三钢8号高炉炉况失常及恢复处理

本文对三钢8号高炉(420m~3)炉况失常过程、恢复处理及失常原因进行总结分析。在高炉炉况失常后通过高炉各种操作制度综合调节及降料面炸瘤,复风后高炉操作炉型得到纠正,实现炉况恢复稳定顺行。     

安钢1号高炉异常炉况下降料面操作实践

目前,高炉面临巨大的环保压力,限产、闷炉情况时常出现,在高炉炉役后期炉身冷却壁大量破损和严峻的环保形势要求下,高炉在长期闷炉开炉后,经过4天的短暂炉况恢复,被迫进行降料面停炉操作。通过对炉缸状况的科学分析,制定安全合理的停炉方案、严格控制高炉在恢复炉况和停炉期间的操作参数,实现了高炉在炉缸异常状态下的安全停炉。

榆钢1^#高炉快速复风实践

长期休风后能否快速全风作业是炉况成功恢复的关键。本文通过总结高炉长期休风前的准备及炉况恢复过程和失误,寻找了一种快速恢复炉况的方法。从而为钟式炉顶高炉更换大钟后快速恢复炉况奠定实践基础。     

长钢3号高炉喷补造衬实践

长钢3号高炉通过合理地选择喷补料，合理组织人员，根据工艺要求严格控制喷补的工艺参数，采用遥控喷补技术对3号高炉进行短时间造衬，使高炉在较短时间内恢复了正常炉型，高炉冶炼得到了恢复和进一步强化。     

酒钢4#高炉炉况失常恢复实践

酒钢磨煤机到理4#高炉（450m^3）在2006年5月5日-5月14日磨煤机年修结束后。随着煤比、富氧的快速提高。高炉各项技术经济指标取得了明显的进步。但由于煤比提高后频繁限制用氧量，导致理论燃烧温度降低。炉缸工作逐步变差，最终导致炉况失常。恢复过程中出现反复，高炉休减风频繁，恢复难度加大．导致此次炉况恢复时间长达半个月之久。     

喷补造衬技术在包钢3#高炉上的应用

通过合理地选择喷补料，采用遥控喷补技术对包钢3^#高炉进行短时间造衬，严格控制喷补的工艺参数，使高炉在较短时间内恢复了正常炉型，高炉冶炼得到了恢复和进一步强化。     

攀钢—高炉炉况失常后恢复期间的调查及分析

自1995年11月起，攀钢—高炉炉况一直不太稳定，生产水平波动较大，尤其是1996年3月下旬炉况再次恶化，为了尽快使之恢复正常，攀钢炼铁厂组织了炉况恢复攻关。在一高炉炉况恢复期间，对其进行了跟踪调查，据此进行了分析讨论。
