| Abstract: | In order to relieve or erase the defects of macro segregation, shrinkage porosity and inclusion in the thin slab by horizontal continuous casting, and to optimize the casting process and reach the results of the improved solidification structure and homogenized composition, the electromagnetic stirring technique could be applied to the liquid steel in the mould. A physical simulation experiment of electromagnetic stirring in horizontal continuous casting was conducted, in which the molten metal was displaced by mercury. The distribution of magnetic field and electric current in the mercury, the flow behavior and the velocity of the mercury, and the relations of stirring velocity of the mercury with the current were investigated. |
