Abstract

The utility model belongs to the field of steel ladle edge fireproof parts in the metallurgical industry and particularly relates to a steel ladle edge forsterite carbon brick. A forsterite carbon brick body (1) is a square structure body. The square structure body is a right-angle heptahedron formed by cutting off a corner of a cuboid through an inclined face (103) vertically. The length m of a bottom face (102) of the forsterite carbon brick body (1) is 210-250mm. The height h of the forsterite carbon brick body (1) is 200-230mm. A dip angle alpha of the inclined face (103) of the forsterite carbon brick body (1) is 30-65 degrees. Grooves (2) are formed in the upper surface (101), the bottom face (102) and the inclined face (103) of the forsterite carbon brick body (1). The brick is simple in structure and strong in pressing force, a slag line brick is not easy to fall, and high temperature expansion stress of a working lining can be effectively buffered.

Description

Steel ladle edge forsterite carbon brick

Technical field

The utility model belongs to metallurgy industry steel ladle edge refractory part field, relates in particular to a kind of steel ladle edge forsterite carbon brick.

Background technology

Ladle is the important devices of metallurgical industry, plays storage, the effect of transhipment molten steel, and the dual role that simultaneously also will carry out external refining, the length in ladle service life, not only be related to the consumption of refractory material, and the normal production that directly impact is made steel.

Major requirement to steel ladle edge in general steelmaking process has 2 points: (1) can compress the ladle slag line brick, prevents coming off and brickwork joint expansion of slag line brick; (2) buffering ladle working lining high-temperature expansion stress, for meeting above-mentioned requirements, the structural design of steel ladle edge is most important.At present, steel ladle edge structure substantially adopts horizontal baffle to add bag and combines along material, and this type of wraps along structure, and a little less than thrust, the bag that is attached to horizontal baffle is easy to separate, come off, damage along material, and then causes wrapping burning of wall, baffle plate.

The utility model content

The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and thrust is strong, and slag line brick difficult drop-off can effectively cushion the steel ladle edge forsterite carbon brick of working lining high-temperature expansion stress.

For solving the problems of the technologies described above, the utility model is to realize like this.

A kind of steel ladle edge forsterite carbon brick, its forsterite carbon brick body is the square structure; Described square structure is one jiao of right angle heptahedron of vertically being clipped rear formation by inclined-plane of cuboid.

As a kind of preferred version, the long m in bottom surface of forsterite carbon brick body described in the utility model is 210～250mm; The high h of described forsterite carbon brick body is 200～230mm.

As another kind of preferred version, the inclination angle a on forsterite carbon brick body described in the utility model inclined-plane is 30～65o.

Further, upper surface, bottom surface and the inclined-plane of forsterite carbon brick body described in the utility model are provided with groove.

The utility model is simple in structure, and by adopting square structure forsterite carbon brick, its thrust is strong, and slag line brick difficult drop-off can effectively cushion working lining high-temperature expansion stress.Inclined-plane in the square structure and the combining structure of oblique pressing plate, make bag significantly strengthen along regional thrust is strong.

The accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection domain of the present utility model not only is confined to the statement of following content.

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is the utility model practical set figure.

In figure: 1, forsterite carbon brick body; 2, groove; 101, upper surface; 102, bottom surface; 103, inclined-plane; 3, oblique pressing plate; 4, slag line brick; 5, involucrum.

The specific embodiment

As shown in Figures 1 and 2, a kind of steel ladle edge forsterite carbon brick, its forsterite carbon brick body 1 is the square structure; Described square structure is one jiao of right angle heptahedron of vertically being clipped rear formation by inclined-plane 103 of cuboid.

The long m in bottom surface 102 of forsterite carbon brick body 1 described in the utility model is 220mm; The high h of described forsterite carbon brick body 1 is 210mm.

Forsterite carbon brick body 1 103 inclination angle, inclined-plane a described in the utility model is 65o.

Build by laying bricks or stones for ease of transhipment, improve and build efficiency by laying bricks or stones, the upper surface 101 of forsterite carbon brick body 1 described in the utility model, 102Ji inclined-plane, bottom surface 103 are provided with groove 2.Shown in Figure 2,3 is oblique pressing plate; 4 is the slag line brick; 5 is involucrum.The utility model is the extrusion effect with forsterite carbon brick inclined-plane 103 by oblique pressing plate 3, has avoided coming off and brickwork joint expansion of slag line brick slag line brick.

The utility model Forsterite products has very high refractoriness under load, the goods that add magnesia start deformation temperature and can reach 1650～1700 ℃, even higher, the ability of Forsterite products opposing melt oxidation iron is stronger, there is certain resistance to heat shocks, ability with certain alkali resistance slag, this is all the not available condition of magnesia carbon brick for good heat insulating.

Be understandably, above about specific descriptions of the present utility model, only for the utility model is described, and not be limited to the described technical scheme of the utility model examples of implementation, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
