Description
Technical Field
The utility model relates to a magnesia carbon brick, concretely relates to heterotypic magnesia carbon brick.
Background
Magnesia carbon bricks are produced by using a high-melting point basic oxide magnesium oxide (melting point 2800 ℃) and a high-melting point carbon material which is difficult to be infiltrated by slag as raw materials, and adding various non-oxide additives. The non-burning carbon composite refractory material is formed by combining carbon binders. The magnesia carbon brick is mainly used for the inner liners of converters, alternating current electric arc furnaces and direct current electric arc furnaces, slag lines of ladles and other parts. As a composite refractory material, the magnesia carbon brick effectively utilizes the strong slag corrosion resistance of magnesia and the high thermal conductivity and low expansibility of carbon, and compensates the biggest defect of poor spalling resistance of magnesia. However, the existing magnesia carbon brick is limited by materials, the shape is fixed, the magnesia carbon brick is basically of a standard cuboid structure, the structure of the magnesia carbon brick is weak in pressing force, easy to separate, fall off and damage, poor in fitting property, and cannot completely meet the existing production requirements, and the falling risk is caused after the magnesia carbon brick is used for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the single shape of the magnesia carbon brick can not meet the requirement of the existing production equipment, and providing the magnesia carbon brick with simple structure, compact design, convenient splicing and good laminating property.
In order to solve the technical problem, the utility model provides a special-shaped magnesia carbon brick, which comprises a brick body, wherein the upper surface of the brick body is provided with a first arc-shaped boss, the lower surface of the brick body is correspondingly provided with a first arc-shaped groove, and one side surface of the brick body is provided with a second arc-shaped boss; the other side of the brick body is provided with a second arc-shaped groove corresponding to the position of the second arc-shaped boss, the first arc-shaped boss is embedded with the first arc-shaped groove in shape, and the second arc-shaped boss is embedded with the second arc-shaped groove in shape.
The arc radius of the first arc-shaped boss is 1290 and 1490 mm.
The arc radius of the first arc-shaped groove is 1290 and 1490 mm.
The arc radius of the second arc-shaped boss is 230 and 250 mm.
The arc radius of the second arc-shaped groove is 230 mm and 250 mm.
The utility model discloses simple structure, the packing force is strong, is difficult for droing and damaging. The utility model discloses a between the polylith brick body first arc boss and first arc recess to and the combined design of second arc boss and second arc recess, make resistant firebrick's assembly structure more stable, in addition, this type of brick type still can conveniently be transferred and built by laying bricks or stones, and work efficiency obviously improves.
The utility model discloses simple structure, the packing force is strong, is difficult for droing and damaging. When the assembly, polylith magnesia carbon brick body makes up the collocation, can make the assembly structure of resistant firebrick more stable, and in addition, this type of brick type still can conveniently be transferred and built by laying bricks or stones, and work efficiency obviously improves.
