求翻译：在这个时候需要控制的就是加热的温度，一般要将轴承加热至 80℃，最高到100℃ 就足够了。超过 120℃ 就可能会导致轴承发生回火的现象，从而使套圈的硬度与精度的降低。是什么意思？

At this time is needed to control the heating temperature in the bearings, and a general need to be heated up to the maximum 100 C 80 ° °C would be enough. More than 120 °C bearings can lead to a flash-back, and thus enable the hardness with precision the lower.

In needs to control at this time is the heating temperature, had the bearing heating to 80℃, to 100℃ to be high enough generally.Surpasses 120℃ possibly can cause the bearing to have the tempering phenomenon, thus causes the ferrule degree of hardness and precision depression.
