Title:
CONTINUOUS CASTING METHOD FOR STEEL
Document Type and Number:
WIPO Patent Application WO/1996/002342
Kind Code:
A1
Abstract:
In order to control a jet current of molten steel, which is supplied to the interior of a casting mold for continuous casting through an immersed nozzle by applying a magnetostatic field between opposed side walls of the casting mold, according to the present invention, the molten steel is supplied to the interior of the casting mold at a throughput of not less than 6 t/min., and a magnetostatic field at a flux density of at least 0.5 T and a magnetostatic field at a flux density of not less than 0.5 T are applied at once to a meniscus portion of the casting mold and a lower portion of the jet current of the molten steel ejected from a discharge port of the immersed nozzle respectively, whereby an ingot piece the qualities of both the inner and outer portions of which are excellent is obtained.
