Effects of Steel Teeming in New Slide Gate System with Electromagnetic Induction

 Steel teeming time is a very important parameter in the new slide gate system with electromagnetic induction (called electromagnetic steel teeming system), and how to shorten this time is a key to realize application of the new system in continuous casting. The effects of power parameters, coil position, nozzle material and other factors on the steel teeming time were investigated by a self-designed electromagnetic steel teeming system in detail. The experimental results show that the relationship between power and steel teeming time is nonlinear. The coil position has great influence on steel teeming time. And the upper nozzle with high permeability can reduce the teeming time. In addition, the steel teeming time becomes minimum when the size of the spherical cast iron particles is 2.0 mm. This research can provide technical references for the industrial application of the new electromagnetic steel teeming system.
