Above-mentioned ladle, includes separate skin and internal layer from ladle bottom to the working lining in slag line district, and working lining thickness is D, and outer layer thickness is N, and internal layer thickness is M, N=10%D-40%D, M=D-N.
Above-mentioned ladle, outer and internal layer is all formed by working lining brick building by laying bricks or stones in layer from bottom to top, and outer field working lining brick brick layer thickness H equates with the working lining brick brick layer thickness H of internal layer.
Above-mentioned ladle, outer layer thickness N=50mm, the internal layer thickness M=130mm in molten bath district, the internal layer thickness M=150-170mm in slag line district.
Above-mentioned ladle, the internal layer thickness M=170mm of bottom, slag line district, the internal layer thickness M=150mm on top, slag line district.
Above-mentioned ladle, outer and internal layer is all formed by working lining brick building by laying bricks or stones in layer from bottom to top, and the working lining brick brick layered suture in working lining brick brick layered suture and internal layer in skin is staggered up and down.
Above-mentioned ladle, outer field working lining brick brick layer thickness H equates with the working lining brick brick layer thickness H of internal layer; Outer working lining brick brick layered suture and the neighbouring internal layer working lining brick brick layered suture difference in height between the two equals the half of working lining brick brick layer thickness H.
Above-mentioned ladle, outer field working lining brick is arc magnesia carbon brick, the working lining brick of internal layer is combination or the arc magnesia carbon brick of double-wedge magnesia carbon brick, straight type magnesia carbon brick and wedge shape magnesia carbon brick; Permanent layer is formed by high-alumina brick building by laying bricks or stones in layer from bottom to top, and permanent layer also can be that high alumina castable is integrated poured to be formed.
The beneficial effects of the utility model are:
(1) permanent layer is built by laying bricks or stones with high-alumina brick, and working lining is built by laying bricks or stones with magnesia carbon brick, and the heat-insulating property of high-alumina brick is better than magnesia carbon brick, and the erosion-resisting characteristics of magnesia carbon brick is better than high-alumina brick greatly, but the price of the cost ratio magnesia carbon brick of high-alumina brick is low; The permanent layer of comparing and working lining all use the ladle of magnesia carbon brick: utilized on the one hand the heat-insulating property of high-alumina brick, made the liquid steel temperature can fast cooling, avoided skin temperature too high even rubescent, saved the energy; Also the erosion-resisting characteristics of having utilized on the other hand magnesia carbon brick, has also reduced ladle cost.
(2) working lining is divided into separate skin and internal layer, after the working lining brick erosion of internal layer has been damaged, in carrying out, repair or when the whole working lining of light maintenance, replacing slag line district's working lining or bag wall, only need to change the working lining brick of internal layer, outer field working lining brick is repeatedly reusable, can reduce like this waste causing because changing steel ladle working lining brick, reduce refractory consumption rate, and then reduction steel-making cost, guarantee safe handling simultaneously, and sentence containing easily.

Detailed description of the invention
As shown in Figure 1, the steel ladle of ladle comprises shell, heat-insulation layer, permanent layer and working lining from outside to inside successively, the working lining in slag line district comprises outer and internal layer (working lining in molten bath district is only one deck), outer between internal layer and permanent layer, the working lining thickness in slag line district is D, and outer layer thickness is N, and internal layer thickness is M, N=10%D-40%D, M=D-N; Preferably N=20%D-30%D, N is relative, and D is less, and after the working lining brick of internal layer corrodes, the erosion time of outer field working lining brick opposing ladle slag is shorter; N is relative, and D is larger, and after the working lining brick of internal layer corrodes, the erosion time of outer field working lining brick opposing ladle slag is longer.N=20%D-30%D, after ensureing on the one hand the working lining brick erosion of internal layer, outer field working lining brick has the erosion duration of suitable opposing ladle slag, guarantees the use safety of ladle; Also the working lining brick that can guarantee on the other hand internal layer has enough thickness, extend in carrying out repair, light maintenance and change slag line district working lining or the time interval of the whole working lining of bag wall.
Shown in Fig. 2, the steel ladle of ladle comprises shell, heat-insulation layer, permanent layer and working lining from outside to inside successively, include skin and internal layer from ladle bottom to the working lining in slag line district, outer between internal layer and permanent layer, the working lining thickness in slag line district is D, and outer layer thickness is N, and internal layer thickness is M, N=50-80mm, M=D-N.The present embodiment ectomesoderm thickness is N=50mm, the internal layer thickness M=130mm in molten bath district, the internal layer thickness M=170mm of bottom, slag line district, the internal layer thickness M=150mm on top, slag line district.When use, only change internal layer thickness for 130mm, 150mm or 170mm part, and protection outer layer thickness is 50mm part, has so just reduced cost, has still ensured the use safety of ladle simultaneously.
In Fig. 1 and Fig. 2, outer and internal layer is all formed by working lining brick building by laying bricks or stones in layer from bottom to top; In Fig. 2 internal layer from ladle bottom to slag line district totally 28 floor working lining brick; In Fig. 1, just the working lining in slag line district is divided into skin and internal layer, and the internal layer in Fig. 1 is totally 12 layers of working lining brick; Outer field working lining brick is arc magnesia carbon brick, and the working lining brick of internal layer is combination or the arc magnesia carbon brick of double-wedge magnesia carbon brick, straight type magnesia carbon brick and wedge shape magnesia carbon brick; Permanent layer is formed by high-alumina brick building by laying bricks or stones in layer from bottom to top, and permanent layer also can be that high alumina castable is integrated poured to be formed; The main brick type design chord length L of radial brick is 250mm or other sizes, and radial brick radius R depends on ladle wall centre position permanent layer inwall radius.Working lining brick brick layered suture in working lining brick brick layered suture and internal layer in skin is staggered up and down, and outer field working lining brick brick layer thickness H equates with the working lining brick brick layer thickness H of internal layer; Outer working lining brick brick layered suture and the neighbouring internal layer working lining brick brick layered suture difference in height between the two equals the half of working lining brick brick layer thickness H.
Permanent layer in the utility model is still used low-grade material (material that price is lower, as high-alumina brick) with respect to working lining, and the skin of working lining and internal layer all adopt high-grade material (material that price is higher, as magnesia carbon brick).After the working lining brick erosion of internal layer has been damaged, in carrying out, repair or light maintenance, while changing the whole working lining of slag line district working lining or bag wall, only need to change the working lining brick of internal layer, outer field working lining brick is repeatedly reusable; Compare original one deck working lining, reduced the using and wasting of working lining brick of internal layer, single bag refractory consumption rate reduces a lot, can be every year steel mill cost-saving millions of.Even if it is complete that the working lining brick of internal layer corrodes, outer field working lining brick also can be resisted the erosion of ladle slag, ensures the use safety of ladle.
