摘要
简要介绍针对高炉热风炉支管波纹补偿器出现的腐蚀、开裂等故障,开展的适应性优化改型工作。通过改变材质提高补偿器抗腐蚀性能,改变波纹位置和数量减小系统应力消除频繁开焊跑风隐患,修复后的补偿器各种性能指标能达到原设计要求,延长使用寿命,满足生产需要,为修复补偿器提供了可借鉴的经验。
The paper briefly introduced the corrosion, cracking and other problems emerged in the tipple compensator of hot-blast stove branch pipes and the Through changing the material to improve the corrosion adaptive optimization and retrofit carried out. resistance of compensator, sition and number to decrease the system stress further to eliminate the frequent the various performance indicators of compensator after repair could meet the ments, prolong the service life and meet the production needs, having provided the repairing of compensator. changing the ripple posealing-off hazard, and original design requirereference experience for
