Abstract
A process for melting scrap metal for producing steel which includes the steps of combining a quantity of scrap metal containing steel and at least about 0.25 percent by weight of 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.
Claims16
A process for melting steel scrap for producing steel in a furnace comprising:
- providing a container adjacent to the furnace, wherein the container is a rotary kiln;
- providing a quantity of scrap rubber into the container;
- providing at least one burner to ignite the quantity of scrap rubber in the container to convert the quantity of scrap rubber into combustible liquids and gasses;
- separating metal residue from the liquids and gasses;
- and
- feeding the converted scrap rubber into the furnace to add additional heat for melting the metal.
A process for separating metal from scrap tires, wherein the scrap tires may be used in a fuel burning system, the process comprising:
- providing a container adjacent to the fuel burning system, wherein the container is a rotary kiln;
- providing a quantity of scrap tires into the container, the scrap tires including metal wires formed therein;
- providing at least one burner to ignite the quantity of scrap tires in the container to convert the quantity of scrap tires into a combustible fluid and to separate the metal wires from the scrap tires;
- and
- feeding the converted scrap tires into the fuel burning system.
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 burner to ignite the scrap rubber in the scrap tire container such that heat is produced and to convert the quantity of scrap tires into a combustible fluid;
- utilizing and transferring heat generated by the ignited scrap rubber in the scrap tire container to the metal in a furnace to heat the metal in the furnace to reduce the amount of external energy required to be applied to the furnace for melting of the 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.
