Abstract
Methods of calculating the heart losses and temperature are adapted for the air tuyeres of blast furnaces. Using Excel software, the influence of a sprayed coating and a heat-insulating insert on the thermal state of air tuyeres is investigated. The presence of the insert reduces the heat losses through the blast channel more effectively than the application of an aluminum coating. The creation of an air gap between the insert and the inner wall further reduces the heat losses. With increase in thickness of an insert introduced without a gap in the blast channel, the heat losses through the channel are reduced. In the presence of a gap, its thickness has practically no influence on the heat losses.
