Introduction to Resistance Furnaces
Resistance furnaces are heating devices that generate heat through the principle of electrical resistance. When an electric current passes through a resistive material, electrical energy is converted into heat energy. These furnaces are widely used in various industries such as metallurgy, ceramics, heat treatment, and materials research. They offer precise temperature control, high energy efficiency, and a clean heating environment, making them essential equipment for many manufacturing processes.
