  • Patent number: 4168736
    Abstract: It is known to fill errosion holes in ingot mould bottoms, and other holes in ferrous metal bodies, with metal produced in situ by exothermic reaction. By the present invention, the exothermic composition is used in conjunction with a particulate refractory material. The refractory is bound by a matrix of solidified slag, produced by the reaction, to form a non-metallic filling having a working surface providing a high resistance to thermal shock. A metal phase is produced by the reaction but is merely incidental.
