Abstract

TRATAMIENTO TERMICO A PIEZAS DE HIERRO. CONSTA DE LAS SIGUIENTES OPERACIONES: 1. FORMAR UNA MEZCLA DE TRATAMIENTO GASEOSO PARA OBTENER UNA COMPOSICION ENDOTERMICA. 2. INTRODUCIR LA MEZCLA EN EL HORNO CON UN CAUDAL DE CINCO A 20 LITROS POR MINUTO, TENIENDO DICHO HORNO UN VOLUMEN PROXIMO A 225-337 1./MINUTO. 3. QUEMAR LA MEZCLA GASEOSA EN EL HORNO, CONTROLANDOSE EL CAUDAL DE LOS GASES QUEMADOS PARA OBTENER UN TIEMPO DE RESISTENCIA MEDIO EN EL HORNO PROPORCIONAL A LA TEMPERATURA DE LA ATOMOSFERA, QUE VARIA ENTRE 69 MINUTOS A 800 GC Y 17 MINUTOS A 1.000 GC. EL GAS EMILLADO ES PROPANO, MEZCLANDOSE CON AIRE EN UNA PROPORCION DE AIRE-GAS DE 6,0 A 8,0. OPCIONALMENTE SE PUEDE EMPLEAR METANO EN UNA PROPORCION AIRE-GAS DE 1,6-2,4.
