Abstract
A crucible for use with a broken arm-type centrifugal casting machine includes an elongated base section and a top section which is generally in the shape of a half cylinder, a large portion of the top section being removed by a cavity which creates a crucible floor, left and right side walls and a generally funnel-shaped channel which extends to a front surface at the front end of the crucible to provide a discharge opening. The right side wall is always correspondingly higher than the left side wall and both the left side wall and the right side wall increase in height and slope over toward one another as they extend toward the front end of the crucible until they merge at a point on a head portion of the top section which is on the left side of the crucible. The crucible floor includes a portion which narrows in width as it extends toward the front end of the crucible and slopes downwardly from horizontal at an angle of between about 10.degree. and 20.degree., and another portion which also narrows in width as it extends toward the front end of the crucible and slopes downwardly from horizontal at an angle of between about 2.degree. and 6.degree. and concurrently downwardly from horizontal toward the right side of the crucible at an angle of between about 2.degree. and 6.degree. so as to provide a lowermost area of the crucible floor in the noted head portion.
