<p>A continuous process is provided for rapid melting of a variety of virgin an d recycled ferrous and non-ferrous metals. This is accomplished by distributin g the introduction of the unmelted charge materials and hence the melting heat requirements along an elongate gas-solid-liquid reaction zone within a rotar y furnace, according to the distribution of heat available to effect melting. In the case of fine-sized metal charge materials, fluxes and additive reagents, this charge distribution is implemented by traversing of the nozzle jet, as directed to penetrate into the metal and slag bath from a solids injection lance, successively backwards and forwards and, in the case of coarse-sized materials, by traversing of the dischage from an oscillating conveyor.</SDOA B></p> |
