ABSTRACT:
An article of refractory holloware for use in a runner assembly for casting molten metals e.g. ferrous metals, has at least one inner surface adapted to increase the internal surface contact area of the article. The surface is so arranged as to effect at least two abrupt changes of direction of flow of molten metal flowing through the article. Use of the article minimizes the level of non-metallic inclusions in ingots and castings.
