A forging furnace is a type of furnace used in the forging process to heat metal to a malleable temperature for shaping and forming. It typically uses a fuel source, such as natural gas or coal, and can reach temperatures upwards of 2,500 deg F. This forging furnace may be designed for batch or continuous operation, and can vary in size and shape depending on the specific application. Heat is transferred to the metal through conduction, radiation, and convection, and the metal is then shaped using various forging techniques.
