  • Method and plant for fully continuous production of steel strip from ore
    Patent number: 4664701
    Abstract: The specification discloses fully continuous production of steel strip from ore. Ore is continuously charged in particulate form to a reactor where it is adhered to hot metal in a continuous flash smelting process. The hot metal is continuously refined, is continuously clarified by bubbling an inert gas through it, is continuously alloyed, and is then continuously degassed. The degassed metal is then continuously cast and continuously rolled to steel strip.
