Abstract
A proposed method to increase the service life of the heat-insulating insert in the air passage of the blast furnace tuyere suggested gluing heat-resistant siliceous fabric onto its outer surface, and to reduce heat loss and increase the tuyere resistance to burnout, fixing a ceramic disk to the end of the tuyere’s nose. The necessity of measures to increase the service life of a heat-insulating insert in the tuyere was justified by simulating its stress state in Ansys. The use of heat-resistant siliceous fabric on the entire outer surface of the insert allowed a more than twofold increase in the insert’s service life compared to the option when the fabric was glued to the insert part from the flange to the gas pipe. Using simulation of the tuyere’s thermal state in a DEFORM–2D environment and industrial experiments, the possibility of reducing heat loss and protecting the tuyere from burnout by thermal insulation of the end of its nose using a ceramic disk is shown.
