An annealing furnace is an industrial furnace used for heat treating metals. It involves heating the metal to a high temperature, holding it at that temperature, and then allowing it to cool slowly.
This process, known as annealing, softens the metal for easier processing and eliminates residual stresses caused by manufacturing processes like cutting and pressing.
Annealing furnaces are used in various industries for treating metals such as steel, cast iron, stainless steel, and aluminum. They are essential for softening metals, removing internal stresses, and ensuring uniform quality. Annealing can also straighten warped metal plates and demagnetize metals with magnetic properties.
These furnaces are found in sectors including machinery and automobile manufacturing, shipbuilding, aerospace, and canning.
Annealing furnaces operate by heating metal materials using gas or electricity to temperatures above their transformation points. The duration and temperature of the heating and cooling phases are precisely controlled, allowing metals to acquire desired properties.
For example, steel is typically heated to around 1112 °F. The heat treatment alters the metal's properties by bonding it with other elements or changing its crystal structure.
Annealing furnaces vary in size and shape, including cylindrical, cube-like, and elongated rectangular designs. Some have double structures for insulation or separate chambers for heating and cooling. Advanced models can perform annealing in vacuum or nitrogen atmospheres.
Heat treatment aims to alter metal properties by adjusting temperature, duration, and cooling method. The main objectives include increasing hardness, tempering to achieve desired properties, and removing internal stresses caused during processing.
