Description
Technical field
The utility model belongs to iron-smelting blast furnace technical field, particularly relates to a kind of blast-furnace tuyere mat structure.
Background technology
Blast furnace hearth is the region of preserving molten iron, and this part of heat flow rate per unit area is very high, and because molten iron is to the washing away of cupola well furnace bottom, oxidation and chemical erosion, cupola well furnace bottom is burnt and the phenomenon that causes blast furnace stopping to stop production is of common occurrence at home and abroad.With regard to Modern Large Blast Furnaces body, how to extend the life cycle of cupola well furnace bottom, become a key research topic of blast furnace longevity.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly; and provide a kind of simple in structure; can meet the thermal zone high insulation of blast furnace, low heat conduction, resistance to erosion, the corrosion-resistant and demand of efficiently protecting cooling stave, and the blast-furnace tuyere mat structure that meets various blast furnaces longevity, high yield needs.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of blast-furnace tuyere mat structure, comprise ring-type furnace wall, described furnace wall is built by laying bricks or stones and is formed by multilayer fritter corundum brick, and it is large that the outer diameter of described furnace wall becomes from top to bottom successively, the thickness range of described furnace wall is 735mm-945mm, and the altitude range of furnace wall is 400mm-550mm.
The fritter corundum brick of adjacent two layers forms for overlapping occlusal masonry.
Described furnace wall is built by laying bricks or stones and is formed by 4-10 layer fritter corundum brick.
Fritter corundum brick outer ring, upper strata, described furnace wall is provided with chamfering.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model blast-furnace tuyere mat structure comprises ring-type furnace wall, and described furnace wall is built by laying bricks or stones and formed by multilayer fritter corundum brick, simple in structure; It is large that the outer diameter of described furnace wall becomes from top to bottom successively; the thickness range of described furnace wall is 735mm-945mm; the altitude range of furnace wall is 400mm-550mm; adopt furnace wall to increase thickening design; in order to meet the thermal zone high insulation of blast furnace, low heat conduction, resistance to erosion, corrosion-resistant and efficiently protect cooling stave demand, and the needs that meet various blast furnaces longevity, high yield.
2, structurally, the fritter corundum brick of the utility model adjacent two layers forms for overlapping occlusal masonry, reasonable in design, and easily operation is implemented; According to body of heater volume size, described furnace wall can be built by laying bricks or stones and be formed by 4-10 layer fritter corundum brick, meets the Production requirement of various blast furnaces.
3, to sum up; it is simple in structure, reasonable in design for the utility model blast-furnace tuyere mat structure, can meet the thermal zone high insulation of blast furnace, low heat conduction, resistance to erosion, the corrosion-resistant and demand of efficiently protecting cooling stave; and the needs that meet various blast furnaces longevity, high yield, be suitable for promotion and implementation.
