Plasma Torch Heats Up Interest in the Cupola

General Motors Corp and Westinghouse have teamed up to develop a cleaner, more efficient plasma melting system at GM's Central Foundry Div.

A plasma arc torch, originally developed for the space program, has been harnessed to the venerable cupola melting furnace, successfully pairing a 200-year-old iron melting process to a space-age technology. It happened this summer when General Motors Corp's Defiance, OH, Central Foundry Div formally accepted for production a cupola melting system that uses six electrically-powered plasma ...
