Application of Electric Heating Furnace
TIME: 2021/2/23

 Under the condition of stable power supply, the electric heating furnace has many advantages over the fuel furnace, especially it does not need fuel storage, transportation, post-combustion ash and huge flue gas emission and purification devices, so it has the advantages of small space occupation, simple installation, convenient operation and management, and no pollution such as CO2 and SO2. At the same time, it is easy to control and guarantee the heating quality, and can be integrated, local or table as needed. The surface is heated so that the quality is good and the thermal efficiency is high.

Because of the above characteristics, the electric heating furnace is suitable for the manufacture of advanced materials and components, and has good energy-saving effect. Therefore, it has been widely used in the electromechanical processing and assembly industry of automobiles, motors, household appliances and electronics. In the future, with the steady development of electric power industry and the expansion of processing industry and processing heightening and proportion, resistance furnaces, induction furnaces and electron beam heating will continue to develop; in high energy consumption sectors such as iron and steel industry, metal products and kiln industry, with the development of deep processing, high quality products and ceramic materials, as well as the control of energy saving and CO2, the proportion of electric heating will also expand. In addition, the use of microwave ovens and far-infrared heating ovens in chemical, textile and food industries will also increase, while in civil areas, microwave ovens and heat pumps will also be applied and expanded.
Generally classified as follows:
1. Machinery industry is used for heating raw materials, blanks and mechanical parts. Such as billet heating before rolling and forging heating.
2. Heat treatment of mechanical parts and semi-finished products to improve their mechanical properties, such as quenching, tempering, annealing, gas carburizing, nitriding, etc.
3. Melting of low melting point metals and heating of ceramic glass industry.
4. Detection of physical properties of inorganic materials.
5. Scientific research in the laboratory.
