Abstract
A preformed expendable lining of high density, erosion resistant, castable refractory material is provided for a metallurgical vessel, such as a tundish. The lining is integrally formed in one piece and has a floor, walls, and at least one integrally formed flow control device. The flow control device may comprise a pair of upright baffles with apertures (some of them angled to the horizontal) for the passage of molten metal; or may comprise dams and weirs. The lining is particularly useful for the pour area of a T-shaped tundish, or a similar area for a conventional trough shaped tundish.
