Abstract

PROCEDE DE FABRICATION PAR COULEE CONTINUE DE BRAMES DESTINEES A L'ELABORATION DE TOLES ET BANDES D'ACIER A GRAINS ORIENTES A USAGE ELECTRIQUE, CARACTERISE EN CE QU'IL CONSISTE A: -TRANSFERER L'ACIER FONDU, PREPARE PAR COULEE CONTINUE ET NE CONTENANT PAS PLUS DE 4,0 DE SILICIUM ET DE 0,01 A 0,08 D'ALUMINIUM ET DE 0,01 A 0,06 DE SOUFRE, DANS UNE POCHE OU DANS UN AUTRE RECEPTACLE DE COULEE; REPARTIR UN LAITIER CONSTITUE ESSENTIELLEMENT DE SIO, DE CAO ET DE ALO, SUR LA SURFACE DE L'ACIER LIQUIDE EN REGLANT LE RAPPORT ALOSIO DE CE LAITIER A UNE VALEUR QUI N'EST PAS INFERIEURE A 0,25 ET; -EFFECTUER LA COULEE CONTINUE DE L'ACIER FONDU.CONTINUOUS CASTING MANUFACTURING PROCESS OF SLABS INTENDED FOR THE PREPARATION OF ORIENTED GRAIN STEEL SHEETS AND STRIPS FOR ELECTRICAL USE, CHARACTERIZED IN THAT IT CONSISTS OF: -TRANSFERING THE MELT STEEL, PREPARED BY CONTINUOUS CASTING AND NOT CONTAINING NOT MORE THAN 4.0 SILICON AND 0.01 TO 0.08 ALUMINUM AND 0.01 TO 0.06 SULFUR, IN A POCKET OR OTHER CASTING RECEPTACLE; DISTRIBUTE A MILK CONSTITUTE ESSENTIALLY OF WIS, CAD AND ALO, ON THE SURFACE OF THE LIQUID STEEL BY SETTING THE ALOSIO RATIO OF THIS MILK TO A VALUE WHICH IS NOT LESS THAN 0.25 ET; - PERFORM THE CONTINUOUS CASTING OF MELT STEEL.
