Continuous casting machine with refractory tundish funnel and collector
A newly granted patent (Publication Number: US11958107B2) discloses a continuous casting machine with innovative features aimed at improving the casting process. The machine comprises a ladle, a collector with a unique opening design, a tundish funnel, and a coupling mechanism to seal the collector with the tundish funnel. The tundish funnel plays a crucial role in sealing the tundish with the ladle, ensuring efficient operation. Additionally, the design includes specific dimensions and shapes for optimal functionality, such as tapered openings and rounded corners in the collector and tundish funnel.
Furthermore, the patent details the use of compressible rings, slide gates, and varying angles in the outer surface of the collector to enhance the casting process. The machine's configuration allows for precise alignment of openings and controlled flow of molten metal, contributing to improved casting quality. The inclusion of resilient rings that compress when the ladle is lowered onto them adds a dynamic element to the design, showcasing a comprehensive approach to continuous casting technology. Overall, the patented continuous casting machine presents a sophisticated and efficient system for metal casting applications, with a focus on precision, reliability, and operational effectiveness.
