Casting of Ingots for Thixo-Forming Using a Downward Melt Drag Process
A downward melt drag single roll caster (DMDSRC) was devised to make ingots for thixo-forming. DMDSRC was assembled from a roll and a nozzle. Therefore, process was very simple. A copper roll surface was not coated by lubricant. However, the metal did not stick to roll and semi-solid slurry could be made continuously. Primary crystal became globular, and eutectic Si became fine and globular when Al-Si alloy ingots was heated up to semi-solid condition. Diameter of the globular primary crystal was about 90 ·m.
