Abstract
The invention discloses a smelting steel ladle. The smelting steel ladle comprises a steel ladle shell, a steel ladle castable permanent layer combined with the inner side wall of the shell, a working layer combined with the inner side wall of the steel ladle castable permanent layer and a lining brick fixing plate arranged above a steel ladle opening. The lining brick fixing plate is arranged on the position, 100 nm to 200 nm away from the lower edge of the steel ladle opening, of the inner side wall of the steel ladle shell. The lining brick fixing plate is provided with a refractory protection layer. The middle of the working layer on the side wall of the steel ladle shell is provided with erosion prevention steel plates. The middle of a working layer of the bottom in the steel ladle shell is provided with a steel plate impact region. The lining brick fixing plate above the steel ladle opening of the smelting steel ladle is not prone to being damaged, and impact damage to the working layer is lowered effectively through the erosion prevention steel plates and the steel plate impact region in the pouring process of molten steel. The smelting steel ladle has the beneficial effects of being simple in structure, high in strength and long in service life.
Description
Technical field
The present invention relates to steelmaking equipment, particularly relate to a kind of ladle of making steel.
Background technology
Ladle is one of visual plant of steel-making, and the cost of length on manufacturing enterprise in its service life has direct impact.For the ladle of converter, see Fig. 1, comprise ladle housing, be compounded in the pouring materialfor steel ladle permanent layer on above-mentioned case inside wall, and be compounded in the working lining on above-mentioned pouring materialfor steel ladle permanent layer madial wall.Be in the above-mentioned working lining in ladle inner wall not region, according to different requirements, adopt the fire proof material brick of unlike material.Because ladle is in the processes such as converter tapping, Argon stirring, because molten steel or slag meet impact site place at the bottom of steel face position, lower slag lining, top of the slag position and bag to ladle inner wall.
Faster than other position of the erosive velocity of working lining, makes ladle molten bath brick and residue pile can not reach balanced and consumes, have a strong impact on the service life of overall ladle.By analysis, think its immediate cause be the molten bath brick layer height in ladle deslagging face and planform unreasonable caused by.Chinese patent CN201020263485.0 discloses a kind of ladle for converter, comprise ladle housing, be compounded in the pouring materialfor steel ladle permanent layer on above-mentioned case inside wall, and the working lining be compounded on above-mentioned pouring materialfor steel ladle permanent layer madial wall, above-mentioned working lining be meet impact site at the bottom of steel face position, lower slag lining, top of the slag position and bag by ladle inner wall easily corrode working lining everywhere, form with the geologic erosion working lining at other position, the thickness of above-mentioned easy erosion working lining is greater than the thickness of the geologic erosion working lining of respective vicinity respectively everywhere.Thicken the thickness of each easy erosion working lining of ladle, ladle integral has been extended service life greatly, reduces maintenance cost, saved maintenance time, improve production efficiency accordingly.Chinese patent CN201020252427.8 discloses a kind of molten steel ladle, be made up of the nozzle brick of the high alumina casting bed of material in steel ladle, steel ladle, molten bath brick layer, ladle bottom, by in the molten bath brick layer in the deslagging face after ladle molten bath brick layer decline 200 ~ 600 millimeters, build the trapezoidal molten bath anticorrosion layer equal with falling head by laying bricks or stones; 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 in ladle and shape rational modification, improve the life cycle of ladle, be namely increased to 130 times 100 times by original use, reduces costs significantly, also improve unit operation rate simultaneously.But the damage of lining brick fixed head affects the service life of ladle equally above ladle mouth.
Summary of the invention
The technical problem that one, will solve
The object of the invention is for the problems referred to above existing for prior art, spy provides a kind of and smelts ladle, above effectively solving the smelting ladle service life of prior art, ladle mouth, lining brick fixed head is fragile, in molten steel toppling process, and the defect of working lining easy damaged on ladle inner wall.
Two, technical scheme
For solving the problems of the technologies described above, the invention provides a kind of smelting ladle, comprise ladle housing, be compounded in the pouring materialfor steel ladle permanent layer on above-mentioned case inside wall, be compounded in the working lining on above-mentioned pouring materialfor steel ladle permanent layer madial wall, and the lining brick fixed head above ladle mouth, above-mentioned lining brick fixed head is arranged under ladle mouth along on the madial wall of the ladle housing at 100-200mm place, above-mentioned lining brick fixed head is provided with the protective layer of resistance to material, protection against erosion steel plate is provided with in the middle part of working lining in above-mentioned ladle housing sidewall, impact zone is provided with in the middle part of the working lining of above-mentioned ladle housing inner bottom part.
As optimization, between above-mentioned top lining brick fixed head and ladle housing, be provided with reinforcement.
As optimization, above-mentioned top lining brick fixed head is arranged under ladle mouth along on the madial wall of the ladle housing at 150mm place.
As optimization, between above-mentioned top lining brick fixed head and ladle housing, uniform welding has multiple reinforcement.
As optimization, above-mentioned impact zone is set to steel plate structure.
The present invention compared with prior art; lining brick fixed head above ladle mouth; it is the ladle brick of fixing ladle; when LF stove and VD stove are smelted; because of the high-temperature oxydation of slag; lining brick fixed head well damage above this; lining brick fixed head entirety above ladle mouth moves down along ladle mouth by the present invention; lining brick fixed head is spread the protection of resistance to material above this; and even reinforcement of burn-oning, improve the service life of top lining brick fixed head, reduce maintenance cost; alleviate the labour intensity of workman, also improve the service life of ladle simultaneously.
Three, beneficial effect of the present invention
Above the ladle mouth of smelting ladle of the present invention, lining brick fixed head is not fragile, and protection against erosion steel plate and steel plate impact zone effectively reduce molten steel impact injury to working lining in toppling process, has that structure is simple, intensity is high, the advantage of long service life.
