The series of muffle furnaces manufactured by our factory are renovated and upgraded products of old products, with integrated production and easy installation, making the temperature control accuracy of the electric furnace higher and more automated. Widely applicable to various laboratories, industrial and mining enterprises, scientific research units for element analysis and determination, as well as general small parts quenching, annealing, tempering and other heat treatment operations.

structural characteristics
The appearance of this series of resistance furnaces is rectangular, and the furnace shell is made of cold-rolled steel plates welded by folding. The working chamber is made of silicon carbide refractory material, and insulation material is used as the insulation layer between the furnace chamber and the furnace shell. In order to reduce the heat loss at the furnace mouth and improve the uniformity of temperature inside the furnace, a heat-resistant plate made of refractory material is installed on the inside of the furnace door
