In the present study, a composite billet that consisted of a GCr15 steel as the composite layer and a 45 carbon steel as the roll core was produced by a new electroslag cladding method. Microstructure evolution at different radial regions of the roll core during the production process were discussed and the microstructure, elements diffusion, microhardness, tensile strength of the bonded regions were measured. The results illustrate that the bimetal materials achieves an excellent metallurgical bonding by the new method and the bonding interface isn't the weakest region during the loading process. Affected by the heat transfer from the high temperature slag pool, a high temperature austenitizing process and an obvious elements migration and diffusion phenomenon occur at the heat affected zone of the roll core which leads to a gradual change of the microhardness from the composite layer to the roll core.
