Abstract

The utility model provides an inner ring wall brick for a dry quenching furnace. A boss is arranged at one end of the inner ring wall brick; a groove is formed in the other end of the inner ring wall brick; a rib is arranged on the upper surface of the inner ring wall brick; and a trench is formed in the lower surface of the inner ring wall brick. The height of the boss is the same as the depth of the groove, and the boss is shorter than the groove by 4 to 6mm. During building of an inner ring wall, two adjacent inner ring wall bricks are embedded and built through the boss and the groove, the inner ring wall bricks on upper and lower layers are meshed with each other through the rib and the trench in the upper and lower surfaces of the inner ring wall bricks, mutual interlayer constraint is formed, the interlayer connection strength is improved, the hoop thermal stress of the inner ring wall is absorbed through free expansion between the bricks, and the stress on a wall body is reduced, so that the strength of the inner ring wall is effectively improved, the service period and production period of the dry quenching furnace are prolonged, the maintenance cost of the dry quenching furnace is reduced, and the smoothness of production is ensured.

Description

A kind of dried ringwall brick in the stove that puts out

Technical field

The utility model belongs to technical field of refractory materials, particularly a kind ofly builds the dried interior ringwall brick that stove is used that puts out by laying bricks or stones.

Background technology

Driedly put out interior ringwall brick that stove builds usefulness by laying bricks or stones because the defective in the design, cause the dried ringwall intensity of putting out in the stove not high, ringwall cave-in accident in frequent the appearance has not only increased maintenance cost, has strengthened refractory consumption rate, has shortened the life cycle of interior ringwall; And dried the put out utilization ratio of stove and carrying out smoothly of dry coke quenching production have directly been influenced.And if want to prolong dried work-ing life of putting out stove, just must to produce load be cost to sacrifice, thus production efficiency caused lowly and the increase of production cost.

Summary of the invention

The utility model aims to provide and a kind ofly can effectively strengthen the dried intensity of putting out ringwall in the stove, and stressed excessive the causing of ringwall caved in avoiding, and prolongs the dried stove life cycle of putting out, the dried interior ringwall brick of stove that puts out that reduces production costs.

For this reason, the utility model has been taked following technology solution;

A kind of dried ringwall brick in the stove that puts out is characterized in that, has boss in the middle of described interior ringwall brick one end, is provided with groove in the middle of the other end, has one fin in the middle of the upper surface, is provided with one groove in the middle of the lower surface.

Described boss height is identical with depth of groove, and land length is than the little 4-6mm of groove length.

Described fin and trench cross-section are semicircular arc; The fin radius-of-curvature is 12-16mm, rises 10-14mm; Groove radius of curvature is 20-24mm, groove depth 11-15mm.

Building method of the present utility model and beneficial effect are:

When interior ringwall is built by laying bricks or stones, build by laying bricks or stones to inlay between boss and the groove between adjacent two interior ringwall bricks, in the levels between the ringwall brick by the fin of interior ringwall brick upper and lower surface and being meshing with each other of groove, mutual restriction between form layers and the layer, strength of joint between enhancement layer and the layer, by the free expansion between brick and the brick, the thermal stresses of ringwall hoop in absorbing, reduce the stressed of body of wall, thereby the intensity of ringwall in effectively improving, prolong the dried stove that puts out and use and the production cycle, reduce the dried maintenance cost of putting out stove, guarantee the direct motion of producing.

Description of drawings

Fig. 1 is the dried interior ringwall brick front view of stove that puts out.

Fig. 2 is the dried interior ringwall brick vertical view of stove that puts out.

Among the figure: interior ringwall brick 1, groove 2, groove 3, boss 4, fin 5.

Embodiment

By accompanying drawing as seen, be that a degree of depth is 80 mm, length 200mm and the rectangular recess 2 that connects interior ringwall brick 1 thickness in the middle of the upper end of ringwall brick 1 in the utility model; Corresponding with groove 2, the middle rectangle boss 4 that is provided with height 80 mm, a length 195mm in the lower end of interior ringwall brick 1.Is provided with radius-of-curvature 14mm one in the middle of the upper surface of interior ringwall brick 1 (internal surface), rises 12mm, the cross section is the fin 5 of semicircular arc; Corresponding with fin 5, in the middle of the lower surface (outside surface) of interior ringwall brick 1, then be provided with radius-of-curvature 22mm one, groove depth 13mm, cross section are the groove 3 of semicircular arc.

Claims
