摘要： 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, said powder of metallic lead and/or of lead alloy comprises a particle size fraction GR between 200 μm and 500 μm and said particle size fraction GR has the following characteristics: - through a 200 μm sieve: GR

摘要： The invention relates to a cored filler wire that includes an additive containing calcium silicate CaO.SiO
2 , adapted for treating so-called resulphurized special steel. The invention also relates to a method for making resulphurized steel using the above cored filler wire. The method of the invention is particularly adapted for treating solid inclusions present in aluminium-containing steel baths. The method of the invention can be used for preventing desulphurisation before the treating of the solid inclusions.

摘要： An end-piece for an additive guide tube is disclosed. Such an end piece may have a durable sleeve and a sloughable sleeve. The sloughable sleeve may have a channel through which an additive may be delivered, and the sloughable sleeve may reside in the through-hole of the durable sleeve and may be secured to the durable sleeve. When molten metal contacts the sloughable sleeve, the sloughable sleeve burns or melts and sloughs off, thereby preventing the molten metal and slag from sticking to the end-piece, which in turn prevents buildup of metal and slag.

摘要： The invention concerns a flux-cored wire for introducing additives into a molten metal bath comprising a metal sheath (5) containing an additive (6), which metal sheath is covered with an envelope (7) which, being combustible but without unwanted residues, momentarily delays heat propagation towards the flux-cored wire core. Said flux-cored wire is characterised in that above said combustible envelope, a metallic protection encloses the assembly formed by the additive, the metal sheath and the combustible envelope.
