| Abstract: | The materials employed to manufacture the roller shell for rapidly casting-rolling slabs in electric-magnetic field are required to possess not only high heat conductivity, high load-bearing capacity and high fatigue resistance, but also adequate magnetic-field controlling capacity, so as to ensure a sufficient magnetic intensity in the casting-rolling zone, which is needed to refine the grains and improve the microstructure and properties of the produced slabs. This article describes the influence of the roller-shell materials on the magnetic intensity in the casting-rolling zone, based on skin effect, eddy current effect, magnetic field attenuation and shielding effect occurring in the magnetic field. |
