摘　　要：烧结机尾部的单辊破碎机齿冠使用寿命过短是制约烧结工艺的技术难题之一。由于工作环境恶劣破碎机齿冠平均使用寿命不到5个月。通过分析齿冠受力情况、失效特征及影响高铬铸铁抗磨性能的各方面原因，提出了优化辊齿结构和改进齿形的方法，实施后提高了破碎机齿辊使用寿命。The tooth crown of the single-roll crusher at the end of the sintering machine has a very short service life. It is one of the technical difficulties to restrict the sintering process. Owing to poor working conditions, the tooth crown has less than 5 months in average of service life. By analyzing the tooth crown load, failure effect and the factor affecting the wear resistance of high chromium cast iron, it puts forward the roll tooth structure optimization and tooth profile improvement to prolong the service life of the tooth crown.
