Some typical processes that can be performed in the VCAP range include:
• Air melting from solid charge (option for vacuum melting)

• Controlled atmosphere melting from solid charge

• Alloy homogenization and chemistry adjustment

• Vacuum degassing (hydrogen and nitrogen removal)

• Reduction of low vapor pressure tramp elements (e.g. Pb, Cd, Bi, Zn)

• Deoxidation using combination of vacuum and C-O reaction

• Decarburization - Intensified C-O reaction at low pressure enabling excellent       decarburization for extra low carbon levels.

• Desulphurization

• Argon purging of metal with pourous plug

Some of the more important customer product advantages from VCAP operation are:
• Generally significant improvement of mechanical properties, such as yield strength, ductility, impact strength, fatigue and stress rupture elevated temperature properties.

• Improvement of technological characteristics, such as hot workability, weldability and machinability.

• Better microcleanliness due to strong carbon deoxidation and smaller residual inclusions.

• Significantly reduce scatter in product properties and characteristics, less rejections.
