"Cast-iron ingot mould for use in the production of steel ingots and method of manufacturing the mould" ABSTRACT OF THE DISCLOSURE Cast-iron ingot moulds for use in the production of steel ingots suffer from the risk of broken feet, which reduces their average useful life. This is counteracted by increasing the P- content of the cast-iron and in particular by casting the ingot mould from a cast iron having the composition (by weight): C 3.8 - 4.7 % Si 0.55 - 1.15 % Mn 0.74 - 1.3 % S 0.01 - 0.035% P 0.14 - 0.195% rest Fe and usual impurities wherein the Si-content is smaller than the Mn-content.
