以炼钢工艺中转炉炉体支撑装置的发展历程为线索,通过对几种典型的炉体支撑形式进行结构分析,阐述了卡板夹持联接以及法兰螺栓联接型式被淘汰的原因。结合工程实际应用,分析了3点球铰支撑结构的优缺点,总结了下悬挂结构在转炉炼钢工程应用中的优势,论证了下悬挂结构的静定系统属性,针对下悬挂装置的静定系统属性提出应用中的注意事项即机构设计上增设安全挡座、对各连杆的材质和热处理提出严格要求、各支撑件与炉体以及托圈的焊接必须严格保证质量、生产实际中注意检查该机构的工况,以便及时发现问题。
Taking the development history of converter furnace body supporting device in steel making process as a clue, the paper analyzes the structure of several typical furnace body supporting forms, and expounds the reasons why the card board clamping connection and flange bolt connection type are eliminated. The advantages and disadvantages of the three-point ball joint support structure are analyzed. The advantages of the lower suspension structure in the converter steelmaking project are summarized. The properties of the static suspension system are demonstrated. System attributes put forward the application of note that the design of the organization to add a safety barrier on the connecting rod material and heat treatment put forward strict requirements of the support and the furnace and the support ring welding must be strictly guaranteed quality, pay attention to the actual production inspection The conditions of the agency in order to detect problems in time.
