Abstract

The utility model relates to the structural improvement of a fireproof liner brick for a converter, an electric cooker or a steel ladle, solving the problems that existing liner bricks are laid flat during the fabrication process and are arranged flat when being used during construction, and the layers are not evenly compacted, so clearances exist between the layers, which leads to the leakage of the molten steel. The fireproof liner brick is characterized in that the four ridges between the top face and the underside of a skew brick are arranged to be longer than the four ridges between the two bevels. The fireproof liner brick has the advantages that the fireproof liner brick is laid flat during fabrication process and when in use, the liner brick is vertically laid and the clearances between layers are ensured by dies, thus reducing clearances; therefore the molten steel is not easy to leak.

Description

Converter, electric furnace, ladle refractory lining brick

Technical field:

The invention is that the planform of refractory material lining brick that converter, electric furnace, ladle are used is improved.

Background technology:

Converter before, electric furnace, used its planform of refractory material lining brick of ladle is to go up four rib height between end face and the following end face less than boring the horizontal digonous length in bottom surface, the awl bottom surface constitutes horizontal rectangle, vertex of a cone face is less than the awl bottom surface, constitute oblique brick body, be to use and bore the bottom surface when making oblique brick body, vertex of a cone face, two contour frame moulds that the inclined-plane matches, refractory material is dosed in contour frame mould, manual beating in fact made, real irregular because of manually beating, thickness does not wait, and when thorough building, is that lining brick accumbency use is promptly flat thorough, therefore there is not the gap because of thickness does not wait between layer and the layer, can causes the molten steel seepage; Because the awl bottom surface becomes horizontal rectangle, the inapplicable stove inside lock of long rib must be changed difform lining brick, therefore needs difform frame mould, has therefore strengthened manufacturing cost.

Summary of the invention:

The purpose of the invention provide a kind of flat beat upright thorough, easy to leak molten steel not, converter, electric furnace, the ladle refractory lining brick of reduction manufacturing cost; The purpose of the invention is to realize by following technical scheme: converter, electric furnace, ladle refractory lining brick, comprise oblique brick body, tiltedly the last end face (3) and the four rib length between the bottom surface (6) of brick body are made greater than four rib length between two inclined-planes (2,5).

The advantage of the invention: be to adopt the flat manual real manufacturing of beating of crouching equally when making this oblique brick body, frame mould four limits of being adopted are last end face and the bottom surfaces with oblique brick body, the awl bottom surface, the mould that vertex of a cone face matches and constituted on four sides, two big planes, four rib height do not wait during flat crouching, refractory material is inserted in the frame mould, artificial beating in fact, but be two big flat incline planes to be erect use when using, be vertical thorough building, this vertical thorough building, reduce in the gap between layer and the layer, not the easy to leak molten steel, be to guarantee by frame mould, and the gage distortion during flat beating do not influence layer and layer between the gap; Because when upright thorough, awl bottom surface transverse edge is short, is adapted to thorough the building in stove fillet place, does not need the oblique brick body of more difformity, reduces the frame mould shape, therefore cuts down finished cost.

Description of drawings:

Fig. 1 be at present commonly used flat crouch make, the flat thorough converter of building of crouching, electric furnace, ladle be with refractory lining brick planform schematic diagram;

Fig. 2 is converter, electric furnace, ladle refractory lining brick planform schematic diagram.

The specific embodiment:

Converter, electric furnace, ladle refractory lining brick comprise oblique brick body, and tiltedly the last end face 3 and the four rib length between the bottom surface 6 of brick body are made greater than four rib length between two inclined-planes 2,5.

Promptly bore the transverse edge length of the transverse edge length of bottom surface 1 greater than vertex of a cone face 4, constitute the vertical shape in big inclined-plane, two sides, with the refractory lining brick of this planform when upright thorough, not can because of flat crouch beat real gage distortion cause layer and layer between excesssive gap, molten steel is easy to leak not.

Claims

1, converter, electric furnace, ladle refractory lining brick comprise oblique brick body, it is characterized in that the last end face (3) of oblique brick body and four rib length between the bottom surface (6) make greater than four rib length between two inclined-planes (2,5).
