摘　　要：用铌钼镍合金化铸态法,直接获得针状组织(贝氏体)球铁轧辊,这种材质辊身截面硬度落差小,并具有较好的强韧性,耐磨性、抗热疲劳性。在同等条件下的使用寿命,是镍铬钼(1)无限冷硬轧辊的3.7倍。The acicular constiuent (bainite)ball -Iron roll Can be manufactared directly by as Nb - Mo -Ni alloy Cast condition. This roll has small falling head on section hardness and good indomitable and firm ability,wear resistance and beat resistant fatigue. Its using life is 3. 7 times of Ni-Cr - Mo (I) infinite chill roll under the same condition
