摘　　要：单辊破碎机是烧结矿生产线上一个重要的部件,其工作环境与性质决定其必须具有抗高温与耐磨损的特性。针对目前单辊破碎机易磨损、寿命短的问题,首先,对其失效原因与磨损机理等方面进行了研究,得出其主要磨损形式是高温环境下带有凿削形式磨损的磨粒磨损。然后,研究了其抗磨损结构设计的方法,并对其材料选择与耐磨堆焊工艺等进行了详细分析与探讨,设计了一种抗磨损的长寿命烧结矿单辊破碎机。最后,通过工程实际使用验证了提出的单辊破碎机抗磨损技术是可行且有效的。Sinter single-roll crusher is an important component of the sinter production line,which operating environment and nature decides that it must possess properties of high-temperature resistance and abrasion resistance.First the invalid reasons and abrasive wear mechanism are studied aim at the problems of easy worn and short service life of the single-roll crusher.A conclusion is made that the abrasion pattern is abrasive wear happens under high-temperature environment with forms of chiseling and cutting.Then a structural design with abrasion resistance is studied,simultaneously its materials selection and hardfacing technics are also analyzed and discussed.Afterwards,one single-roll crusher with characteristics of long service life and abrasion resistance is designed.which is proved in the engineering practice that the proposed anti-wear technology for single-roll crusher is viable and effective.
