Abstract:
1. A continuous casting method of steel in which an electromagnetic stirrer is installed upstream, in the casting direction, of a reduction rolling position of a slab, and in which a slab with a liquid core is reduced in thickness, comprising: selectively imparting, by means of the electromagnetic stirrer, a stirring flow which causes molten steel to flow from both minor sides of slab toward the width-wise center of slab and collide with each other in the vicinity of the width-wise center, and a stirring flow which causes molten steel to flow from one minor side of slab toward the other minor side thereof while reversing the flowing direction at a predetermined time interval, wherein at least one electromagnetic stirrer is installed at a distance of less than 9 m upstream, in the casting direction, of the reduction rolling position of the slab.
