Converts electrical energy into heat energy to heat the object. is a form of electric energy utilization. Compared with the general fuel heating, electric heating can obtain higher temperatures (such as arc heating, temperature up to 3,000 ℃ above), easy to realize temperature control and long-distance controls, on-board electric heating cups. The heated object can be kept at a certain temperature distribution as needed. Electric heating can be heated directly inside the body heat, thus high thermal efficiency, temperature, and can be based on heating process requirements, the realization of uniform heating or local heating (including surface heating), easy to achieve vacuum heating and control atmosphere heating. In the process of electric heating, the resulting exhaust gases, residues and soot are less, can be kept heating the body clean, do not pollute the environment. Therefore, electric heating is widely used in the fields of production, scientific research and testing. In particular, electric heating is used in the fabrication of single crystals and transistors, mechanical parts and surface quenching, ferroalloy smelting and man-made graphite. Cast copper heating plate manufacturers are widely used in household appliances, such as rice cookers, microwave ovens, electronic disinfection cabinets, hair dryer, electric irons and so on.
