Analysis of the effects of electromagnetic stirring on solidification structure of bearing steel
Abstract
In the current study, a 260 mm × 300 mm bloom mould was investigated, on which a method combining finite element and finite volume methods was applied to study the impacts of electromagnetic stirring on molten steel flow and heat transfer, and then t he solidification structure of steel was tested. The obtained simulation results pertaining to magnetic fields were consistent with the onsite measured data. For the 260 mm × 300 mm bloom continuous casting of bearing steel, the appropriate value of current intensity of electromagnetic stirring was found to be 300 A.
