摘要： The present invention provides a cored wire injection process for introducing fluxes and alloying additives in liquid steel bath. The bath temperature and chemistry of the liquid steel is adjusted according to requirements in a secondary treatment unit. The additives are released from the cored wire, while controlling the zone of release. The yield of the additives can thus be controlled by changing dimension of the cored wire and speed of injection to suit the grade of steel processed and the treatment temperature. The zone of release is preferably close to the bottom of the ladle and the diameter and sheath thickness of the cored wire are preferably more than 13 mm and 0.4 mm respectively.

摘要： Disclosed is a method for conditioning slags and dust accumulated during the production of high-grade steel or during trash incineration. According to said method, the molten slags are treated with H2O vapor such that metal halides are converted into metal oxides and hydrogen halides, and the obtained hydrogen halide is withdrawn. The slags that are conditioned in said manner can be used for producing hydraulically active aggregates for cement, the recovery of optionally contained zinc being substantially facilitated.
