沙钢5800m~3高炉成功处理长期事故休风实绩

对沙钢5800m~3高炉成功处理长期事故休风的经验进行了总结。主要经验是:高炉紧急休风后,最大限度地采取保温措施;复风之初加入足够净焦;净焦中适当加入萤石,以保证炉渣的流动性;送风初期用少量风口送风,放慢冷料熔化速度,缓解处理过程中发生剧冷、甚至冻结的可能性;后续捅风口的次序坚持"连续"的原则。

Measures against Long Time Blowdown of 5800 m3 BF in Shagang

The paper summarizes the experiences in handling long time blowdown of 5800m~3 BF in Shagang,including holding temperature to the possible maximum extent after emergency blowdown,charging enough clean coke at the beginning of reblowing;adding appropriate amount of fluorite in clean coke to ensure slag liquidity,blowing air via few tuyeres at the beginning of blowing period to slow down melting speed of cold burden,minimizing the occurrence of sharp cooling,even freezing, continuously tuyere drilling in the ...
