The utility model discloses a set up flame retardant coating and insulating layer to set up the through -hole between flame retardant coating and insulating layer, can make formation heat circulation way between the brick body of piling up mutually, and then make single the brick body the concentrated condition of heat can not appear, reduced thermal conduction, set up the arc wall in the external cambered surface of brick, reduced the area of contact of the brick body with the kiln inside lining, further reduced heat conducting area, set up the arch in the internal cambered surface of brick, can reduce the friction of sintered material and the internal cambered surface of brick, improved brick body structural strength, prolonged the life of the brick body.
Description
Technical field
The utility model relates to fire resisting material field, particularly relates to a kind of low heat conduction refractory brick.
Background technology
Refractory brick is a kind of refractory material with definite shape and size, is widely used in being lining with in kiln, can play good insulation, heat insulation effect.The high fire resistance that existing refractory brick has is widely used, but in the kiln that some flame temperatures are very high, on the one hand, the product of sintering can with refractory brick surface contact friction, the time has grown the damage that can cause refractory brick; The heat-proof quality of refractory brick does not reach requirement on the other hand, and the heat of its conduction is relatively large, and then makes the temperature of feed entrance too high, and operating personnel, when carrying out feeding, easily occur scalding, threaten the personal safety of operating personnel; Therefore need a kind ofly to reduce heat transfer and the refractory brick of rub resistance.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of low heat conduction refractory brick, has the advantages that structural strength is high, heat transfer is low, heat-proof quality is good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of low heat conduction refractory brick, comprise the brick body of arcuate structure, described brick body comprises flame retardant coating and thermal insulation layer, described brick body middle part offers the through hole of several through brick body two sides along radian direction, described through hole, between flame retardant coating and thermal insulation layer, the extrados of described brick body has deep-slotted chip breaker, and brick body intrados is evenly equipped with some semi-cylindrical hills.
Further, the upper and lower two ends, a side of described brick body are provided with projection, and the corresponding described projection in upper and lower two ends, another side is provided with groove, described groove and projection suitable.
Further, the cross sectional shape of described projection and groove is trapezoidal.
Further, described through hole is two, and its cross sectional shape is the one in rectangle, circle and triangle.
Further, described flame retardant coating material is cenosphere, is added with sillimanite in described thermal insulation layer.
Further, described brick body intrados is coated with fire resistant coating.
The advantage that the utility model has and good effect are: by arranging flame retardant coating and thermal insulation layer, and through hole is set between flame retardant coating and thermal insulation layer, can make to form heat passage between the brick body piled up mutually, and then the situation making single brick body there will not be heat concentrated, reduce the conduction of heat; Deep-slotted chip breaker is set in brick external cambered surface, decreases the contact area of brick body and inner lining of kiln, reduce further heat conducting area; Projection is set at brick body intrados, the friction of agglomerated material and brick body intrados can be reduced, improve brick laying structure intensity, extend the service life of brick body.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is illustrated:
As Figure 1-3, the utility model provides a kind of low heat conduction refractory brick, there is heat transfer low, structural strength is high, the advantage of long service life, it specifically comprises the brick body 1 of arcuate structure, brick body 1 comprises flame retardant coating 11 and thermal insulation layer 12, wherein flame retardant coating 11 is arranged on the intrados side of brick body 1, near the side of kiln burning, thermal insulation layer 12 is arranged on the extrados side of brick body 1, fit with inner lining of kiln, offer the through hole 2 of several through brick body 1 two sides along radian direction in the middle part of brick body 1, this through hole 2 is between flame retardant coating 11 and thermal insulation layer 12, for the circulation of heat in brick body 1, when multiple brick body 1 is piled up together, all through holes 2 can form a circulation passage, heat in brick body 1 can be circulated in this passage, and then decrease the heat transmission of brick body 1 and kiln, the extrados of brick body 1 has deep-slotted chip breaker 3, and the setting of this deep-slotted chip breaker 3 is to reduce brick body 1 and the contact area of inner lining of kiln, also with regard to the relative area decreasing heat trnasfer, reduce further the conduction of heat, the intrados of brick body 1 is evenly equipped with some semi-cylindrical hills 4, this projection 4 is paved with the intrados of whole brick body 1, and then when carrying out material sintering, the material of sintering can not directly contact with the intrados of brick body 1, also just decrease the friction of material and intrados, and then extend the service life of brick body 1.
As shown in Figure 1, a side upper/lower terminal of brick body 1 is provided with projection 5, and the corresponding described projection 5 of another side upper/lower terminal is provided with groove 6, and this groove 6 is suitable with projection 5, and then is convenient to pile up when piling up between brick body 1.Preferably, the cross sectional shape of projection 5 and groove 6 is set to trapezoidal, be convenient in projection 5 quick insertion groove 6, effectively can improve the speed and quality of piling up, relative to existing by artificially locating the mode of piling up, further reduce because of people be pile up defective cause pile up place loosen.
In the present embodiment, through hole 2 is set to two, and its cross sectional shape can be one or more in rectangle, circle and triangle.The present embodiment selects square-section.
Further, the material of flame retardant coating 11 is cenosphere, is added with sillimanite in thermal insulation layer 12, ensure that fire resistance and the heat-proof quality of refractory brick.
As preferred technical scheme, the intrados of brick body 1 is coated with fire resistant coating, to improve fire-resistant effect.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
