    摘要： Injectable composition for desulphurizing molten ferrous metals, especially iron, comprises alkaline earth metal, preferably magnesium, and sintered mixture of lime and at least one fluxing agent. Magnesium is preferably 8 to 60% of composition and lime preferably is 45 to 95% of the sintered mixture. Fluxing agent is preferably alumina and fluoride. Composition enables rapid and efficient desulphurization and does not give large amounts of slag.

    摘要： Apparatus for protection of graphite electrodes of electric arc furnaces e.g. for steelmaking to reduce loss of graphite from sides of the electrode by oxidation has at least one generally arcuate spray unit and means for moving the spray unit towards and away from a side of the electrode. The spray unit has means for spraying protective matter towards the center of its arc. The apparatus permits protection of the part of an electrode between the electrode clamp and the furnace roof without removing the electrode from the roof.

    摘要： The disclosed invention relates to the field of ceramics and concerns an open-cell expanded ceramic which may be used in the form of a deep-bed filter, and a process for the production thereof. The primary object is to produce an open-cell expanded ceramic by a simple and economical process. This object is attained by an open-cell expanded ceramic in which the inner cavities, cracks and the porosity of the ceramic members are filled partially or completely by one or a plurality of metal and/or ceramic phases and/or glass phases. The open-cell expanded ceramic is also produced in that during or after sintering the cavities, cracks and the porosity of the ceramic members are partially or completely filled with a melt or a suspension which melt below the melting temperature of the expanded ceramic, have a coefficient of expansion similar to the coefficient of expansion of the expanded ceramic, and a very good wetting capacity, and only react partially or not at all with constituents of the expanded ceramic.
