Abstract
The invention discloses a low-heat-conductivity refractory brick. The refractory brick comprises a refractory layer and a thermal insulation layer, wherein the thermal insulation layer and the refractory layer are integrated through pressing; the thermal insulation layer is provided with through holes which penetrate the end faces on the two sides of the thermal insulation layer; the end face on one side of the thermal insulation layer is provided with grooves; the end face on the other side of the thermal insulation layer is provided with bumps which are correspondingly matched with the grooves. The refractory brick has the advantages of better heat dissipation performance and longer life.
Description
Technical field
The present invention relates to a kind of low heat conduction refractory brick.
Technical background
Refractory brick conventional in rotary kiln generally includes flame retardant coating and heat-insulation layer, flame retardant coating face side towards the fire, heat-insulation layer towards building brick, for thermal insulation protection.But because heat-insulation layer heat dispersion is poor, easy expanded by heating, causes the faying face of heat-insulation layer and flame retardant coating to be torn, shortens the life-span of refractory brick in high temperature environments.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of low heat conduction refractory brick, and have better heat dispersion, the life-span is longer.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of low heat conduction refractory brick, comprise flame retardant coating and heat-insulation layer, described heat-insulation layer and flame retardant coating are by being suppressed into one, described heat-insulation layer is provided with the through hole of through heat-insulation layer both sides end face, one side end face of described heat-insulation layer is provided with groove, and the opposite side end face of described heat-insulation layer is provided with the projection with groove corresponding matching.
Preferably, the cross section of described through hole is rectangle.
Preferably, the quantity of described groove and projection is respectively two, and two grooves are arranged at the both sides up and down of through hole respectively.
Beneficial effect of the present invention is:
Adjacent refractory brick is connected with projection by groove, connect fastening between refractory brick, make the through hole of adjacent refractory brick be communicated with, heat-insulation layer carries out cross-ventilation by through hole, improves radiating effect simultaneously, thus the thermal and insulating performance of heat-insulation layer is got a promotion, heat-insulation layer expanded by heating degree alleviates, and heat-insulation layer and flame retardant coating faying face are not easily torn, and improve the service life of refractory brick, simultaneously through hole the quality that page alleviates refractory brick is set, reduce cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As shown in Figure 1, the present invention includes flame retardant coating 1 and heat-insulation layer 2, described heat-insulation layer and flame retardant coating are by being suppressed into one, described heat-insulation layer is provided with the through hole 201 of through heat-insulation layer both sides end face, one side end face of described heat-insulation layer is provided with groove 202, and the opposite side end face of described heat-insulation layer is provided with the projection 203 with groove corresponding matching.The cross section of described through hole 201 is rectangle, and the efficiently radiates heat area of rectangle is comparatively large and make the weight loss effect of refractory brick obvious.The quantity of described groove 202 and projection 203 is respectively two, and two grooves are arranged at the both sides up and down of through hole 201 respectively, and this structure makes to combine firmly between adjacent refractory brick, not easily gets loose.
Principle of the present invention:
Adjacent refractory brick is connected with projection by groove, connect fastening between refractory brick, make the through hole of adjacent refractory brick be communicated with, heat-insulation layer carries out cross-ventilation by through hole, improves radiating effect simultaneously, thus the thermal and insulating performance of heat-insulation layer is got a promotion, heat-insulation layer expanded by heating degree alleviates, and heat-insulation layer and flame retardant coating faying face are not easily torn, and improve the service life of refractory brick, simultaneously through hole the quality that page alleviates refractory brick is set, reduce cost.
Just preferred embodiment of the present invention is described above, but can not be interpreted as it is limitations on claims.The present invention is not only confined to above embodiment, and its concrete structure allows to change, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all belongs to the scope that claims of the present invention define.
