Abstract
1,272,845. Mould linings; ingot moulds. FOSECO INTERNATIONAL Ltd. 2 March, 1970 [12 March, 1969; 8 Dec., 1969 (2)], Nos. 13063/69, 59822/69 and 59823/69. Heading B3F. [Also in Division C3] Ferrous metals are cast in an ingot mould whose walls or the base-plate thereof have been coated either with an aqueous liquid refractory dressing comprising particulate refractory material consisting of or including magnesia which particulate refractory material has a "residual hydration ability" of less than 4% by weight and, as binding agent, an alkali metal silicate or a refractory dressing precursor comprising the particulate refractory material previously specified and a solid alkali metal silicate. The percentage residual hydration ability of the material is defined as the percentage weight loss on heating a dry sample of the hydrated material at 600‹ C. for 2 hours. The magnesia should preferably have a low calcium oxide content and preferred magnesias are dead burnt magnesites. The particulate refractory material may also include alumina, titania or zircon whilst the magnesia may contain iron oxide as impurity. The alkali metal silicate used is preferably sodium silicate, most preferably sodium metasilicate. The amount of water used in the liquid dressings should preferably be sufficient to cause hydration of the alkali metal silicate to at least 10 H 2 O. When sodium silicate is used the magnesia and sodium silicate react in use to form the refractory magnesium silicate "forsterite". Optional ingredients specified are a Xanthomonas colloid suspension agent and a particulate suspending agent, e.g. bentonite.
