[0019] The utility model provides a technical solution: Figure 1-4 As shown, in the present embodiment, a lightweight composite refractory brick for a heating furnace comprises a refractory brick body 1, a square through hole 2 is penetrated on one side of the refractory brick body 1, a heat insulating block 3 is embedded in the square through hole 2, a corrugated sound insulation block 4 is embedded in one side of the heat insulating block 3, a plurality of filling grooves 5 are opened on one side of the corrugated sound insulation block 4, and the plurality of filling grooves 5 are filled with graphene aerogel 6, wherein, by arranging the heat insulating block 3, the temperature inside the heating furnace can be isolated to prevent excessive heat loss, by arranging the corrugated sound insulation block 4, the noise can be reflected, and by arranging the graphene aerogel 6, the sound absorption effect can be improved and further sound absorption can be achieved.

[0020] like Figure 1 and Figure 2 As shown, a positioning block 7 is fixedly connected to the top of the refractory brick body 1, and a positioning groove 8 is provided at the bottom of the refractory brick body 1 and at the same vertical position as the positioning block 7. By providing the positioning block 7 and the positioning groove 8, positioning can be facilitated when stacking up and down, thereby improving the stacking efficiency.

[0021] like Figure 1-4 As shown, filling grooves 9 are provided at the top and bottom of the refractory brick body 1 to enhance the connectivity when connected by refractory cement.

[0022] like Figure 1-4 As shown, four trapezoidal butt joints 10 are fixedly connected to one side of the refractory brick body 1, and two trapezoidal butt grooves 11 are opened on the other side of the refractory brick body 1. The four trapezoidal butt joints 10 are slidably inserted into the two trapezoidal butt grooves 11 respectively, so that the two refractory brick bodies 1 can fit tightly together.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, fixing grooves 12 are provided at the edges of both sides of the refractory brick body 1 and at the trapezoidal butt joint grooves 11, so that the two refractory brick bodies 1 can be limited by refractory cement.

[0025] The utility model provides a lightweight composite refractory brick for a heating furnace, and the specific working principle is as follows:

[0026] When the refractory brick bodies 1 are stacked horizontally, the trapezoidal butt joint 10 on one of the refractory brick bodies 1 is docked with the trapezoidal butt groove 11 on the other refractory brick body 1. After the docking is completed, refractory mud is filled in the fixing groove 12, and the trapezoidal butt joint 10 and the trapezoidal butt groove 11 are limited. When stacking up and down, the two refractory brick bodies 1 can be quickly positioned by the positioning block 7 and the positioning groove 8.
