Abstract
The utility model discloses a ladle for a steel furnace, which comprises a ladle shell, a ladle pouring material permanent layer which is compounded on the internal side wall of the shell, and working layers which is compounded on the internal side wall of the ladle pouring material permanent layer, wherein the working layers comprise four high-erodibility working layers which are respectively arranged at the steel approaching face part, the roughing slag line part, the slag top part and the ladle bottom impact part of the inner wall of the ladle, and normal-erodibility working layers at other parts. The ladle is characterized in that the thickness of the four high-erodibility working layers is respectively larger than the thickness of respective normal-erodibility working layers close to the four erodible working layers. When the thickness of the normal-erodibility working layers is A1, the reserved safety thickness is B1, the erosion rate is V2, the service life is N1 and the erosion rate of adjacent high-erodibility working layers is V1, the thickness of the high-erodibility working layers is (A1-B1) x V1/V2+B1. The utility model has the advantages that the service life of the ladle can be prolonged, the maintenance cost can be reduced, the maintenance time can be saved and the production efficiency can be improved.
Description
Technical field
The utility model relates to the ladle that is used for steel melting furnace.
Background technology
The ladle that is used for steel melting furnace comprises the ladle housing, is compounded in the Refractory Carstables for Ladles permanent layer on the described housing inner side-wall, and is compounded in the working lining on the described Refractory Carstables for Ladles permanent layer inner side-wall.Be in the described working lining of ladle inner wall different zones,, adopt the fire proof material brick of unlike material according to different requirements.As shown in Figure 2, because ladle is in processes such as converter tapping, Argon stirring, invar water or slag are met the facial position 41 of steel, faster than other position of the erosive velocity of slag lining 42, top of the slag position 43 and bag end impact site 44 place's working linings down to ladle inner wall, make ladle integral shorten work-ing life.
The utility model content
The purpose of this utility model is: provide a kind of ladle that is used for steel melting furnace, the work-ing life that can improve ladle.
For achieving the above object, the utility model can be taked following technical proposals:
The utility model is used for the ladle of steel melting furnace, comprise the ladle housing, be compounded in the Refractory Carstables for Ladles permanent layer on the described housing inner side-wall, and be compounded in working lining on the described Refractory Carstables for Ladles permanent layer inner side-wall, described working lining be by ladle inner wall meet the facial position of steel, down at the bottom of slag lining, top of the slag position and the bag impact site easily corrode working lining everywhere, constitute with the normal erosion working lining at other position, it is characterized in that: the thickness of described everywhere easy erosion working lining is respectively greater than the thickness of the normal erosion working lining of vicinity separately.
The thickness of each described easy erosion working lining is near the normal erosion working lining thickness it 1.05-1.15 times.
The safe thickness that is A1, reservation when described normal erosion working lining thickness is that B1, erosion rate are that V2, work-ing life are N1, and when adjacent easy erosion working lining erosion rate was V1, this thickness that easily corrodes working lining was (A1-B1) * V1 ÷ V2+B1.
The technical solution of the utility model, each easily corrodes the thickness of working lining owing to thickeied ladle, makes ladle integral prolong greatly work-ing life, has reduced maintenance cost, has saved servicing time, has improved production efficiency accordingly.
Generally speaking, the thickness of getting each described easy erosion working lining near the 1.05-1.15 of the normal erosion working lining thickness it doubly.The safe thickness that is A1, reservation when described normal erosion working lining thickness is B1, when erosion rate is V2, N1=in work-ing life (A1-B1) ÷ V2, if the thickness that easily corroding the working lining erosion rate is V1, intend increasing to is C1, be N2=(C1-B1) ÷ V1 the work-ing life of then easily corroding working lining; Best point in work-ing life is N1=N2, and the thickness that just can draw easy erosion working lining in view of the above is: C1=(A1-B1) * V1 ÷ V2+B1.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the ladle of steel melting furnace.
Fig. 2 is the existing structural representation that is used for the ladle of steel melting furnace.
Embodiment
As shown in Figure 1, the utility model is used for the ladle of steel melting furnace, comprise ladle housing 1, be compounded in the Refractory Carstables for Ladles permanent layer 2 on described housing 1 inner side-wall, and be compounded in working lining on described Refractory Carstables for Ladles permanent layer 2 inner side-walls, described working lining be by ladle inner wall meet the facial position 31 of steel, slag lining 32, top of the slag position 33 and bag end impact site 34 easily corrodes working lining everywhere down, constitute with the normal erosion working lining at other position, the thickness of described everywhere easy erosion working lining is respectively greater than the thickness of the normal erosion working lining of vicinity separately.The thickness of preferred each described easy erosion working lining is near the normal erosion working lining thickness it 1.05-1.15 times.Optimal scheme is: the safe thickness that is A1, reservation when described normal erosion working lining thickness is that B1, erosion rate are that V2, work-ing life are N1, when adjacent easy erosion working lining erosion rate was V1, this thickness that easily corrodes working lining was (A1-B1) * V1 ÷ V2+B1.For example, when the normal thickness that corrodes working lining was 250 millimeters at the bottom of the ladle bag, the thickness of the easy erosion working lining at impact site 34 places was 280 millimeters at the bottom of the ladle bag; Meet near the facial position 31 of steel normal erosion working lining thickness when being 200 millimeters, the thickness of meeting the easy erosion working lining of the facial position 31 of steel is 220 millimeters.For reducing the dimensions that working lining is laid bricks, the thickening thickness that easily corrodes working lining is got 10 integral multiple usually.
