Analysis of Cracking of Centrifugally-cast Large-sized Composite Sizing Roll

  • 摘要: 从结构设计、生产特点和离心铸造过程等方面,对离心铸造大直径复合定径辊的开裂原因进行了分析,同时应用磁测法对离心铸造过程中产生的应力及其分布情况进行检测。根据分析结果,通过改善结构设计、规范操作过程和控制球化孕育质量,提高定径辊的内层强度,降低铸造应力,以解决该定径辊的开裂问题。
    Abstract: The causes for cracking of the large-sized centri fugally-cast composite sizing roll are analyzed, involving such factors as structure design, production characteristics and centrifugal casting process, etc. And the stress as resulting from the centrifugal casting process and the distribution thereof are measured with the magnetic measurement method. Based on the analysis result, it is proposed to solve the cracking problem of the said sizing roll by means of improving structure design of the roll, regulating the roll operation procedure, control quality of spheroidization and inoculation, enhancing the roll inner layer strength, and reducing casting stress.
