摘要： The invention relates to a lance used to introduce reactants into molten metal, e.g. steel and aims to provide a lance of improved service life. The lance of the invention comprises an inner tube (21) and a refractory casing (25), the inner tube having an inlet (22) adjacent one end and an outlet (26) adjacent its other end, whereby reactant can be injected through the lance, in which the inner tube (21) is spaced from an outer tube (23) to provide an annular air gap (24) between the two tubes, the refractory casing (25) being provided on the outer tube (23) and a gas pipe (27) extending between the inner and outer tubes (21,23), the gas pipe (27) having its outlet adjacent the region of the outlet (26) of the inner tube (21), whereby gas passing through the pipe (27) can exit to atmosphere through the annular air gap (24).

摘要： The invention relates to a desulphurising agent for molten metal, especially pig iron, which consists of coated particles of magnesium.
The object of the invention is to provide a highly effective desulphurising agent that does not suffer from problems of hygroscopicity and abrasion and desegregation of the components during storage and transport.
The invention provides a desulphurising agent in the form of coated particles of magnesium having a first coating in contact with the magnesium of silica of finely divided structure in colloidal and/or amorphous and/or crystalline and/or fumed form. This coating acts as lubricating agent and slag liquifying agent for further coatings. The further coatings may be of highly reactive desulphurising agents and further protective coatings and coatings containing fluxes and agents to remove nitrogen and/or oxygen may also be applied.摘要翻译： 本发明涉及一种熔融金属脱硫剂，特别是生铁，其由镁的包覆颗粒组成。 本发明的目的是提供一种高效脱硫剂，其在储存和运输期间不会受到吸湿性和组分的吸湿和脱胶的问题的影响。 本发明提供了具有镁的涂层颗粒形式的脱硫剂，其具有与胶体和/或无定形和/或结晶和/或热解形式的细碎结构的二氧化硅镁接触的第一涂层。 该涂层用作进一步涂层的润滑剂和渣液化剂。 另外的涂层可以是高反应性脱硫剂，并且还可以应用包含用于除去氮和/或氧的助熔剂和试剂的其它保护性涂层和涂层。

摘要： Method of making wire-like treatment agent for metal melts e.g. ferrous ones comprises heating metal tube (1) e.g. of steel, introducing into the tube (1) a melt (3) having a temperature below melting point of the metal of the tube and comprising a reactive metal e.g. magnesium and cooling the tube (1) and the melt inside it to solidify the melt in the tube (1). Wire-like treatment agent itself comprises solidified melt (11) comprising a reactive metal encased in a preformed tube (1) of metal of higher melting point than that of the reactive metal.
