摘要:
One or more electromagnetic stirring elements are mounted on arms and/or holders, extending from a carriage which runs on a stationary bed and in a direction transversely to the direction of casting. The stirring elements are either directly positioned in the direction of carriage movement or orthogonally thereto. Multiphase elements can be positioned from three different directions to circumscribe the casting.
摘要:
An electromagnetic stirring apparatus for stirring the liquid center core of a continuous casting. The casting is supported by and transported over guide rolls while a changing electromagnetic field is induced within the liquid casting core by induction coils positioned beneath the casting. Fingers of a stack of ferromagnetic plates form the cores of the induction coils and are positioned between the guide rolls and are close enough to the casting to induce a strong field therein.
摘要:
Effectiveness of internal cooling of the rollers in a withdrawal path for continuously cast ingots is determined by measuring the drop in surface temperature of the ingot when in engagement with the rollers. For this, a thermo element is affixed to the ingot's surface and its output is recorded or otherwise processed.
