Abstract
1325467 Casting refractory oxides L'ELECTRO-REFRACTAIRE 9 Oct 1970 [10 Oct 1969 28 May 1970] 48179/70 Heading B5A Refractory mouldings are formed by pouring into a cooled metal mould, a molten refractory oxide charge containing at least one gas generating substance, and solid fragments of a refractory oxide, preferably of the same composition, are introduced into the material poured into the mould as it is filled so as to distribute the fragments uniformly in the cast material, and the superficially solidified casting is removed to complete the cooling outside the mould, the mould being opened after a time long enough to avoid distortion but short enough to avoid cracking of the body. The oxides may be magnesia and chromite, the product thus containing magnesium oxide, chromium sesquioxide, silica, calcium oxide, ferrous oxide and alumina. The chromite may be at least partly Turkish chromite which evolves gases at the pouring temperature. After removal of the pouring funnel, a heavy plane surface to exert a pressure of 1-10 kg./dm.<SP>2</SP> may be placed on the pouring sear.
