Method of preparing a shot of semi-solid metal |
摘要 |
<p>By determining an amount of a metal to be prepared into a slurry in its liquid state, thereafter applying a motion to the melted metal via a mechanical or physical means when at least a part of the melted metal reaches a temperature below the liquidus temperature and cooling the melted metal in a slurry preparing container to prepare the melted metal into a metal slurry in a semi-solid state, and by concurrently making the semi-solid metal slurry in the slurry preparing container with a shape to be kept almost unchanged, and feeding the semi-solid metal slurry in a state wherein the shape is nearly kept as it is into the shot sleeve/prechamber of the part making machine, a semi-solid metal slurry with the non-dendritic (spherical) primary crystal particles being fine and almost uniform can be fed into the part making machine, with no need of any specifically complex process but with a simple system and plain equipment. Thus, a shaped part with high quality can be produced. <IMAGE></p> |
