ABSTRACT:
Two-drum, two-layer continuous casting method and apparatus for casting metallic strip from molten metal in which two closely spaced drums with parallel horizontal axes define the bite region between them. The drums are revolved in opposite directions at approximately the same surface speed with the surface of each drum moving downwardly in the bite region. The two drums are hollow and are internally cooled in a manner to keep their external surfaces at a temperature in the range from and including 100.degree. C. to 400.degree. C. The molten metal flows in a launder at controlled velocity toward the crest of each revolving drum, and the drum surface is travelling at speed faster than this controlled flow velocity, at least 1.5 times as fast for pulling a thin layer of the metal forward on each drum surface significantly faster than the metal was previously flowing in the launder, thereby significantly thinning the pulled layer of metal as it makes the transition from the slower moving mass in the launder to the faster travelling layer being pulled forward by the drum surface. The thin layer of metal on each drum surface is no more than about 0.15 of an inch thick and is in a liquidous/solidous state. These thin liquidous/solidous layers on the revolving drum surfaces as they are in the process of solidifying are carried down into the bite region between the drums. In the narrowest portion of the bite region the drums have a spacing in the range from 0.01 of an inch to 0.30 of an inch for melding these two solidifying liquidous/solidous layers together in the bite region to form a resulting thin cast strip moving downwardly from the bite region.
