系统分析了轧环机轧辊尺寸对咬入条件、锻透条件、环件刚性条件、环件最大初始壁厚以及设备能力的影响。在综合考虑各种因素的基础上提出了轧环机轧辊设计准则，对环件轧制工艺设计有指导意义。 The influences of roll size on the conditions of bite, the conditions of forging penetration, the rigidity of the ring, the maximum initial wall thickness of the ring and the capacity of the equipment were systematically analyzed. Based on the comprehensive consideration of all kinds of factors, the design rule of rolling ring roller is put forward, which is of guiding significance to the design of ring rolling process.
