辊道轴头断裂修复技术研究

Research on Repair Technique for Roller Table Ruptured Shaft Head

经研究实验5500厚板粗轧机输出辊道轴头断裂采用焊接修复办法强度不够，不宜采用。经过盈连接计算和应力校核，镶嵌轴修复方法是辊道轴头断裂修复的有效措施。

Through study and experiment, it shows that it is not strong enough to recover strength of the ruptured shaft head of exit roller table in 5500 heavy plate roughing mill by welding. It is not suitable to use this method. By calculating interference fitting and checking stress, inlaid shaft re- pairing method is an effective measure to repair the ruptured shaft head of roller table.
