摘要
利用振动时效技术消除热风炉穹顶壳体焊缝焊接残余应力,选用了最大激振力为50KN的LCDVSR-07型振动消除应力系统,激振点选在壳体顶部人孔法兰上,取得了明显的应力消除效果和较好的经济效益并缩短了工期。
Residual stress elimination for round roof of hot air stove of blast furnace using vibration aging technbique from LCDVSR- 07 vibrator which provides maximum vibration force being 50KN. The vibrating point is selected at place of the flange for manhole. The result is effective with better economic efficiency and Shorten the construction period.
