Numerical Simulation of In-mold Electromagnetic Stirring on Slide Gate Caused Bias Flow and Solidification in Slab Continuous Casting

A mathematical model coupled with electromagnetic field, flow, heat transfer and solidification has been developed to simulate the bias flow caused by slide gate under different slide-gate opening rates, EMS currents and casting speeds. Through comparing the magnetic flux density and flow field with measured results, the reliability of mathematical model is proved. The symmetric index, variance of solidified shell thickness have been introduced...
