Plasma Hearth Melting

Plasma Hearth Melting

Plasma Hearth Melting is a process used to melt titanium alloys and other metals into ingots for refining or re-melting of scrap.

Some advantages over other melting processes is chemistry control and refining capabilities. Both single melt and conventional PAM + VAR melting are industry approved processes.

Laboratory PAM button melting is a single plasma torch process used to melt Titanium alloys for chemical and mechanical properties.  The buttons are melted several times using an inert gas on each side to ensure alloy homogenization.  Subsequent buttons are typically hot or cold rolled to obtain enough reduction for grain size, chemistry and mechanical property evaluations.

Advantages:

PAM laboratory scale melting can produce very small to medium sized ingots for full scale production alloy development.

•  Reduces full scale materials and labor expenses
•  Reduces time to investigate new alloys and processing
