A refractory lining mass which has a long service life in view of its resistance to metallurgical erosion contains, in addition to the usual granular base material (e.g. quartzite, mullite), at least one deoxidizing agent for the oxide(s) of the metal (e.g. iron- carbon alloy) to be melted in the furnace. The agent is present in any amount of 0.1 to 5% by weight of the mass and preferably has a maximum grain size equal to that of the granular base material. The mass may also contain refractory fibres of the same or similar composition as the base material, the fibres having a diameter of up to 50 mu m and being present in an amount of 0.1 to 0.5% by weight of the mass. |
