    摘要: FIELD: The applied for invention lumped skull lining material relates to the ferrous metallurgy, in general, and to blast-furnace manufacture, in particular. It may be used while cast iron production in blast-furnaces.
    ESSENCE: The applied for invention skull lining material contains a titanium containing component and a flux component. The titanium containing component includes grains of ilmenite and/or pseudobrukite, and/or perovskite. The flux component is a connecting component and generally consists of alum silicates, calcium alum silicates and calcium alum ferrites, wherein content of the structural components is:
    grains of ilmenite and/or pseudobrukite, and/or perovskite
    51 -60%, vol.
    flux connection
    15 - 35 %, vol.
    pores
    the rest
    TECHNICAL EFFECT: The invention brings to the effective technical result which is effective guide of strong durable skull lining in blast-furnace metal receiver without any substantial disturbances into the melting process provided by the applied for invention changes in mineralogical composition and structure of the skull lining material aimed at ensuring its main properties.
