FIELD: metallurgy. ^ SUBSTANCE: invention relates to metallurgy field, particularly it relates to facilities provided for blowing off liquid melt by gaseous oxidant. Tuyer contains body, connected from the one side with branch, allowing outlet port, and from the other side-with drive assembly, containing power drive, interlocked with rod of the other power drive, on which it is rigid punch-stick. Controlled drive is interlocked with launching trigger, fixing punch-stick over a distance. Supply duct of burning gases is implemented in the form of pipe, located lengthwise punch-stick on the block of pipe branch. Additionally one end of pipe is implemented as envelope punch-stick and located in outlet port of branch with ability of shift sideways from it. ^ EFFECT: reliability and safety growth of tuyer operation. ^ 5 dwg |
