2. Prepare some cement bricks. Of course, you can also find other hard and high-temperature resistant materials. Some cement bricks need to be split in half because the back will be used to build walls.
3. Start building the foundation of the kiln. Level is very important. With the level, you can make a basic level.
4, slowly build by laying bricks or stones, cement brick piece by piece in the joint filled with cement mortar.
5, find a piece of angle iron, used as a brick bridge, prepare wood square, 10 steel bar, pour cement mortar, about 80cm began to use wood square scaffolding.
6, spread the template on the wood square, and cut off the reserved steel bar at the edge of the cement brick, discharge the steel bar in the reserved steel bar, and reserve a gray hole, stir and pour the cement, arrange the refractory bricks and leave a gray hole.
7. Start to build the main structure, side walls and kiln tail, and calculate the height, in which the height of kiln mouth is about 63% of the overall height.
8. Then start making arched roofs. It's best to make a wooden template to increase efficiency, and build by laying bricks or stones layer by layer. Because my distance is not accurate, the gap is a bit big.
9, kiln mouth joint processing, brick molding with diamond saw blade.
10, front of kiln mouth, kiln mouth support, chimney, shape of chimney after molding, and internal structure of kiln.
1 1, fixed outside the kiln body with wooden formwork, and laid with iron net to prevent the kiln body from cracking.
12, then pour refractory cement on the iron net to reinforce it into thermal insulation layer, and sandwich rock wool for thermal insulation.
13. Finally, firing the high-temperature barbecue kiln body can quickly strengthen the kiln body. Of course, you can bake bread here, and the oven is finally finished.
