Abstract

PARA LA TECNICA DE LA PULVIMETALURGIA ES IMPORTANTE LA PREPARACION DE UNOS POLVOS DE METAL ADECUADOS. HASTA AHORA LOS POLVOS DE METAL, EN PARTICULAR LOS METALES DE ELEVADO PUNTO DE FUSION, SE FABRICABAN SIGUIENDO UNOS PROCEDIMIENTOS EN LOS QUE SE INVERTIA MUCHO TIEMPO, RESULTANDO, POR TANTO, MUY COSTOSOS, MEDIANTE LA REDUCCION DE LOS COMPUESTOS METALICOS, POR EJEMPLO, MEDIANTE LA REDUCCION DE LOS COMPUESTOS METALICOS SOLIDOS EN POLVO DE METAL EN UN HORNO DE FLUIDIZACION U HORNO EMPUJADOR. SEGUN LA PRESENTE INVENCION, LA REDUCCION DE LOS COMPUESTOS METALICOS PULVERULENTOS SE REALIZA MANTENIENDO LA FASE SOLIDA, COMO UN PROCESO CONTINUO, HACIENDO QUE LAS PARTICULAS PASEN SIGUIENDO UNA TRAYECTORIA PREDETERMINADA POR UNA CAMARA DE REACCION. LA DURACION DEL PROCEDIMIENTO PARA EL CICLO DEL PROCESO ES POR TERMINO MEDIO DE 0,4 A 60 SEGUNDOS. CON ELLO LOS PROCESOS SE COMPLETAN EN UN 90 % COMO MINIMO.
