针对Cr12MoV钢轧辊感应淬火易开裂及硬化层深度的问题,研究了预热温度、淬火加热温度、感应圈移动速度和电源频率对Cr12MoV钢轧辊的硬度、开裂和硬化层深度的影响,探索了Cr12MoV钢轧辊具备高硬度不开裂及厚硬化层的方法。结果表明, Cr12MoV钢轧辊调质态硬度低于32 HRC与预热温度高于450 ℃时,能避免淬火开裂;随着感应淬火温度或感应圈移动速度提高,淬火Cr12MoV钢轧辊硬度出现先升高后降低的趋势,但无法明显影响硬化层深度;而随着感应电源频率降低,淬火Cr12MoV钢轧辊硬化层深度明显增加,但对淬火件硬度影响较小。

In view of the problem of Cr12 MoV steel roll cracking easily and hardened layer depth during induction hardening, the effects of preheating temperature, quenching heating temperature, induction coil moving speed and power frequency on hardness, cracking and hardened layer depth of the Cr12 MoV steel roll were studied, and the method of Cr12 MoV steel roll with high hardness without cracking and thick hardened layer was explored. The results show that when the quenched and tempered hardness of the Cr12 MoV steel roll is lower than 32 HRC and th...
