Study and disposal of the frequent tuyere damage of No.4 BF at Masteel

：１９９８ 年一季度，马钢二铁厂４＃ 高炉风口大量烧损，严重制约了高炉的生产，一季度共烧坏风口３９ 个，是历年来少见的通过采用萤石、锰矿及空焦洗炉等措施后，风口烧损趋于缓解。

During the first quarter of 1998,the tuyeres of No.4 BF at No.2 Ironmaking Plant of Maanshan Iron and Steel Co.Ltd were damaged in a large scale, thus the production was restricted. It was a rare situation over the years that 39 tuyere were damaged within a quarter. The situation of tuyere damage tended to alleviate and the production returned to normal by taking some technical measures such as adding fluorspar, manganese ore, coke blank slugging and so on.
