Continuous strip casting and direct rolling method are receiving attention as the integrated producing process to obtain wrought Magnesium alloys. In this research, AZ61 strip was cast from molten metal by twin-roll strip caster and it was rolled by "Structure-Control rolling process". The effects of casting conditions and rolling parameters on surface aspect and microstructure of the rolled sheet were investigated. Obtained results are as follows: (1) By using structure-control rolling with R.T. pass, microstructure of the mean grain size of 5μm was obtained. (2) By lowering starting rolling temperature, mean grain size and duplex grain size degree decreased and hardness increased. In addition, the deformation resistance decreased and the fracture strain increased.
