Abstract
In the addition of alloy additives to molten metal baths, under conditions in which there is an absence of substantial external stirring, such additives tend to distribute unevenly within the molten bath. Homogeneous distribution of such additives is achieved by first coating fragments of the alloy additive with a water-base mixture containing from about 2 to 30% oil dispersed therein and thereafter adding the fragments to the molten steel bath.
Claims4
In the addition of alloy additive fragments to a massive molten metal bath, said addition being effected under conditions in which the degree of stirring of said bath is ineffective in achieving a homogeneous distribution of the additives within the bath,
- the improvement for significantly improving the homogeniety of said distribution, which comprises, prior to the addition of the additive to the molten bath, applying an aqueous mixture to said fragments so as to provide an aqueous film thereon, said mixture consisting essentially of 2 to 30 weight percent oil dispersed in water.
