2015年第 期5 冶 金 动 力 总 第 183 期 METALLURGICAL POWER 71 加强环冷机的改进，全面提升球团焙烧效果 倪晋权 （马鞍山钢铁股份有限公司第三炼铁总厂，安徽马鞍山 243021） 【摘 要】针对球团环冷机存在回转体跑偏、隔断门易损坏、水封漏水、热平衡失调等问题，从操作工艺、耐 火材料的结构、设备本身存在的问题等方面进行分析，通过对环冷机轨道加固、受料库结构的改进、隔断墙改进 等一系列措施加以改进，收到良好效果。实施后效果表明，改进后的环冷机运行平稳，链窑系统内热平衡状态良 好，煤气的消耗量大幅度降低，生产线更加趋于稳定。 【关键词】环冷机；水封；轨道；隔断门 【中图分类号】TF046 【文献标识码】B 【文章编号】1006-6764(2015)05-0071-03 Upgrading Transformation of the Circular Cooler to Improve the Baking Effect of Ore Pellets NI Jinquan (The No.3 Ironmaking Works of Maanshan Iron and Steel Co., Ltd., Maanshan, Anhui 243021, China) 【 】The problems of the revolving mechanism running off-track, damage of the Abstract partition door, leakage of water sealing and thermal misbalance in the pellet circular cooler wereanalyzed from theaspectsof operation process, refractory structure and the equipment it- self. Good results were achieved after taking improvement measures including reinforcement of the cooler tracks, optimization of incoming material structure and modification of the partition door. The upgraded circular cooler has operated stably, thermal balance has been obtained in the chain oven, gas consumption significantly reduced and the production line run more steadily. 【 】circular cooler;water sealing;track; partition door Key words 1 概述 机的故障不断，特别是其回转体跑偏现象严重，导致 环冷机是球团链窑生产线的三大主机之一，担 水封拉坏，回转体轨道损坏、脱落以及支承辊损坏， 负着球团矿的进一步焙烧、冷却的功能。因此如何保 环冷机风箱密封损坏、台车漏料等。故障统计如表 证环冷机运行平稳、内部气流、温度等合理分配，确 1。 保球团矿的有效氧化，是搞好环冷机维护的关键。 表1 2013年11月~2014年元月环冷机故障次数统计表 马钢链窑生产线的大修原计划
