1. The main body of the equipment adopts double-layer sheet metal structure. Fans are installed between the two-layer sheet metal to strengthen convection, and the temperature of the external surface of the equipment is low.
2. The furnace door and top are sealed with high temperature silicone rubber, and the furnace door is equipped with water cooling system. The furnace body is provided with air inlet, air outlet and vacuum outlet.
3. The furnace material is made of high-quality alumina polycrystalline fiber by vacuum adsorption. Compared with the traditional refractory material, the furnace material has lower heat loss, superior heat preservation effect and more than 50% energy saving.
