Title (EN) PRODUCTION OF METAL CASTINGS
(FR) PRODUCTION DE PIECES COULEES METALLIQUES
Abstract: front page image
(EN)Sound castings (1), free from aluminium pick-up, are produced in moulds (2) in which are located at places where it is desirable to promote directional solidification lining pads (9) made from a composition which comprises particulate refractory material, finely divided aluminium, an oxidising agent for the aluminium and a binder, and which is substantially free of fluoride salts, which contains a fibrous refractory material and which has a density of 0.3 to 1.1 g/cm3. The composition may be incorporated as a preformed pad, or as a flexible mat or mouldable mixture which can be dried or hardened chemically.
(FR)Des pieces coulees saines (1), exemptes de grippage d'aluminium, sont produites dans des moules (2) dans lesquels, aux endroits ou l'on desire provoquer une solidification directionnelle, des surepaisseurs de revetement sont prevues (9) faites avec une composition qui comprend un materiau refractaire particulaire, de l'aluminium finement divise, un agent oxydant pour l'aluminium et un liant, et qui est sensiblement exempt de fluorures, contient un materiau refractaire fibreux et possede une densite de 0,3 a 1,1 g/cm3. La composition peut etre incorporee sous forme de garniture preformee, de tapis flexible ou d'un melange moulable qui peut etre seche ou durci chimiquement.
