Abstract
A quiescent melt handling system includes a melting furnace and a holding furnace communicating with the melting furnace for holding a molten metal melt. The holding furnace has a relatively large surface area and a relatively shallow depth, having a width to depth ratio in the range of 4-100 to 1. Also provided is structure in the holding furnace for separating inclusions from the melt in the holding furnace. A mold communicates with the holding furnace. A counter gravity casting system, which might comprise a vacuum assisted casting system, draws the melt into the mold.
