Abstract

METODO Y SU CORRESPONDIENTE APARATO PARA FUNDIR CHATARRA DE HIERRO Y ACERO. METODO PARA FUNDIR CHATARRA DE HIERRO Y ACERO EN EL CUAL LA CHATARRA SE INTRODUCE A TRAVES DE UN HORNO DE CUBA A CONTRACORRIENTE RESPECTO A UN GAS REDUCTOR. EL GAS REDUCTOR SE FORMA HACIENDO PASAR AIRE A TRAVES DE UN GENERADOR DE PLASMA E INYECTANDO CARBON Y/O HIDROCARBUROS EN EL AIRE CALIENTE, DE TAL MANERA QUE LA RELACION (CO2 + H2O)/(CO2 + H2O + CO + H2) DEL GAS RESULTANTE, SEA INFERIOR A 0
