摘要
通过化学成分分析、金相分析、晶粒度测试等方法,对球磨机滚筒焊缝开裂原因进行了研究。试验方法及思路为类似的失效分析提供参考。结果表明焊剂与焊丝不匹配、母材组织不均匀,是焊缝开裂的原因。
The reasons for weld cracking of ball mill roller were researched by chemical composition testing, metallurgical analysis, grain size testing and so on. The results show that the mismatching between flux and wire and the asymmetry of the base metal were the cause of weld cracking.
