摘　　要：采用扫描电镜等方法对钢铁厂破碎焦炭的四辊破碎机破碎辊进行了磨损失效分析,结果表明,破碎辊失效的主要原因是切削磨损和疲劳磨损,高强韧性的耐磨铸钢适用做破碎辊。The wear failure of rollers in 4-roller crusher in iron and steel plant was analysed with SEM. The results show that cutting and fatigue wear are the main reasons causing the rollers to fail. Wear resistant cast steel with high strength and toughness is suitable for rollers.
