1、Thermotechnical materials are all made of light alumina fiber products that piece together; the supporting structure is made of corundum, which will not crack, nor collapse.
2. Furnace chamber is sealed with a step-style convex and concave seal, which guarantee the tightness.
3. The load bearing board is made of corundum-mullite, with corundum-mullite buried at the bottom, to effectively bear load and to prevent the board from sinking.
4. The load bearing platform can be shifted out manually or with electricity, which is convenient for unloading products, and significantly reduces the strength of workers.
