Metallurgical plasma melting process

摘要

A metallurgical plasma melting process wherein a plasma burner and a separate start-up burner disposed alongside same in the same port have their axes intersecting in the furnace at an acute angle. Only the start-up burner is operated initially to form a crater in material in the furnace. Thereafter the plasma burner is ignited and the start-up burner is turned off when the plasma burner is operating at full efficiency.
