钢棒尺寸控制好,钢棒太长容易出现断棒。
Reply #72018-11-26
楼主 你们钢棒的长度是多少????
Reply #82018-11-27
他们应该是钢棒加长了,与原始要求的不一样
Reply #92019-01-03
钢棒的技术参数不适合磨煤机工况的可能性更大一些
Reply #102019-01-03
还有非常大的可能就是钢棒的提升高度较高,导致落下受力较大
Reply #112019-01-05
这个问题应该不大,提升高度与衬板结构和磨机转速有关,这个一般是固定的,除非买的磨机是不常做棒磨机的厂家生产的,一般中信秋林沈冶都问题不大,估计钢棒应该用的是热轧圆钢硬度HRC20左右的,建议采用调质的硬度HRC45-55.我已经服务了70%的国内煤化工,我可以解决断棒。

后来解决就是降转速,改提升衬板,才让断棒量降了下来
Reply #132019-02-02
断棒较多一般原因都是因为钢棒材质不合适,多考察更换其他材质的钢棒试试。
Reply #142019-05-26
因为一期也是用一样的棒和煤,排除这两方面原因。后来加了变频器降低转速,好多了
Reply #152019-12-18
由此分析来看,是工况问题,而不是磨棒,但是仍建议选择高硬度热处理磨棒。因为转速提高,磨矿效率大,日产能多,棒的耗用肯定比普通圆钢的低很多。
