Methods of using tires and scrap rubber in the manufacture and melting of steel and other metals

A method of increasing the consumption of tires used in the manufacture of steel comprising the steps of:

• depositing a quantity of scrap metal into an electric arc furnace;
• and
• depositing a quantity of tires into the furnace separate from the quantity of scrap metal and at a controlled rate;
• thereby causing combustion of the quantity of tires to add additional heat for melting the scrap metal, and whereby the quantity of tires provide a carbon source for the steel.

A method of improving the preheating of scrap metal in a shaft or conveyor fed furnace comprising the steps of:

• applying a quantity of scrap metal into a furnace;
• applying energy to the quantity of scrap metal in the furnace to commence the melting of the scrap metal and the forming of a slag of material;
• and
• applying a quantity of tires to the slag of material in the furnace,
• whereby the quantity of tires add additional heat for the melting of the scrap metal.

A method of using tires in the manufacture of steel comprising the steps of:

• applying a quantity of scrap metal into an electric arc furnace;
• applying energy to the quantity of scrap metal in the furnace to commence the melting of the scrap metal and the forming of a slag of material;
• and
• applying a quantity of tires and a quantity of coal to the slag of material in the furnace,
• whereby the quantity of tires add additional heat for the melting of the scrap metal.

A method of using tires in the manufacture of steel comprising the steps of:

• applying a quantity of scrap metal into an electric arc furnace;
• applying energy to the quantity of scrap metal in the furnace to commence the melting of the scrap metal and the forming of a slag of material, the slag releasing carbon monoxide gas;
• and
• applying a quantity of tires to the slag of material in the furnace,
• whereby the quantity of tires convert the carbon monoxide gas to carbon dioxide gas.

A method of improving the preheating of scrap metal in a shaft or conveyor fed furnace comprising the steps of:

• applying a quantity of tires into a furnace;
• applying energy to the quantity of tires in the furnace to commence the combustion of the tires, whereby heat from the combustion preheats a quantity of scrap metal;
• and
• applying the quantity of scrap metal to the furnace.
