Abstract

POUR REVETIR UNIFORMEMENT D'UNE MATIERE 8 DE PROTECTION CONTRE L'USURE LE GARNISSAGE REFRACTAIRE 1 D'UN FOUR DE FUSION METALLURGIQUE 2, APRES AVOIR FAIT COULER LE METAL FONDU, ON RETIENT DANS LE FOUR 2 LE LAITIER DE PROCESSUS 4 QUI EST FONDU ET LIQUIDE ET QUI S'EST FORME PENDANT LE PROCESSUS METALLURGIQUE, ON INTRODUIT DANS CE LAITIER 4 DES SUBSTANCES 6 CAPABLES DE PROVOQUER UN DEGAGEMENT DE GAZ, POUR FAIRE MOUSSER LE LAITIER 4 AFIN QU'IL MOUILLE LE GARNISSAGE 1 DU FOUR DE FUSION 2 ET POUR QU'ENSUITE, LE LAITIER ADHERE AU GARNISSAGE 1 EN SE SOLIDIFIANT, ET ENSUITE, ON ELIMINE DU FOUR 2 LE LAITIER QUI EST RESTE LIQUIDE 4.TO COVER UNIFORMLY WITH A MATERIAL 8 PROTECTING AGAINST WEAR THE REFRACTORY LINING 1 OF A METALLURGIC FUSION OVEN 2, AFTER HAVING FLOWED THE MELT METAL, THE MILK FROM PROCESS 4 WHICH IS MELTED AND IS RETAINED IN OVEN 2 IN OVEN 2. LIQUID AND WHICH FORMED DURING THE METALLURGIC PROCESS, WE INTRODUCE 4 OF THE SUBSTANCES 6 IN THIS MILK CAPABLE OF GENERATING GAS, TO LET MILK 4 SO THAT IT WET THE LINING 1 OF THE FUSION OVEN 2 AND FOR THEN, THE MILK ADHESES TO THE PADDING 1 BY SOLIDIFYING, AND THEN ELIMINATES FROM THE OVEN 2 THE MILK WHICH IS REMAINING LIQUID 4.
