Further, the upper portion of locating piece is provided with the bolt hole with locating bolt looks adaptation.

Advantageous effects

The utility model provides a kiln mouth combined brick, which has the following beneficial effects compared with the prior art:

1. when the kiln mouth is fired, the heat-resistant heat-preserving piece is arranged on the brick body, so that multiple heat-insulating effects can be achieved in the kiln mouth, a large amount of heat loss in the kiln mouth is prevented, the heat-resistant capability is high, and the firing effect of the kiln mouth on a workpiece can be improved.

2. According to the combined brick for the kiln mouth, the two brick bodies are combined and spliced through the positioning blocks and the positioning bolts, so that the stability of the spliced combined brick is ensured, the loosening and detachment are not easy to occur, and the overall stability of the kiln mouth can be improved.
