CASTING COMPOSITE INGOT WITH METAL TEMPERATURE COMPENSATION

摘要

An exemplary embodiment of the invention provides an apparatus for casting a composite metal ingot. The apparatus comprises a direct chill casting apparatus having a casting mold with at least two chambers for casting a composite ingot, troughs for supplying streams of molten metal to said at least two casting chambers, at least one temperature sensor for monitoring inlet temperatures of one or more of said streams of molten metal at positions adjacent to inlets of the casting chambers fed with said streams, a device for comparing said monitored temperatures from said at least one temperature sensor with predetermined set temperatures for said one or more streams to detect temperature differences for said streams, and a controller for adjusting a casting variable that affects molten metal temperatures entering or within the casting chambers by an amount based on a temperature difference detected for at least one of said streams.
