Abstract
The utility model belongs to the technical field of components of a steel smelting furnace and relates to a tile structure for a permanent layer of a converter lining. The fireproof tile for the permanent layer of the furnace crown of the converter is made of magnesium materials, and a longitudinal section of the fireproof tile for the permanent layer of the furnace crown of the converter is in a right trapezoid shape, thereby preventing generating of cavities at the position of the furnace crown, prolonging service life of the converter lining and ensuring smooth production.
Description
Technical field
The utility model belongs to the parts technical field of smelting iron and steel stove, is specifically related to the converter lining permanent layer and uses brick laying structure.
Background technology
In the converter building process,, cause the bigger space of existence between furnace crown permanent layer magnesia brick and the furnace shell steel plate because furnace shell angle of inclination, furnace crown place is bigger.Conventional art is between permanent layer standard magnesia brick and furnace shell steel plate, to fill the space with magnesia powder; Because grate frequent in actual production produces friction; The magnesia powder of make filling runs off through the furnace shell air-vent gradually, begins to become flexible loosening continuous impact wear furnace shell of standard magnesia brick and magnesia carbon brick working lining after causing furnace crown part standard magnesia brick to lose support; Cause a large amount of fracture wear efflorescence of standard magnesia brick, and then form the furnace crown cavity.
CN2062814 discloses a kind of kiln lining refractory brick that is used for taper circular section high temperature kiln; Its shape is that the horizontal cross-section is the hexahedron of isosceles trapezoid; The plane that two trapezoidal little limits of last lower plane constitute is a vertical plane; Also can be the plane of inclination certain angle, be used to the whole taper circular section part of inlaying kiln.
Summary of the invention
The utility model provides a kind of BOF Hood permanent layer refractory brick to the deficiency of prior art, mainly is to produce cavity, furnace crown position in order to prevent, improves converter lining service life, ensures to produce and carries out smoothly.
The technical scheme that the utility model adopts is: a kind of BOF Hood permanent layer refractory brick, be hexahedron structure, and adopt magnesian to process; Content of magnesia is not less than 91%, it is characterized in that: five faces of BOF Hood permanent layer refractory brick are for facing directly, and a face is the inclined-plane; The height h of BOF Hood permanent layer refractory brick is 95～160mm; Thickness δ is 100～120mm, and the wide a of upper surface is 50～80mm, and following table face width b is 100～160mm.
The height h of preferred BOF Hood permanent layer refractory brick is 149mm, and thickness δ is 115mm, and the wide a of upper surface is 60mm, and following table face width b is 147mm.
The beneficial effect of the utility model is: can prevent to produce furnace crown position cavity, improve converter lining service life, ensure carrying out smoothly of producing.

The specific embodiment
As shown in the figure, when the furnace crown position was built in converter by laying bricks or stones, BOF Hood permanent layer fire brick layer 3 used the BOF Hood permanent layer refractory brick of the utility model; BOF Hood permanent layer refractory brick is hexahedron structure; The employing magnesian is processed, and (MgO is magnesian chemical formula to magnesia, and according to being: " practical chemistry handbook the 46th page table the 1st is listed as the 21st row; Publishing house is: the chemical and applied chemistry publishing centre of Chemical Industry Press) content is not less than 91%; Its front, the left side, the right side, top, following five faces are for facing directly, and the back is the inclined-plane, left-right symmetric.BOF Hood permanent layer refractory brick height h is 149mm, and thickness δ is 115mm, and the wide a of upper surface is 60mm, and the wide b of table is 147mm below.Inclined-plane, BOF Hood permanent layer refractory brick back used magnesia chamotte 2 to join with furnace shell 1 when converter was built by laying bricks or stones, and chamotte is full, and BOF Hood permanent layer refractory brick front is faced directly with magnesia carbon brick working lining 4 and joined.
Claims (2)
1. a BOF Hood permanent layer refractory brick is hexahedron structure, adopts magnesium oxide material to process; It is characterized in that: five faces of BOF Hood permanent layer refractory brick are for facing directly; A face is the inclined-plane, and the height h of BOF Hood permanent layer refractory brick is 95～160mm, and thickness δ is 100～120mm; The wide a of upper surface is 50～80mm, and following table face width b is 100～160mm.
