METHOD FOR CONTINUOUSLY CASTING GRAIN ORIENTED ELECTRICAL STEEL SLAB

PROBLEM TO BE SOLVED: To efficiently heat and roll a slab by cooling the overall slab width or the overall width except specific size ranges from the edge parts in the width direction by water spraying while the solidified shell thickness at the one side of long sides reaches at least a specific % o...

Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently heat and roll a slab by cooling the overall slab width or the overall width except specific size ranges from the edge parts in the width direction by water spraying while the solidified shell thickness at the one side of long sides reaches at least a specific % of the slab thickness after the slab is taken out from a mold. SOLUTION: When the solidified shell thickness at the one side reaches at least 25% of the slab thickness, non-water-spraying range is defined as
