摘要： Steelmaking additive compositions and process of use, said compositions providing flux solubilization, desulfurization and/or removal of inclusions. The compositions comprise from about 25 to 50 wt % lime and about 75 to 50 wt % of a compound selected from the group consisting of bauxite and mixtures of calcium aluminate and bauxite; alternatively, the compositions comprise from about 40 to 70 wt % CaO, 20 to 50 wt % Al.sub.2 O.sub.3 from bauxite or mixtures of calcium aluminate and bauxite and 0 to 30 wt % MgO. The process consists of the addition, in the course of steelmaking utilizing electric furnace, basic oxygen furnace, AOD furnace or open hearth furnace means, of the steelmaking additive compositions of the invention to either the furnace, ladle and/or tundish.

摘要： A refractory plug for blocking the tap hole of a steel making vessel or transfer ladle containing molten steel covered by a layer of slag and for minimizing turbulence caused by vortexing. The plug comprises a body having an inverted cone-shaped bottom and having an integral top portion projecting axially from a top base surface of the cone-shaped bottom portion. The plug is added to the melt just prior to or during the tapping operation to minimize vortexing and to plug the tap hole prior to egress of the slag.
