  • Method for the continuous casting of thin metal products
    Patent number: 5083603
    Abstract: In continuously casting thin metal products such as sheets or strips, molten metal is introduced into the gap between a rotating cooled main cylinder and a counterrotating roller spaced from the cylinder to form a gap corresponding to the thickness of the desired product. The metal, in cooling, forms solidifying skins on the respective rollers. The peripheral speed of the roller exceeds that of the cylinder by 2 to 20%. The resulting product is substantially free of the surface defects characteristic of prior art processes.
