle of ladle mouth top lining brick fixed head that can improve ladle is provided.
The utility model is realized through following technical scheme:
Smelt ladle; Comprise the ladle housing, be compounded in pouring materialfor steel ladle permanent layer on the said housing madial wall, be compounded in working lining and ladle mouth top lining brick fixed head on the said pouring materialfor steel ladle permanent layer madial wall; Described top lining brick fixed head is arranged on the madial wall of ladle housing at 100-200mm place, ladle mouth lower edge, and described top lining brick fixed head is provided with the protective layer of anti-the material.
Be provided with reinforcement between described top lining brick fixed head and the ladle housing.
Described top lining brick fixed head is arranged on the madial wall of ladle housing at 150mm place, ladle mouth lower edge.
Evenly be welded with reinforcement between described top lining brick fixed head and the ladle housing.
The utility model compared with prior art, ladle mouth top lining brick fixed head is the fixing ladle brick of ladle; When LF stove and the smelting of VD stove, the high-temperature oxydation of invar slag, this top lining brick fixed head well damage; The utility model moves down ladle mouth top lining brick fixed head integral body along the ladle mouth, above this, spread anti-material protection on the lining brick fixed head, and the even reinforcement of burn-oning; Improved the service life of top lining brick fixed head; Reduced maintenance cost, alleviated working strength of workers, the service life of also having improved ladle simultaneously.
Description of drawings
Fig. 1 is a structural representation of smelting ladle in the prior art,
Fig. 2 is the structural representation of the utility model embodiment,
Fig. 3 is the vertical view of Fig. 2.
Sequence number among the figure: 1, ladle housing, 2, the pouring materialfor steel ladle permanent layer, 3, working lining, 4, top lining brick fixed head, 5, reinforcement, 6, the protective layer of anti-the material.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
According to Fig. 2 and shown in Figure 3; A kind of smelting ladle of the utility model; Comprise ladle housing 1, be compounded in pouring materialfor steel ladle permanent layer 2 on said housing 1 madial wall, be compounded in working lining 3 and ladle mouth top lining brick fixed head 4 on said pouring materialfor steel ladle permanent layer 2 madial walls; Described top lining brick fixed head 4 is arranged on the madial wall of ladle housing 1 at 150mm place, ladle mouth lower edge; Evenly be welded with reinforcement 5 between described top lining brick fixed head 4 and the ladle housing 1, described top lining brick fixed head 4 is provided with the protective layer of anti-material the 6.
Embodiment is just for the ease of understanding the technical scheme of the utility model; Do not constitute restriction to the utility model protection domain; Every interior any simple modification, equivalent variations and modification of perhaps according to the technical spirit of the utility model above scheme being done that does not break away from the utility model technical scheme all still belongs within the utility model protection domain.
