Description of experimental electric furnace structure

1. The furnace body is assembled by welding section steel and steel plate.

2. Furnace lining is made of special-shaped refractory materials, thermal insulation materials, etc. The furnace bricks are made of corundum mullite, and the insulation layer is made of alumina hollow balls +1500 mullite poly light +1300 mullite poly light +1260 ceramic fiber; the distribution of each layer is optimized by calculation to ensure the fire resistance and heat preservation performance. There is a certain degree of strength.

3. The joints of furnace shell disassembly are sealed with silicon rubber, and the furnace mouth is cooled by water to protect the silicon rubber seals at the furnace mouth. The furnace mouth is equipped with intake and exhaust ports, drainage ports,

4. The air supply system consists of flow adjustment (0.16-1.6m3/h), pressure monitoring (0.16-1.6kpa), and pressure reducing valve. Valves, pipelines, etc. The gas supply source enters the electric furnace through a pressure reducing valve and a gas flow meter. The air inlet is set at the top of the electric furnace, and the exhaust and drainage are set at the bottom of the electric furnace.

5. The thermocouple adopts B index number and is installed on the top of the furnace.
