[0002] The tuyere platform above the blast furnace's iron outlet is subjected to high-temperature baking by molten iron for a long time, and the air temperature can reach 500°C. The steel frame and bottom plate of the tuyere platform crack and deform due to the heat, and the bottom plate cracks and brickwork breaks and falls off. When iron is tapped, hot air flows up from the damaged gaps and carries gas with it. The cracking and falling of the bottom plate, the high temperature and the gas pose a huge safety hazard to the passage and maintenance of on-site personnel.

[0003] It is difficult to repair hidden dangers in steel structure, bottom plate and brickwork. After removing the brickwork and cutting off the bottom plate, the steel structure, the bottom plate and the brick layer need to be reinforced again. Moreover, the steel structure cannot be reinforced after severe cracking, and the steel structure, especially the steel beam, must be replaced. The construction time is long, generally taking 3 days, which affects the production of iron in the blast furnace. Especially when there are only two iron holes, one side is under maintenance while the other side is producing iron. There are great production, equipment and safety hazards. In order to solve the above problems, a thermal insulation protection device for the tuyere platform above the iron hole of the blast furnace is proposed. Summary of the invention
