Summary:This paper proposes to improve the durability of the heat insulating insert for the air passage of the blast furnace tuyere by applying a slurry coating to the tuyere’s inner surface. In addition, the tuyere installation variant after assembling and exposing it to hydraulic tests is considered, as well as heat loss reduction by attaching refractory fabric to the tuyere nose. The slurry coating applied to the insert’s inner surface has made it more durable by at least 30%. Theoretically, the insert can be made more durable when installed in the air passage after assembling the tuyere and exposing it to hydraulic tests. Studies have shown that the heat losses can be reduced by 10% on average by using refractory siliciferous fabric to ensure the heat insulation of the tuyere nose.
