Embodiment Construction

[0009] The specific technical solutions of the present invention are described in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, the heat-insulating composite refractory brick includes a silica brick layer 1 on the top layer, a filling block 3 in the middle and a phosphate brick layer 4 on the lower layer. The lower surface 5 of the phosphate brick layer 4 is a concave-convex surface. There is also a groove 6 in the recess, corresponding to the upper silica molybdenum layer 1, there is a draw-in groove 7, and a jumper 8 is also included, and the two ends of the jumper 8 are respectively embedded in the groove 6 and the draw-in groove 7.

[0011] There are aluminum silicate fibers 2 between the filling block 3 and the phosphate brick layer 4 .

[0012] The silica brick layer 1, the middle filler block 3 and the phosphate brick layer 4 of the lower floor are fixed together by the clip spring 8, which is not easy to come off. The lower surface 5...

Abstract

The invention relates to a refractory brick, in particular to a heat-insulated composite refractory brick. The heat-insulated composite refractory brick comprises a top guimo brick layer, a middle filled block and a lower phosphate brick layer, wherein the lower surface of the phosphate brick layer is a concave-convex surface, grooves are formed in the concave portions, and the guimo brick layer is provided with clamping grooves corresponding to the grooves; the heat-insulated composite refractory brick further comprises clamping springs, and the two ends of each clamping spring are embedded into the corresponding groove and the corresponding clamping groove. According to the heat-insulated composite refractory brick, the guimo brick layer, the middle filled block and the lower phosphate brick layer are fixed together through the clamping springs and are not prone to fall off; the lower surface of the phosphate brick layer is the concave-convex surface and can be an uneven surface formed by a corrugated surface and broken lines in multiple shapes for reducing heat expansion deformation of the surface of the phosphate brick layer, increasing the bonding surface of the phosphate brick layer and a bonding agent and decreasing the possibility that the phosphate brick layer falls off due to deformation between the phosphate brick layer and the bonding agent.

Description

technical field [0001] The invention relates to a refractory brick, in particular to a heat-insulating composite refractory brick. Background technique [0002] The heat-insulating composite refractory bricks commonly used at present usually include a heat-insulating layer, and the heat-insulating layer is connected with the kiln body to isolate the heat in the kiln and reduce damage to the kiln body. [0003] The existing heat insulation layer is connected to the brick body through an adhesive, which is extremely easy to fall off, thereby failing to achieve the effect of the heat insulation layer and shortening the service life of the product. Contents of the invention [0004] Aiming at the above technical problems, the present invention provides a heat-insulating composite refractory brick whose heat-insulating layer is not easy to fall off. The specific technical solution is: [0005] Heat-insulating composite refractory bricks, including silica brick layer on the top...
