Abstract

METODO PARA PONER EN FUNCIONAMIENTO UN HORNO CONTINUO DE TRATAMIENTO TERMICO DE METALES, EN PARTICULAR PARA TRATAMIENTOS DE RECODIDO, ESFEROIDIZACION, SINTERIZACION, BRONCESOLDADURA, MALEABILIZACION Y ENDURECIMIENTO.COMPREN DE LAS SIGUIENTES OPERACIONES: PRIMERA, SE HACE PASAR EL MATERIAL A TRATAR TERMICAMENTE A TRAVES DEL HORNO DESDE LA ENTRADA HASTA LA SALIDA; SEGUNDA, SE SUMINISTRA GAS REDUCTOR Y GAS NO REACTIVO A LA REGION DE TRATAMIENTO TERMICO, EXISTIENDO FLUJOS SUSTANCIALES DE GAS DESDE LA REGION DE TRATAMIENTO TERMICO, TANTO EN LA DIRECCION DE LA ENTRADA COMO EN LA DIRECCION DELA SALIDA; Y POR ULTIMO, CON OBJETO DE REDUCIR EL CAUDAL DE GAS A SUMINISTRAR, SIN AFECTAR ADVERSAMENTE AL TRATAMIENTO TERMICO, SE IMPIDE SUSTANCIALMENTE EL INGRESO DE AIRE EN EL HORNO A TRAVES DE SU ENTRADA Y DE SU SALIDA.
