Реферат: Abstract: "APPARATUS FOR INTRODUCING SUBSTANCES INTO LIQUIDS E.G. METAL MELTS" For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt. The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C). Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91) (for gas or fluidised powder). Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25). Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91). Wire is fed along passage (B) to the melt; when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt. A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.
