摘要: Disclosed herein is an apparatus for blowing a powdery refining agent into a refining vessel (21) which is adapted to blow the powder into a molten metal bath (22) of the refining vessel together with a refining gas by feeding the powder from a pressure vessel (27) to a main pipe (24) for the supply of the refining gas. The pressure vessel is connected to the main pipe through a plurality of transportation pipes (33,35) each provided with an on-off valve (36) and connected to a secondary gas pipe (38) for introduction of the refining gas downstream of the on-off valve(36). The secondary gas pipe (38) is provided with a flow control valve (39).
