Abstract—In an experiment, insulating inserts are introduced in the blast channel at the air tuyeres of blast furnace 5 at PAO Severstal, so as to decrease the heat losses. The experiment shows that two thirds of the inserts remain intact during tuyere operation. Most often, the tuyeres disintegrate near the gas slot—in particular, between the gas channel and the flange. Insert life may be increased if the slot in the insert and its junction with the gas pipe are protected by means of a thermostable seal. In manufacturing the tuyeres for blast furnaces 1 and 2 at PAO Severstal, the inserts are elongated in the nozzle region, with decrease in the heat losses.
