摘　　要：泥炮是高炉的专用设备,其主要功能是在不休风情况下完成高炉堵住铁口,使高炉快速进入下一循环的作业,高炉泥炮控制连杆频繁失效,给高炉正常生产带来极大的负面影响。分析了河钢股份有限公司承德分公司4座高炉泥炮控制连杆故障率偏高、制约高炉长周期稳定运行的问题。结合现场实际情况,制作一种新型泥炮控制连杆支座,该支座结构简单、造价低廉,可延长高炉泥炮控制连杆及关节轴承使用寿命,降低成本,为河钢股份有限公司承德分公司年创造效益269.16万元。Clay gun was the special equipment of blast furnace,of which the main function was to block the iron out-let under the condition of no blowing-down,thus the blast furnace could enter the next cycle quickly.The frequent failure of control connecting rod had a great negative effect on the normal production of the blast furnace.The high failure rate of the control connecting rod of four blast furnaces in Chengde Branch of Hebei Iron and Steel Company,restricting the long-term stable operation of blast furnace,was analyzed.According to the actual situation in the field,a new type of clay gun control connecting rod support was made,of which the structure was simple and the cost was low.The service life of the control connecting rod and joint bearing of blast furnace clay gun was pro-longed,and the purpose of low-cost operation was achieved as well,achieving an annual efficiency of 2.6916million yuan for Chengde Branch of Hebei Iron and Steel Company.
