摘要
冲击疲劳落球试验和冲击磨损试验结果表明，研制的铸态去应力处理的高铬硅耐磨铸铁抗冲击疲劳剥落和抗冲击磨料磨损性能优于马氏体Ｃｒ１５耐磨铸铁；且高铬硅耐磨铸铁断面硬度均匀、生产成本较低。高铬硅耐磨铸铁适宜于制造球磨机磨球。
The results of the ball-dropping impact-fatigue test and impact abrasiveness test showed that the impact-fatigue exfoliation resistance and anti-abrasiveness property of the developed as-cast and stress-relieving treated high chromium-silicon wear-resistant cast iron were better than the Cr15 martensite wearresistant cast Iron.Inaddition, the high chromium-silicon cast iron has more uniform hardness distribution throughout the sections and lower production cost.The high chromium-silicon wear-resistant cast iron issuitable to be used for making grinding balls of ball grinding mill.
