The utility model has the advantages that: the arranged reinforcing block and the steel fiber improve the integral tensile strength of the prefabricated block; the fire resistance and the heat insulation performance of the multi-layer castable layer are improved.
Description
Technical Field
The utility model belongs to the heat preservation stove refractory material field especially relates to a high-alumina type heat preservation castable prefabricated section.
Background
At present, the traditional method of the refractory casting precast block for the heat preservation furnace is to cast a material with a specific gravity through a mould, the compression strength of the refractory casting precast block is high, but the tensile strength and the rupture strength of the refractory casting precast block are relatively low; with the poor fire resistance of the precast block, the phenomenon of corner collision easily appears during transportation or installation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high alumina type heat preservation pouring material prefabricated section improves its tensile strength, improves its fire resistance, effectively prevents the phenomenon that the edge from crashing, is particularly suitable for being used in the holding furnace.
The technical scheme of the utility model is that: a high-aluminum type heat-insulating castable precast block comprises a precast block body, wherein the precast block body comprises an upper light castable layer, a middle heavy castable layer and a lower heavy castable layer which are sequentially arranged from top to bottom, the middle part of the precast block body is provided with round holes which are the same up and down, a plurality of steel fibers are arranged in the precast block body along the round holes, the steel fibers vertically and sequentially penetrate through the upper light castable layer, the middle heavy castable layer and the lower heavy castable layer,
the prefabricated section body four angles department in be equipped with the boss respectively, the boss be the L type, and establish at the prefabricated section body.
Furthermore, the middle heavy castable layer and the lower heavy castable layer are both made of aluminum silicate heavy refractory materials, and the upper light castable layer is made of aluminum silicate light refractory materials.
Furthermore, the steel fiber is wavy, and the fixity of the steel fiber on the precast block body is improved.
Furthermore, the precast block body is provided with a plurality of round holes which are the same up and down, and the distance between the two connected round holes is the same.
Furthermore, the precast block body is a square precast block or a round precast block.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the tensile strength of the whole precast block is improved by the arranged reinforcing blocks and the steel fibers; the fire resistance and the heat insulation performance of the multi-layer castable layer are improved.

Detailed Description
As shown in fig. 1, the technical scheme of the utility model is a high-alumina type heat preservation castable precast block, including the precast block body, the precast block body include from the top down and be equipped with light pouring bed of material 1 in proper order, well heavy pouring bed of material 2, heavy pouring bed of material 3 down, the same round hole 4 about the mid portion of precast block body is equipped with, the precast block this internal be equipped with a plurality of steel fibre 5 along round hole 4, steel fibre 5 vertical pass light pouring bed of material 1 in proper order, well heavy pouring bed of material 2, heavy pouring bed of material 3 down, four angles of precast block body in be equipped with boss 6 respectively, boss 6 be the L type, and establish at the precast block body internally.
In the embodiment, the middle heavy castable layer 2 and the lower heavy castable layer 3 are both made of aluminum silicate heavy refractory materials, and the upper light castable layer 1 is made of aluminum silicate light refractory materials.
In this embodiment, the steel fibers 5 are wavy, so as to improve the fixation of the steel fibers 5 on the precast block body.
In this embodiment, the precast block body is provided with a plurality of round holes 4 which are the same up and down, and the distance between two connected round holes 4 is the same.
In this embodiment, the precast block body is a square precast block or a circular precast block.
The working process of the example is as follows: when in use, the tensile resistance of the steel fiber reinforced concrete is improved due to the plurality of steel fibers 5 arranged among the upper light castable layer 1, the middle heavy castable layer 2 and the lower heavy castable layer 3; the arranged reinforcing blocks protect the corners of the reinforcing blocks; the fire resistance and the heat insulation performance of the pouring material layer are improved.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
