三钢6号高炉大修开炉达产实践

Practice of Blowing-in and Reaching Design Capacity of Sansteel No.6 BF after Revamping

对福建三钢6号高炉大修后开炉达产操作进行了总结。通过设备可靠性运行调试,严格的烘炉操作,充分的试漏试压,精准的开炉料全炉焦比、碱度及装料位置、合理送风参数的选择,对送风后冶炼进程的有效控制,合理的首炉铁时间选择,料制的动态优化等实现了高炉顺利开炉、快速强化达产。

It is summarized the main operating experience in fulfillment of design output of Sansteel No.6 BF after revamping。Through equipment reliability operation commissioning,Strict the drying oven operation,fully the pressure leakage test,accurate selection a blowon program and coke ratio of the whole furnace、alkalinity and charging position,selecting appropriate blowing-in parameters,Effective control of smelting process after blowing-in,Reasonable selection the tapping time of first heat,Dynamic optimization of the charging system,Signifying rapid blowon and rapid design output fulfillment of the furnace.
