Abstract

1281684 Hot tops FOSECO TRADING AG 9 July 1969 [4 July 1968] 32019/68 Heading C3N [Also in Division D2] A composition suitable for use in the production of hot top linings or casting riser sleeves comprises 15-50%, preferably 20-30% by weight of fibrous material, 40-80% by weight of refractory material and 0À5-10% by weight of a binder material, the said fibrous material being wholly inorganic or containing up to 40% of its weight of organic fibrous material and the said refractory material consisting in whole or in part of bubble alumina, hollow silica microspheres, calcined rice husks or pozzolana. The inorganic fibrous material may be of calcium silicate, aluminium silicate, aluminosilicate, asbestos, slag wool, rock wool, mineral wool or metal fibres. The organic fibrous material may be wood pulp (paper pulp), wood flour, cotton waste, rag stock or waste synthetic staple fibre, e.g. nylon, polyester or acrylonitrile fibres. Further refractory materials specified are silica flour, olivine, chamotte, alumina or any refractory silicate. The grain size of the refractory material is preferably less than 325 B.S.S. mesh. The binder material may be sodium silicate, gums, cereal flours or thermosetting resins, e.g. phenol-formaldehyde, and urea-formaldehyde resins. A combination of phenol-formaldehyde and urea-formaldehyde resin is most suitable. The hot top linings and casting riser sleeves are produced by forming an aqueous slurry of the ingredients of the composition and expressing the liquid therefrom to deposit a body of the solid ingredients in the required shape. The shaped elements may be given a surface coating of a refractory material, e.g. zircon, to increase the resistance of the elements to metal penetration.
