Abstract
A method for producing a ferrous alloy may include: melting a ferrous metal charge in a metallurgical furnace to obtain a mass of molten metal; and feeding into the metallurgical furnace, before, during, and/or after the melting of the ferrous metal charge, at least one granular composite material including: greater than or equal to 50% and less than or equal to 97% by weight of a polymeric component including polyethylene; and greater than or equal to 3% and less than or equal to 50% by weight of metallic aluminum. The percentages by weight refer to a total weight of the polymeric component including polyethylene and the metallic aluminum.

A method for producing a ferrous alloy, the method comprising:
- melting a ferrous metal charge in a metallurgical furnace to obtain a mass of molten metal;
- and
- feeding into the metallurgical furnace, before, during, and/or after the melting of the ferrous metal charge, at least one granular composite material comprising:
- greater than or equal to 50% and less than or equal to 97% by weight of a polymeric component comprising polyethylene;
- and
- greater than or equal to 3% and less than or equal to 50% by weight of metallic aluminum;
- wherein the percentages by weight refer to a total weight of the polymeric component comprising polyethylene and the metallic aluminum.
A method of employing at least one granular composite material that comprises greater than or equal to 50% and less than or equal to 97% by weight of a polymeric component comprising polyethylene, and greater than or equal to 3% and less than or equal to 50% by weight of metallic aluminum, wherein the percentages by weight refer to a total weight of the polymeric component comprising polyethylene and the metallic aluminum in a ferrous alloy production process in a metallurgical furnace, the method comprising:
- using the at least one granular composite material as one or more of fuel, reducing agent, foaming slag-forming agent, deoxydizing agent, and recarburizing agent.
