Abstract
A method and apparatus for continuously casting metal includes a tundish having edge seals and risers positioned at an outlet portion thereof . The edge seals and risers are configured to reduce the depth of molten metal adjacent the tundish sidewalls such that a lesser volume of molten metal contacts a driven casting surface to permit rapid solidification of edge portions of a cast strip. The edge seals and risers also are configured to form a meniscus between the seals and casting surface to effectively seal a gap between the tundish sidewall and continuous casting surface to prevent molten metal leakage therethrough. Preventing molten metal flow through the gap between the casting surface and sidewalls eliminates the requirement for a mechanical seal during continuous casting of molten metals.
