Sapphire Annealing Furnace
This lifting furnace adopts an electric lifting structure, and the furnace material is all vacuum-formed high-purity alumina polylight material. It has high use temperature, small heat storage capacity, resistance to rapid heating and cooling, no cracks, no slag, and good thermal insulation performance. Electric hydraulic lifting system, furnace bottom door. It is widely used in production and experiments in the fields of ceramics, metallurgy, sapphire annealing, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, building materials, etc.
