Abstract

The invention discloses an anti-steel-seepage furnace floor structure. The anti-steel-seepage furnace floor structure is composed of a furnace floor area, a furnace floor arc transition area and a molten pool transition area; the furnace floor area, the furnace floor arc transition area and the molten pool transition area are each provided with a lower permanent layer furnace lining and an upper working layer furnace lining, and the working layer furnace lining of the furnace floor arc transition area is closely built on the permanent layer furnace lining of the furnace floor arc transition area; the working layer furnace lining of the molten pool transition area is closely built on the permanent layer furnace lining of the molten pool transition area; and a triangle area is generated among the permanent layer furnace lining of the furnace floor arc transition area, the working layer furnace lining of the furnace floor arc transition area, the permanent layer furnace lining of the molten pool transition area and the working layer furnace lining of the molten pool transition area. The anti-steel-seepage furnace floor structure can give full play to the advantages of high density andhigh strength of shaping products.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment, in particular to a furnace bottom structure of anti-seepage steel. Background technique [0002] There are two main types of converter bottoms: flattened bottom and progressive flattened bottom. At present, progressive flattened bottom is widely used at home and abroad. This kind of masonry has good integrity and can effectively decompose heat in the furnace bottom and molten pool area. Stress, prolong the service life of the converter and other advantages. The defect of this structure is that there will be a large number of triangular areas in the permanent layer and the working layer in the arc transition area of ​​the furnace bottom and the molten pool arc transition area, and the triangular area is filled with magnesia or magnesia-chrome fillers Form the packing area. Due to the poor strength of the filling material, the filling material is easy to loosen and break under the c...
