Abstract

Method of making a refractory for lining crucibles, ladles, vacuum chambers etc. for steel making and consisting of eutectic mixture of periclase and magnesium spinel comprises mixing 44% pure MgO and 56% pure Al2O3 heating to complete fusion at >2030 degrees C casting crushing and grinding to a fine powder, moulding the powder at 1-100 h bar and sintering at close to the melting point. The material has improved refractory props and working life compared with (a) Fe2O3 + iron spinel, (b) corundium + magnesium spinel.
