Abstract

ON AFFINE LA FONTE OU LE FER BRUT EN FUSION POUR FORMER UN BAIN D'ACIER EN FUSION A PLUS FAIBLE TENEUR EN CARBONE QUE LA TENEUR FINALE DESIREE DANS L'ACIER, PUIS ON CEMENTE LE BAIN D'ACIER EN DISSOLVANT DANS CELUI-CI DU CARBURE DE FER EN UNE QUANTITE PERMETTANT D'OBTENIR LA TENEUR FINALE DESIREE EN CARBONE.THE CAST IRON OR CRUDE FUSION IS REFINED TO FORM A BATH OF FUSION STEEL WITH LOWER CARBON CONTENT THAN THE DESIRED FINAL CONTENT IN THE STEEL, THEN THE STEEL BATH IS CEMENTED BY DISSOLVING IN THE STEEL. IRON CARBIDE IN AN QUANTITY TO OBTAIN THE DESIRED FINAL CARBON CONTENT.
