摘　　要：中国上海宝钢股份炼钢厂一炼钢转炉采用的是三点球面支撑系统,如更换三点球面支撑,则必须将转炉炉体整体顶升1020mm后才能完成三点球面支撑的倒运工作,原先采用的转炉安装台车加4*200t顶升系统可完成工作,但顶升过程稳定性较差,且耗费时间较长,成本高。为降低检修成本,减少施工时间,提高顶升过程的稳定性,我们引进了4*200t同步顶升系统,并将系统顶升的顶点从炉底上移到了托圈上部,将转炉炉体顶升复位时间从96小时降低到了4小时。A steelmaking converter using a three point spherical support system of China's Shanghai Baosteel Steelmaking Plant, changing of three spherical support, we must complete integral lifting 1020 mm of the converter body, then complete the reshipment of the three spherical support, the original converter should install 4 * 200 t lifting system, it can complete the work, but the stability of jacking process is poor, and high cost and time-consuming. In order to reduce the maintenance cost, reduce construction time, improve the stability of the jacking process, we introduce the 4 * 200 t synchronous lifting system, and lift the jacking top points from converter bottom to supporting ring top, also reduce the reset time of converter body lifting from 96 hours to 4 hours .
