Induction coil system for variable width casting in semi-contact electromagnetic continuous casting of steel slabs

摘要

The present invention is directed to an induction coil system for variable width casting during semi-contact electromagnetic continuous casting of steel slabs, and includes a plurality of bar-shaped long-side coils installed on the long sides of a mold in a semi-contact electromagnetic continuous casting machine for steel slabs. And a plurality of bar-shaped short side coils provided at the short side of the mold, and a plurality of flexible coils connecting the long side coils and the short side coils, wherein each of the long side coils includes: Variation of the width of the short side part is because the two sides of the longitudinal direction has a ring that slides along the length direction, and these rings are integrally connected, and the integrally connected ring is connected to the short side through a connecting member. The length of the long side coil to which the current is applied is varied by bringing the movement along the long side coil of the ring. An induction coil system for variable width casting is disclosed.
