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.

The heating furnace uses the high temperature flame and flue gas generated when the fuel burns in the furnace as the heat source to heat the medium flowing in the furnace tube to reach the specified process temperature.
