The selected heat treatment equipment should have high productivity, thermal efficiency, and low energy consumption while meeting the requirements of the heat treatment process. Usually, when there is sufficient quantity of products, using specialized equipment has the best energy-saving effect.
Measurement and Control Technology
The measurement and control technology of heat treatment equipment has made significant progress, mainly manifested in temperature measurement and control, atmosphere measurement and control, and process program control. New technologies are constantly being adopted, and advanced high-quality components and instruments are being developed one after another, which are widely used in heat treatment furnaces. Computer control has almost expanded to all fields.
Working Principle
When the current flows towards a heating coil that is wound into a ring or other shape (usually made of copper tube). As a result, a strong magnetic beam with instantaneous polarity change is generated within the coil. When a metal or other heated object is placed within the coil, the magnetic beam will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a corresponding large eddy current will be generated. Due to the presence of resistance within the heated object, a significant amount of Joule heat is generated, causing the object's temperature to rapidly rise. To achieve the goal of heating all metal materials.
