Microstructural formation and development of a semisolid casting technique were evaluated for magnesium alloy AZ31B sheet by using an inclined cooling plate to obtain refined and globular primary α crystals. This research investigates the influence of the tundish position and the roll speed on strip processing. It was found that placing the tundish closer to the roll gap increased the strip thickness and smoothness of the sample surface. Increasing the rotating speed of the roll results in an uneven, unstable and oxidized molten surface at the upper side of the sample. 2 mm and 3 mm thick samples were produced by optimizing the solidification conditions.
