Chemical Engineering - Furnace Technology - Discussion

An annealing furnace is a piece of equipment used to heat a material at very high temperatures, to change its hardness and strength properties. Annealing is commonly associated with the manufacture of steel, to relieve internal stresses that may lead to failure in service and to produce a more uniform, or homogeneous, internal structure. This process is also commonly used with various metals, glass, and other materials to make them less brittle and more workable.
