Abstract
SE REFIERE LA INVENCION A UN PROCEDIMIENTO PARA FABRICAR ACERO A PARTIR DE CHATARRA EN UN RECIPIENTE DE AFINO EN EL QUE SE INTRODUCE UNA LANZA DE SOPLADO BAJO LA SUPERFICIE DEL BAÑO DE ACERO Y EN LA QUE SE DISPONE DE UN DISPOSITIVO DE SOPLADO EN EL QUE SE TIENE UN COMBUSTIBLE SOLIDO QUE CONTIENE CARBONO Y GAS ENRIQUECIDO EN OXIGENO QUE SE INTRODUCEN COMO PARTICIPANTES EN LA REACCION. COMO APORTE DE CALOR A LA CHATARRA Y AL RECIPIENTE DE AFINO SE UTILIZAN LOS MISMOS GASES DE REACCION Y LOS PRODUCTOS DE REACCION QUE SE DESPRENDEN EN FORMA GASEOSA SE QUEMAN AL FINAL CON AIRE PRECALENTADO.
