Gear quenching and tempering process description (Cement mill large gear ring as an example)

The gear quenching and tempering process is described below for reference.

After roughinggearFor quenching and tempering, it is best to reduce the machining allowance of the tooth surface as much as possible, so as to ensure the hardness after finishing.

以1400kW水泥磨大齿圈举例，制定调质工艺。大齿圈尺寸为(φ2378-φ1970)×858mm，要求调质硬度为300-340HBS。其热处理工艺曲线如图，产品的硬度符合要求。

The above is the description of the gear tempering processing technology, including but not limited to, if you have any unclear points or related requirements, you can consult EP for free.
