Abstract:
An apparatus for casting metal strip comprisinga pair of parallel casting rolls forming a nip between them; a metal delivery system for delivering molten metal into the nip to form a casting pool of molten metal supported above the nip; a pair of pool confining end closures disposed one at each end of the pair of casting rolls; roll drive means to rotate the rolls in opposite directions to deliver a cast strip downwardly from the nip; strip transport means to transport the strip away from the nip; strip inspection means to inspect the strip as it is transported away from the nip to determine a pattern of thickness variations along the strip due to eccentricities of the casting roll surfaces; and control means to impose a pattern of speed variations on the rotation of the casting rolls determined by said pattern of thickness variations so as to reduce the amplitude of the thickness variations.
