Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA EL TRATAMIENTO TERMICO DE PIEZAS DE TRABAJO METALICAS EN UN HORNO CONTINUO CALENTADO POR GAS, BAJO LA INFLUENCIA DE ATMOSFERA GASIFICADA, FORMADA ESENCIALMENTE POR NITROGENO, HIDROGENO Y MONOXIDO DE CARBONO. CON EL FIN DE RENTABILIZAR ESTE PROCEDIMIENTO MEDIANTE EL AHORRO DE GAS, SE PROPONE QUE LA ATMOSFERA GASIFICADA A BASE DE UN GAS DE TRATAMIENTO, CONTENIENDO NITROGENO, HIDROGENO Y MONOXIDO DE CARBONO, SEA APORTADO AL HORNO CONTINUO EN EL AMBITO DE SU ZONA CALIENTE, Y QUE ANTES DE SU INMEDIATA ENTRADA EN EL HORNO CONTINUO, SE GENERE POR TRANSFORMACION CATALITICA UN GAS, CONTENIENDO HIDROCARBUROS Y AIRE, Y PARA FORMAR NITROGENO, QUE ES APORTADO AL HORNO CONTINUO POR AMBAS PARTES DEL PUNTO DE ALIMENTACION PARA EL GAS DE TRATAMIENTO, ENTRE LA ENTRADA AL HORNO Y ZONA CALIENTE, ASI COMO ENTRE LA ZONA CALIENTE Y SALIDA DEL HORNO.
