| Abstract Scope |
Electromagnetic stirring has become an essential technique to improve billet quality during continuous casting process. Compared with the conventional electromagnetic stirring (EMS), permanent magnet stirring (PMS) based on sintered NdFeB material owns the great advantages of simple structure, high magnetic flux densities and low power consumption. In this work, the characteristics differences between electromagnetic stirring and permanent magnet stirring are explained, and the present application of permanent magnet stirring is also introduced in square billet continuous casting. Industrial trials suggest that mold PMS can decrease the hole defects on the surface and improve the central porosity and carbon segregation of the billet. Final permanent magnet stirring is adopted at solidification end of the high carbon steel continuous casting. Experimental results reveal that with the increase in the rotation speed of PMS, the central carbon segregation index of the billet decreases obviously. |
