摘　　要：首次提出将螺旋孔型斜轧钢球轧辊的成型区型腔分为两部分进行研究。在型腔封闭部分，设计时仅需考虑满足设计第二原则，第一原则自然满足。在型腔未封闭部分，设计时仅需考虑满足设计第一原则，第二原则不必考虑。从理论上分析，这样设计的孔型有利于型腔中金属的合理流向。轧制实践表明，采用这种孔型能轧制出比前苏联、美国两种孔型更高质量的钢球。It is the first time to propose that the groove of forming area of helical skew roller can be divided into two parts for designing In designing closed groove,the second basic principle of design must be considered The first basic principle of design naturally meet the request.In designing unclosed groove,the first basic principle is exclusively required rather than the second basic principle The type of this groove is more suitable for rational metal flow theoretically and it can be used to roll balls more accurate than that of Russian or American designed
