Abstract

A metal alloy, such as steel, is manufactured in an electric arc furnace system equipped with at least one sensor, at least one a controller including a logic program and a variable valve in fluid communication with the furnace and a material source. The nature and quality of the slag formed over a molten metal during manufacture of steel is dynamically controlled by continuously adjusting the addition of one or more material to the arc furnace through the variable valve.
