Abstract
A fused cast refractory containing at least 5% b.w., and preferably at least 11% b.w., free carbon intermingled with randomly oriented metallic carbide crystals, analytically comprises carbon and at least 20% b.w. of one or a mixture of metals selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W. Metals from the group consisting of Si, Mn, Fe, Co and Ni may be mixed with metals of the first group (provided first group metals form at least 10% of the casting), and up to 10% b.w. O2 and up to 10% b.w. N2 (but not more than 15% b.w. of both together) may be included with up to 5% b.w. of impurities, e.g. Al, alkali and alkaline earth metals, rare earth metals, S and P. A mixture of the metal carbide and carbon or graphite or of the metal and/or metal oxide, e.g. ilmenite, with excess carbon, is melted in an electric arc-melting furnace having graphite electrodes or in an electric induction-melting furnace having a graphite lining. A neutral or reducing atmosphere should be maintained, and the molten charge is poured into a graphite mould where it solidifies rapidly to produce a cast refractory in which at least 40% b.w. of the crystals are randomly oriented, with graphite randomly interwoven. Specific examples are described.
