(54) Cast-iron ingot mould for use in the production of steel ingots and method of manufacturing the mould


(57) 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): wherein the Si-content is smaller than the Mn-content.
