Cold rolls made of forged steel MC3 and MC5 with higher alloy contents have been successfully developed through using some special technolo- gies to control the alloy steel's inclusions,gas content,porosity and segregation,especially adopting a main measure like"forging in core-anvil".
通过采用独特的冶炼工艺控制钢中的夹杂物、气体含量、疏松、偏析等内在冶金质量,并采用型砧锻造等主要措施,成功实现了真空精炼工艺制造MC3,MC5合金含量较高的锻钢冷轧辊,各项性能指标均可达到标准要求。
The forging method with horizontal V-shaped anvil are used to control fibrous tissue flow direction, to improve the anisotropy of mechanical properties of axial forgings, to realize uniform forging, resulting in the unique effects that conventional forging methods can not .
本文利用水平V型砧锻造法,企图通过有效控制锻件的纤维流向,改善轴类锻件力学性能的异向性,实现轴类锻件的等向锻造,创造普通锻造法无法达到的特殊锻造效果。
