摘要：The invention relates to an injection device for the reliable introduction of afluid into a metallurgical vessel having a refractory lining, the device being removablyinsertable in the lining; comprising a refractory first body () and a refractory second body

() fittingly assembled, the first body () being made of a refractory material lesspermeable to the fluid than the material of the second body (), the first and secondbodies having each a surface () adapted to contact molten metal; and having each fluidpassages () extending from fluid feeding means () to a surface () adapted to contactmolten metal, the relative flow resistance of the fluid passages () in the second body ()being higher than that of the fluid passages () in the first body (), the fluid passages () inthe first body () being constituted of slots or bores. According to the invention, the fluidpassages () in the first body () are independent from the fluid passages () in the secondbody (). Such an injection device permits the reliable introduction of a fluid into ametallurgical vessel even when the injection device has already been used.
