The purpose and working principle of box-type resistance furnace
A box-type resistance furnace is an industrial device that uses the heat generated by the passage of electric current through a resistive material to heat workpieces or materials. Its working principle is based on Joule's law, which states that heat is generated when an electric current passes through a conductor.
Applications: Box-type resistance furnaces are mainly used in the following fields:
Heat Treatment Processes: Annealing, normalizing, quenching, and other processes for metal materials to improve their properties.
Ceramics and Materials Sintering: Used for sintering ceramics, refractory materials, electronic components, and calcining powder metallurgy materials.
Industrial Experiments: Involving scientific research experiments such as material degassing, quality inspection, and the development of special materials.
High-Temperature Treatment: High-temperature heating or melting of low-melting-point metals in chemical, mechanical, and metallurgical fields.
Working Principle: The resistance furnace achieves heating through the following methods:
Heating Element: Using resistance wire, silicon carbide rods, or silicon molybdenum rods as heating elements, heat is generated when electricity is applied.
Temperature Control: Equipped with intelligent instruments to monitor and adjust the temperature in real time, ensuring heating uniformity and accuracy. Heating methods: Available in natural atmosphere and atmosphere (such as nitrogen or argon protection) to meet different process requirements.
