Abstract

OXIGENO O UN GAS MIXTO CONTENIENDO OXIGENO O UNA LLAMA QUIMICA, PRODUCIDA POR UNA MEZCLA DE GAS DE COMBUSTION Y UN GAS QUE AYUDA A LA COMBUSTION, CONTENIENDO OXIGENO, SE INSUFLA CONTRA LA SUPERFICIE DE HIERRO FUNDIDO PARA OCASIONAR EMISION DE RADIACION. LAS RADIACIONES SE DIVIDEN EN LOS COMPONENTES DE DIFERENTES LONGITUDES DE ONDA Y LOS ESPECTROS DE EMISION RESULTANTES SE MIDEN PARA DETERMINAR LA COMPOSICION DEL HIERRO FUNDIDO.OXYGEN OR A MIXED GAS CONTAINING OXYGEN OR A CHEMICAL FLAME, PRODUCED BY A MIXTURE OF COMBUSTION GAS AND GAS THAT HELPS COMBUSTION, CONTAINING OXYGEN, IS INSULATED AGAINST CAST IRON SURFACE FOR OCAS RADIATIONS ARE DIVIDED INTO THE COMPONENTS OF DIFFERENT WAVE LENGTHS AND THE RESULTING EMISSION SPECTRUMS ARE MEASURED TO DETERMINE THE COMPOSITION OF CAST IRON.
