Zusammenfassung:	PROCEDE DE GARNISSAGE DE FOURS ELECTRIQUES D'ELABORATION D'ACIER.UNE MATIERE EST CONSTITUEE PAR: 100 PARTIES EN POIDS DE MAGNESIE; 0,5 A 5,0 PARTIES EN POIDS D'OXYDE DE CHROME VERT; 0,5 A 3,0 PARTIES EN POIDS D'ARGILE; 0,5 A 3,0 PARTIES EN POIDS DE METAPHOSPHATE OU DE POLYPHOSPHATE DE METAL ALCALIN; 0,2 A 1,5 PARTIES EN POIDS DE BISULFATE DE METAL ALCALIN; 8 A 10 PARTIES EN POIDS D'EAU EST APPLIQUEE EN 9 PAR PROJECTION OU ETALEMENT SUR LES SURFACES FROIDES, PROPRES DU REVETEMENT D'USURE 5 DANS LES ZONES SOUMISES A L'USURE 7 ET EST CONSOLIDEE PAR LA MISE EN MARCHE IMMEDIATEMENT APRES DU FOUR ELECTRIQUE. Method of lining a steel-making furnace which comprises lining the bottom area of the furnace with bricks to form a first lining, lining at least a portion of the wall area of the furnace with bricks and/or a water cooling box to form a second lining, lining the first lining and a lower portion of the second lining with a first refractory material, applying a second refractory material to an upper portion of the second lining above the lower portion before heating the furnace, and then heating the second refractory material to cause hardening thereof. The second refractory material comprises magnesium oxide, green chromium oxide, clay, a phosphate, a bisulfate and water. The use of this composition for the second refractory material results in a substantial increase in the durability of the furnace lining.
