Abstract
The present invention provides a previously unattainable compact and high thrust electromagnetic stirrer coil, that is, an electromagnetic stirrer coil for stirring molten steel in a mold by electromagnetic force, in which electromagnetic stirrer coil a space factor of the yoke sectional area (−) with respect to an inside area in a horizontal cross-section of said electromagnetic stirrer coil is 0.5 to 0.9 and a yoke width B is 100 mm to 300 mm. Preferably, a magnetomotive force F of said electromagnetic stirrer coil divided by the yoke width B, that is, a value of F/B, is 800 kAT/m 2 or more.
Claims
exact text as granted — not AI-modified1 . An electromagnetic stirrer coil for stirring molten steel in a mold by electromagnetic force, said electromagnetic stirrer coil characterized in that a space factor of the yoke sectional area (−) with respect to an inside area in a horizontal cross-section of said electromagnetic stirrer coil is 0.5 or more and a yoke width B is 100 mm to 300 mm.
2 . An electromagnetic stirrer coil as set forth in claim 1 , characterized in that a magnetomotive force F of said electromagnetic stirrer coil divided by the yoke width B, that is, a value of F/B, is 800 kAT/m or more.Cited by (0)
