顶燃式热风炉1979年在首钢投产，90年代以后，随着高炉大型化，大型顶燃式热风炉燃烧口的寿命只有4～5年，严重制约了高炉生产和指标的改善。为了提高燃烧口寿命，在对砌体塌落进行调查的基础上，对燃烧口破损原因进行了研究，并提出了改进措施。
The hot stoves with top combustion chamber was put into operation on Shougang's No.2 blast furnace in 1979. With the blast furnace volume enlargement finished in 1990s, the burner life was kept as short as 4-5 years and furnace production was limited. On the basis of investigation the mechanism of burner failure has been clarified. The result suggests a way to prolong campaign of burner.
