摘　　要：在无缝钢管的生产过程中,定尺管的锯切是通过圆锯机以及配套的硬质合金齿圆锯片来完成,因此圆锯机是无缝钢管生产线上重要的设备。在锯切成排放置的钢管时,锯片的上的硬质合金锯齿承受着各种冲击、挤压作用,经常会造成锯齿异常损伤,不仅增加了钢管的锯切成本,同时影响了生产效率。本文根据现场经验,汇总整理了硬质合金锯齿的几种常见损坏形式,分析了损坏产生的主要原因,提出了一些改善建议,可以为客户改善锯片的使用寿命提供有益的借鉴。In the production process of seamless steel pipe,the sawing of fixed length pipe is completed by circular saw machine and supporting cemented carbide saw-tooth circular saw blade,therefore,circular saw machine is an important equipment in seamless steel pipe production line.When saw cutting steel pipes placed in rows,the cemented carbide saw-tooth on the saw blade will withstand all kinds of impact and extrusion function,that often causes abnormal saw-tooth damage,which not only increases the sawing cost of steel pipe,but also affects the production efficiency.In this paper,according to the field experience,summarized and sorted several common damage forms of cemented carbide saw-tooth,analyzed the main causes of damage,and put forward some improvement suggestions,which can provide useful reference for customers to improve the service life of saw blade.
