The upper nozzle 2 having the short length is used when the position of the top surface of the brick 4 and the tuyere 3 lowers due to eroding. The upper nozzles 2 having stepwise different lengths are therefore prepd. and are properly exchanged according to the eroding condition. The plug 1 is fitted and mounted to the upper nozzle 2 prior to fitting and mounting of the nozzle 2 into the tuyere 2 then the nozzle 2 is inserted into the tuyere 3 and is thereby fitted and mounted therein in order to avoid the mounting of the plug 1 in the vessel contg. the molten metal.
