A continuously casting machine is provided with structure for agitating under action of magnetic force the molten steel in a slab drawn from a mold. The agitating device comprises permanent magnet groups arranged on both surfaces of the longitudinal sides of the slab and extending from the part directly below the mold to the completely solidified part of the slab. Direct current is passed to the molten steel in the slab, thereby providing the agitating force under the mutual action of a stationary magnetic field and direct current to the molten steel.

Continuously casting machine

In a continuous casting machine, displacement-electricity converters are mounted slidably longitudinally on a long guide having the same radius of curvature as that of the roller apron of the casting machine. The long guide is inserted between the rolls of the roller apron. The displacement of the roller apron with respect to each reference position is measured with the displacement-electricity converters.
