摘　　要：针对整体铸造的球团齿辊使用寿命低和易渗漏的问题,研制开发了一种三段式结构的生产工艺。通过选择合适的材质,设计合理的铸件结构、芯盒结构及浇注系统,以及热处理工艺,并借助铸造仿真凝固模拟,加强各工序质量控制,解决了齿辊打压漏水及使用寿命短的难题。实践证明,生产的齿辊耐磨性能好,使用寿命长。The service life of integral casting toothed roll is short and the leakage occurs easily. To solve these problems, a three-stage structure production technology was designed. By selecting suitable material, designing sound casting structure, core box structure and gating system, and adopting reasonable heat treatment process, the problems of leakage and short service life were solved by means of solidification simulation, which can strengthen the quality control of every working step. The experience indicates that the wear resistance and service life of toothed roll were improved.
