WebThe tundish has the function of storing and distributing molten steel in the continuous casting production process to ensure the continuity and automation of the production … WebIn continuous casting, it is common to close single or multiple submerged nozzles of multi-strands tundish to adapt to production rhythm due to insufficient liquid steel or equipment failure. However, the closure of the nozzle will change the flow field in the tundish and further affect the removal efficiency of inclusions in the tundish. For this reason, based on … Webladle treatment and vacuum process. They have to be maintained during continuous casting. Nevertheless steel products contain impurities which locally do harm to sensitive applications. When talking about cleanness of steel, oxide inclusions are the main point of discussion.

WebJul 19, 2024 · A slag inclusion firmly attaches to the casting, reducing the mechanical characteristics of the final product. It usually occurs when non-metallic materials cause irregular crusts on the casting surface. The casting defect is ribbon-like entrainment or pocket with sharp edges and irregular shapes. WebThe transformation of non-metallic inclusions in the first continuous casting bloom of a bearing steel was studied through industrial trials and theoretical calculations. The spatial …

WebClogging is a phenomenon that usually occurs in the flow control system during the continuous casting of steel. It describes the build-up of deposits at various positions in the continuous casting machine. The submerged entry nozzle (SEN) between tundish and mold is the area most frequently affected by the appearance of clogging.
