Abstract
The utility model discloses an efficient thermal insulation structure of a steel ladle for a refining furnace, and belongs to metallurgy steelmaking equipment. The efficient thermal insulation structure is encircled by a steel shell, a permanent layer and a working layer sequentially from outside to inside, wherein the permanent layer is formed by a thermal insulation plate layer, a spinel layer and a carbonaceous brick layer sequentially from outside to inside; and green mud is filled in an annular space between a wall construction layer of the steel ladle for the refining furnace and a ladle bottom construction layer. According to the efficient thermal insulation structure of the steel ladle for the refining furnace, materials of the permanent layer formed in the mode are high in heat conduction resistance and molten steel penetration resistance, so that a shell of the steel ladle can be maintained at a lower temperature, the service life of the permanent layer of the steel ladle is prolonged, and the safety performance of the permanent layer is improved. Due to the adoption of the permanent layer, an overheating aflame phenomenon of the shell of the steel ladle can be prevented, and the phenomenon of steel leakage is prevented; and the permanent layer of the steel ladle can be continuously used for multiple years, and the efficient thermal insulation structure has an extremely good effect, popularization value and using value.
Description
Technical field
The utility model belongs to metallurgical steelmaking equipment, particularly relates to the high-efficiency insulated structure of a kind of refining furnace ladle.
Background technology
Normally two-layer masonry way on the permanent layer of present metallurgical ladle, ground floor are that thickness is the asbestos board of 10mm, and the second layer is that thickness is the clay matter insulating brick of 65mm.Because heat insulation and heat preservation effect are poor, often cause the rubescent phenomenon of shell of ladle to take place with bleed-out, and often can not be synchronous with the life-span of the magnesia carbon brick of working lining, influenced the life-span of ladle working layer greatly.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, provides a kind of refining furnace ladle high-efficiency insulated structure, and two-layer the building by laying bricks or stones of existing permanent ladle layer changed into three layers and build by laying bricks or stones, and material has also been carried out great improvement.Solved the heat insulation and bad problem of heat insulation effect of permanent ladle layer; Improved the service life of permanent ladle layer simultaneously, made the life-span of the life-span of permanent layer considerably beyond working lining.Good heat-insulating property that permanent ladle layer has and powerful anti-molten steel penetration performance have reached the purpose that guarantees working lining magnesia carbon brick ultimate life.
The high-efficiency insulated structure of refining furnace ladle of the utility model, ring is wrapping box hat, permanent layer and working lining formation successively from outside to inside, and permanent layer is thermal baffle layer, spinel layer and carbon brick layer from outside to inside successively.
Do novel further improvement as this reality, described working lining is to be built by laying bricks or stones by magnesia carbon brick to constitute.
Do novel further improvement as this reality, refining furnace steel ladle wall is built layer by laying bricks or stones and is wrapped the annular space filling green mud of building layer by laying bricks or stones in the end.
The high-efficiency insulated structure of refining furnace ladle of the utility model; This permanent layer material that combines has excellent heat resistanceheat resistant conductibility and powerful anti-molten steel penetration property; Can guarantee that the ladle shell maintains lower temperature, thereby improve the service life and the security performance of permanent ladle layer.Use permanent layer of the present invention, overheated rubescent phenomenon can not appear in the ladle shell, and has stopped the generation of bleed-out phenomenon, and permanent ladle layer can use the several years continuously, and effect is very good, has promotion and use value.
Description of drawings
Fig. 1 is the section of structure of the high-efficiency insulated structure of refining furnace ladle.
The specific embodiment
The high-efficiency insulated structure of refining furnace ladle of the utility model, ring is wrapping box hat 1, permanent layer and working lining 6 formations successively from outside to inside, and described permanent layer is thermal baffle layer 4, spinel layer 3 and carbon brick layer 2 from outside to inside successively.Thermal insulation board 4 is nanoscale speciality thermal insulation thermal insulation boards, and thickness is 5-15mm, and it is original more than 300% that effect of heat insulation can reach; Spinel layer 3 is a spinel pouring material, and thickness is 25-50mm, and spinel pouring material has good chemical resistance of concrete property, also is a kind of refractory material; Carbon brick layer 2 is to build layer by laying bricks or stones by the magnesia carbon brick that fused magnesite and crystalline flake graphite are processed, and thickness is 80-130mm.Build by laying bricks or stones for three layers, strengthened heat insulation, insulation and erosion-resisting effect greatly.
Working lining 6 is to be built by laying bricks or stones by magnesia carbon brick to constitute.Magnesia carbon brick has good resistance to slag corrosion, slag penetration property, thermal shock resistance and thermal conductivity, is the good material of refining furnace liner.Refining furnace steel ladle wall is built layer by laying bricks or stones and is wrapped the annular space filling green mud 5 of building layer by laying bricks or stones in the end.Green mud 5 has absorption, bonding, fastening effect, guarantees the durable in use of ladle.
Claims (3)
1. the high-efficiency insulated structure of refining furnace ladle is encircled successively from outside to inside and is being wrapped box hat (1), permanent layer and working lining (6) formation, it is characterized in that permanent layer is thermal baffle layer (4), spinel layer (3) and carbon brick layer (2) from outside to inside successively.
2. the high-efficiency insulated structure of refining furnace ladle according to claim 1 is characterized in that working lining (6) is to be built by laying bricks or stones by magnesia carbon brick to constitute.
