Description
Technical Field
The utility model relates to a ladle, concretely relates to accident ladle.
Background
The accident ladle is a spare ladle furnace used in an accident state, does not participate in molten steel containing operation under the normal production condition, and has different masonry process and requirements from normal production ladles. The accident steel ladle used before is constructed by universal arc bricks in single layer, and the wall and bottom of the ladle are directly constructed by clay bricks and yellow sand. With the change of ecological environment of metallurgical industry, the accident ladle can not meet the requirements of the current industry.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects of the prior art, the utility model provides an accident ladle.
The technical scheme is as follows: the utility model relates to an accident steel ladle, which comprises a cladding with an axis longitudinal section in a U shape, a ladle wall lining built on the inner side of the side wall of the cladding, and a ladle bottom lining built on the upper part of the shell bottom of the cladding; the ladle wall lining comprises a high-alumina brick layer, a magnesium joint filling layer and a magnesia carbon brick layer which are sequentially arranged from the side wall of the ladle shell to the inside, and the ladle wall lining extends from the upper surface of the ladle bottom lining to the upper edge of the ladle shell; the ladle bottom lining comprises a corundum pouring material leveling layer and an alumina-magnesia carbon brick layer which are sequentially arranged from the shell bottom of the ladle shell to the upper part, and a gap between the ladle bottom lining and the side wall of the ladle shell is tightly plugged by magnesia carbon bricks and is tamped by magnesia pouring materials.
Has the advantages that: compared with the prior art, the accident ladle adopts multilayer masonry, and has good molten steel scouring resistance and corrosion resistance; the lining structure is reinforced, and the capacity of the ladle is not influenced; the ladle is simple in structure, and ladle turning processing of accident ladles is facilitated.
Drawings

fig. 2 is the structural schematic diagram of the accident ladle bottom of the utility model.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the embodiment discloses an accident ladle, which comprises a ladle shell 1 with an axial longitudinal section in a U shape, a ladle wall lining built on the inner side of the side wall of the ladle shell 1, and a ladle bottom lining built above the shell bottom of the ladle shell 1.
Specifically, the ladle wall lining comprises a high-alumina brick layer 2, a magnesium joint filling layer 3 and a magnesium carbon brick layer 4 which are sequentially arranged from the side wall of the ladle shell inwards, and the ladle wall lining extends to the upper edge of the ladle shell 1 from the upper surface of the ladle bottom lining. Wherein, in order to ensure the strength of the wall-wrapping structure to be more firm, the thickness of the high-alumina brick layer 2 is preferably 1/2 which is the same as that of the magnesia carbon brick layer 4. Further, the thickness of the magnesia carbon brick layer 4 is not less than 60mm, and the thickness of the magnesia joint filling layer 3 is not less than 10 mm.
The ladle bottom lining comprises a corundum pouring material leveling layer 5 and an alumina-magnesia carbon brick layer 6 which are sequentially arranged from the shell bottom of the ladle shell to the upper part, and a gap between the ladle bottom lining and the side wall of the ladle shell 1 is tightly plugged by magnesia carbon bricks and is tamped by magnesia pouring materials. Correspondingly, the thickness of the alumina-magnesia carbon brick layer 6 is not less than 100mm, so as to ensure the erosion resistance.
The construction requirements of the accident ladle are as follows:
building a ladle bottom: and leveling the shell bottom of the cladding 1 by using an aluminum-magnesium casting material, building by using 100mm aluminum-magnesium carbon bottom-wrapping bricks after leveling, plugging a gap between the bottom-wrapping bricks and the cladding wall by using magnesia carbon bricks, and tamping a small gap by using the magnesia casting material.
Building a ladle wall: the method comprises the following steps of (1) building by adopting a double-layer process, wherein the first layer is built by a high-aluminum brick vertical building process with the thickness of 30mm, and is tightened by wedge-shaped bricks; the second layer is built by a magnesia carbon brick flat building process with the thickness of 60mm, and after each layer of magnesia carbon bricks is closed, the brick joints are tightened by a crowbar; the second layer is staggered with the first layer of brick joints; a gap of 10mm is left between the two layers and is filled and tamped by a magnesium joint filler. And leveling gaps between the ladle wall working layer bricks and the ladle bottom by using corundum castable. The ladle bottom is used as a base to be built along the ladle wall to the ladle edge.
