摘要

P METHOD FOR HEATING A CONTINUOUS CASTING STEEL SLAB FOR THE PRODUCTION OF ORIENTATED GRAIN SILICON STEEL SHEETS HAVING A HIGH DENSITY OF MAGNETIC FLUX, CHARACTERIZED IN WHICH IT CONSISTS OF MAINTAINING, IN A HEATING OVEN BRAME, A CONTINUOUS CASTING SLAB CONTAINING NO MORE THAN 0.085 CARBON, 2.0-4.0 SILICON, NO MORE THAN 0.15 MANGANESE, AND 0.010-0.065 SOLUBLE ALUMINUM, A A TEMPERATURE THAT IS NOT LESS THAN 1300C, FOR A DURATION THAT IS NOT LESS THAN 30 MINUTES, THE TEMPERATURE OF THE SLAB, AT THE END OF THE SAME PERIOD, IS NOT LESS THAN 1330C. /P
