摘要：A method of melting materials at power densities in excess of 25 KW/ft. sup.2 ofarea within the metal shell of a melting vessel which method consists essentially ofcontinuously feeding the material to be melted to a plasma arc furnace which is equippedwith at least two transferred arc plasma electrodes and with means to rotate at least theportion of the furnace containing the material to be melted, melting the said feedstockmaterial using the at least two transferred arc plasma electrodes whilst rotating at leastthe rotatable portion of the furnace containing the material to be melted andcontinuously discharging the material which has been melted from the furnace.

Apparatus for melting materials under power densities of greater than 25 KW/ft.sup.2is also disclosed.
