Abstract
A mold for continuously casting molten metal, which mold has a friction-reducing material disposed so that the surfaces of the copper liner and the steel backing plate of the mold bear against this material instead of directly against each other. Specifically, the friction-reducing material must possess a coefficient of friction significantly less than the coefficient of friction which results when copper bears against steel. Consequently, the restraint against thermal expansion is minimized, resulting in less distortion of the liner.
