Title:
CONTINUOUS CASTING METHOD, CAST SLAB, AND CONTINUOUS CASTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/172142
Kind Code:
A1
Abstract:
In this continuous casting method, an unsolidified portion in a slab conveyed from a mold is stirred by a first electromagnetic stirring device and a second electromagnetic stirring device disposed, with respect to the conveyance direction of the slab, downstream of the first electromagnetic stirring device, and thereafter the slab is reduced by a reduction roller. The first electromagnetic stirring device alternately applies, to the slab, a one-direction electromagnetic force that causes the unsolidified portion to flow in a one lateral direction of the slab at a flow rate of at least 5 cm/s and another-direction electromagnetic force that causes the unsolidified portion to flow in another lateral direction of the slab at a flow rate of at least 5 cm/s.
