Refining is a process that consists of quenching and subsequent casting of a component at higher temperatures, as required and according to the selected material type, in the temperature range of about 400°C to 650°C. It results in an increase in mechanical properties (e.g. strength, yield, elongation and contraction) while maintaining the high toughness of the material. Examples include shafts and other power components of machinery and transport equipment, fasteners, locks, and the like.
The quenching process is performed with semiautomatic multipurpose furnaces IPSEN with a controlled atmosphere of carbon potential or in salt baths.
The process is carried out in air ovens, in protected atmosphere furnaces or in salt baths.
