Methods of using tires and scrap rubber in the manufacture and melting of steel and other metals
A method of using scrap rubber and other scrap materials, such as tires or parts or pieces of tires, to manufacture or melt steel and other metals in a furnace is disclosed. The scrap rubber may be used as a carbon source for the manufacture of steel and other metals, and may be used as an energy source to melt the scrap metal used to make the steel and other metals. The net benefit of this method includes reducing the amount of scrap rubber, such as tires, to be sent to a waste disposal facility or landfill, thereby improving the environment. In addition, by increasing the use of scrap rubber as a source of energy for steel or metal production, less energy is required from other sources.
1. A method of manufacturing steel and other metals or metal alloys comprising the steps of:
applying a quantity of metal into a furnace;
applying energy to the quantity of metal in the furnace to commence the melting of the metal; and
applying a quantity of an energy source to the melting metal in the furnace, wherein the quantity of an energy source does not include added metal,
wherein the quantity of an energy source is used to melt the metal and is selected from the group consisting of whole tires, tire pieces, tire parts, tire sections, tire bales, tire powder, tire particles, tire chunks, waste hoses, carbon-based rubber materials, rubber pieces, rubber parts, rubber sections, rubber powder, rubber particles, rubber chunks, carbon-based waste materials and carbon-based scrap materials.
2. A method of manufacturing steel and other metals or metal alloys comprising the steps of:
applying a quantity of metal into a furnace;
applying energy to the quantity of metal in the furnace to commence the melting of the metal;
transferring the melted metal in a ladle; and
applying a quantity of an energy source to the ladle to further melt the metal or provide a source of carbon, wherein the quantity of an energy source is selected from the group consisting of whole tires, tire pieces, tire parts, tire sections, tire bales, tire powder, tire particles, tire chunks, waste hoses, carbon-based rubber materials, rubber pieces, rubber parts, rubber sections, rubber powder, rubber particles, rubber chunks, carbon-based waste materials, carbon-based pieces, and carbon-based scrap materials.

12. The method of claim 10 wherein the step of applying coal or coke is performed prior to the step of applying the quantity of an energy source.
13. The method of claim 10 wherein the step of applying coal or coke is performed after the step of applying the quantity of an energy source.
14. A method of manufacturing steel and other metals or metal alloys comprising the steps of:
applying a quantity of metal into a furnace; and
separating a quantity of an energy source from a quantity of scrap metal or scrap steel, and
applying the quantity of an energy source to the furnace to further melt the metal or provide a source of carbon, wherein the quantity of an energy source is selected from the group consisting of whole tires, tire pieces, tire parts, tire sections, tire bales, tire powder, tire particles, tire chunks, waste hoses, carbon-based rubber materials, rubber pieces, rubber parts, rubber sections, rubber powder, rubber particles, rubber chunks, carbon-based waste materials, carbon-based pieces, and carbon-based scrap materials.
15. The method of claim 14 wherein the step of applying the quantity of metal and the step of applying the quantity of an energy source are performed at the same time.
16. The method of claim 15 wherein the step of applying the quantity of metal is performed prior to the step of applying the quantity of an energy source.
