Abstract
An expendable lining may be applied over the interior walls of a metal handling vessel for molten metal, e.g. a tundish. The expendable lining is usually applied over a relatively permanent, e.g. refractory brick, lining. If the expendable lining is formed by placing a suitable former inside the vessel to define a space corresponding to the desired lining, filling the space with particulate refractory material and heating, it has been found difficult to provide adequately uniform heating and to avoid distortion of the former. The invention provides a former for the in-situ manufacture of an expendable lining (22) in a molten metal handling vessel (20, 44), the former (23, 43) being a box-like construction to be inserted in the vessel (20, 44) in one-piece, in which the box-like construction (23, 43) comprises at least one central channel-shaped portion (24) and two end portions (25) each end portion (25) being constrained to be able to move in a sliding overlapping relationship with a or the central portion (24).
