ABSTRACT:
Apparatus and method for continuous casting of amorphous or polycrystalline metal strip from a melt. The molten metal is delivered from a reservoir (2) to a moving chill surface, preferably a cylindrical roll (1) through an orifice (3) in the reservoir (2). The gap between the reservoir (2) and the chill surface (1) is not fixed as in prior methods but is variable due to a resilient bias on the reservoir toward the chill surface. A pivot (10) and counterweight (11) are convenient apparatus for resiliently biasing the reservoir. The small portion of the reservoir (2) therefore rides lightly upon the molten metal film delivered to the chill surface or upon the solidified metal strip. The variable gap allows better control over the process and better quality surfaces on the metal strip.
