摘要： A lance for feeding an additive wire into a quantity of molten metal below the surface of the molten metal. The lance has an inlet end which receives additive wire and an outlet end which dispenses the additive wire. The lance has an exterior sleeve of cardboard which has an inner surface. A portion of the inner surface of the exterior sleeve contacts an interior sleeve made of a refractory material. At the inlet end of the lance is a cardboard inlet outer sleeve and a cardboard inlet inner sleeve inside of the outer sleeve.
The lance can have a coupling for fitting to a wire feeding apparatus.摘要翻译： 用于将添加剂线材供给到熔融金属表面下方的一定数量的熔融金属的喷枪。 喷枪具有容纳附加线的入口端和分配添加线的出口端。 枪具有具有内表面的纸板外套。 外套筒的内表面的一部分接触由耐火材料制成的内套筒。 在喷枪的入口端是外套筒内的纸板入口外套筒和纸板入口内套筒。 喷枪可以具有用于装配到送丝装置的联接器。

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： A metallurgical process involves providing an ingredient enclosure and placing a plurality of granules of a first material in the ingredient enclosure. The first material contains a first ingredient in a metallurgical process. A metallurgical process furnace having a chamber in which ingredients for the metallurgical process are added is provided and the ingredient enclosure and the first material are added to the chamber. The chamber is heated after the addition of the ingredient enclosure and the first material to the chamber, although it may also be heated prior to such addition. In one form, the granules comprise mill scale and the metallurgical process furnace is a blast furnace.
