Abstract
A system for in-line alloying of a molten metal stream comprises: means for controlling mass flow rate of the stream; means for adding alloying material to the stream at an adjustable rate; means for determining chemical composition of the stream downstream from the material adding means, preferably at timed intervals; and means for adjusting the rate at which alloying material is added to the stream based on mass flow rate and the extent to which the determined stream composition differs from a desired composition. A method for conducting in-line alloying and analysis of a continuous metal stream is also disclosed.
