Industrial Normalizing Furnace

Normalizing Process

During the normalizing process metal is heated to a temperature and then held at that temperature for a specified amount of time. After the metal is finished with the heating process, it is air cooled at room temperature. The resulting microstructure has increased strength and hardness but lower ductility because it is a mixture of ferrite and cementite. Normalizing is commonly performed in an industrial box furnace, pit or top load furnace, or integral quench furnace.
