Abstract
The utility model relates to a rotary type spray lance for metallurgy, comprising a lance, on which a driving setup is arranged for driving the lance to rotate by the axis, and the setup is installed on a fixing unit by several bearings. A stream channel is disposed in the lance. A rotary valve for connecting the feeding pipe with the stream channel is provided on the top of the lance, and a sidewise spout, which is connected with the stream channel, is provided at the bottom. The top and bottom parts can be detached from each other. The top part is arranged with mid-holes, and the bottom part is arranged with stuff-spraying pipes. The mid-holes and the stuff-spraying pipes are connected with each other, forming the stream channel in the lance.
