摘要
由于发电用煤种类多、杂质含量偏高，可磨性较差，造成中速磨煤机磨辊耐磨寿命缩短。采用堆焊修复技术使磨辊的一次使用寿命由３０００ｈ提高到５０００ｈ。介绍了磨辊修复技术、设备、工艺。
Because coal for power generation varies widely and has high foreign substance content and low grindability,the life time of the rollers in medium speed pulverizer is shortened.The service life can be prolonged from 3,000 to 5,000 hours by applying wear proof built up welding to the rotor. This paper introduces the technology, equipment,and procedure used for roller repairing.
