Abstract
A process for melting scrap metal for producing steel which includes the steps of combining a quantity of scrap metal and scrap rubber in an electric arc furnace. Energy is then applied to the quantity of steel and scrap rubber in the furnace to start the combustion of the scrap rubber to add additional heat for melting the scrap metal containing steel.
Claims10
A process for melting metal in a vessel comprising:
- providing a container adjacent to the vessel, wherein the container is a rotary kiln;
- providing a quantity of scrap rubber into the container;
- providing at least one burner to heat the quantity of scrap rubber in the container to convert the quantity of scrap rubber into combustible liquids, gasses and solids;
- separating metal residue from the liquids, gasses and solids;
- providing the converted scrap rubber into the vessel containing metal;
- and
- melting the metal contained in the vessel using in part the converted scrap rubber.

A process for melting steel scrap for producing steel in a furnace comprising:
- providing a scrap tire ignition container positioned adjacent the furnace and in heat and material transfer connection therewith, the scrap tire container including a quantity of scrap rubber, wherein the scrap tire container is a rotary kiln;
- providing at least one heat source to heat the scrap rubber in the scrap tire container to convert the quantity of scrap tires into combustible fluids;
- providing a quantity of scrap metal in the furnace;
- utilizing and transferring heat generated in the scrap tire container to the scrap metal in the furnace to heat the scrap metal in the furnace to reduce the amount of external energy required to be applied to the furnace for melting of the scrap metal and to thereby increase the efficiency of the furnace;
- separating metal residue from the combustible fluid;
- and
- feeding the combustible fluid into the furnace to aid in melting the scrap steel-metal in the furnace.
