摘要
铁矿球磨机用ZGMn13Cr2高锰钢衬板在生产使用中有缩孔及裂纹等缺陷,严重影响了使用寿命。分析了缺陷产生的原因,采取了相应工艺优化和质量改进措施,较好地消除上述铸造缺陷,衬板的成品率和使用寿命得到了明显提高,取得了较好的经济效益。
Defects such as shrinkage and cracks often occurred in ZGMn13 Cr2 high manganese steel lining plates for iron ore ball mill, which severely shortened the service life of lining plates. Through analyzing the causes and taking the prevention measures in casting process design, these casting defects were well removed. The finished product rate and service life have been significantly improved and the better economic benefits is also obtained.
