Heating furnace is a device that we often see in factories. By heating the material to make it plastic, heating steel and various non-ferrous metals to an appropriate temperature can change its mechanical properties and organizational structure. At this time, the metal can be deformed with a small pressure. For example, the deformation resistance of steel at high temperature is only 1/300 to 1/50 of that at normal temperature. Some metals or alloys are difficult to deform at room temperature and must be heated. Therefore, forging, steel rolling, hot stamping, drawing and other processes all need to use the plastic properties of metals at high temperatures for processing.
Different from drying equipment, the main purpose of heating furnace is not to heat general materials, but to heat metal products at high temperature without oxidation or less oxidation so that they can be further processed. With the development of science and technology, there are more and more types of heating furnaces. According to the heat source, there are fuel heating furnaces, resistance heating furnaces, induction heating furnaces, microwave heating furnaces, etc. Applications in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries.
Because of the unique characteristics of the heating furnace, various industrial products can be heated without manual operation, which greatly reduces the safety and the possibility of safety accidents. Moreover, the high temperature of the heating furnace is not acceptable for general materials, and the general temperature is above 200 degrees Celsius.
