| 20100172787 | NOVEL ADDITIVE COMPRISING LEAD AND/OR A LEAD ALLOY INTENDED TO TREAT BATHS OF LIQUID STEEL - The present invention relates to an additive in the form of flux-cored wire for treating baths of liquid steel with a view to obtaining steels having a high lead content. The additive comprising metallic lead and/or one or more lead alloys according to the invention for treating baths of liquid steel, and is in the form of flex-cored wire composed of a metal sheath and a finely divided filling material, the latter being composed of a powder of metallic lead and/or of lead alloy and of a powder containing a material capable of releasing a gas, which is inert with respect to the liquid steel, at the temperature of the liquid steel bath. Characteristically, the powder of metallic lead and/or of lead alloy includes a particle size fraction G | 07-08-2010 |
