The tundish car transports the tundish, which acts as a buffer between the ladle and molds during steel casting. The tundish car has a steel frame with wheels made of En-8 material that are driven by a drive unit. It also has a launder underneath to handle slag. The tundish promotes the flotation of inclusions in the liquid steel by providing adequate retention time before the steel flows into molds in a controlled manner via a flow control system.
