锤杆受力情况复杂,应力变化剧烈,在工作时容易折断.我厂的一台5t锤每年平均要折断5根锤杆.为了提高锤杆的使用寿命,我们分析了锤杆折断的原因,在材质和热处理工艺两方面着手改进,收到了令人满意的效果.一、分析1.锤杆的材质用35CrMo替代40Cr作为锤杆的材料,不仅使锤杆具备了铬钢的抗蚀性和热稳定性,而且提高了锤杆热强度和降低了热脆的敏感性.2.锤杆的热处理
Hammer rod force situation is complicated, the stress changes drastically, easily broken at work.A 5t hammer of our plant averagely breaks 5 hammer rods every year.In order to improve the service life of the hammer rod, we analyzed the reason of hammer rod breakage, In the material and heat treatment process to improve both, received satisfactory results.A analysis 1. Hammer rod material used as a replacement for 40Cr hammer rod material 35CrMo, not only to make the hammer rod with chromium steel corrosion resistance and Thermal stability, but also improve the hot rod strength and reduce the sensitivity of the hot brittle .2 hammer rod heat treatment
