Abstract
A method of continuous casting non-ferrous alloys which includes delivering molten non-ferrous alloy to a casting apparatus. The casting apparatus rapidly cools at least a portion of the non-ferrous alloy at a rate of at least about 100° C. thereby solidifying an outer layer of the non-ferrous alloy surrounding an inner layer of a molten component and a solid component of dendrites. The dendrites are altered to yield cast product exhibiting good resistance to cracking.
