Abstract

Molten metal is fed to a caster in a continuous casting operation through a distributor that divides the molten metal into four streams flowing in circulating patterns from the central axis of the caster. Each stream sweeps first along the longer side wall of the caster toward the corner, then back along the shorter side wall toward the center line. The result is a higher degree of fragmentation of metal crystals as they form, and a better distribution of the fragments across the caster cross section, as well as a more even temperature distribution.
