    Heat treatment

    1.Quenching with fire about 860 °C, placed in furnace box

    2. After quenching, put into the oil tank to cool from the box furnace

    3. After cooling, the first time tempering: tempered at 640 °C and the hardness is controlled at about HRC28-32, the first time tempering cooling is used Water-cooled.

    4. Straightening: The outer circle is controlled by 200 um(0.2mm) ;

    straightening equipment:

    three-roller straightening machine;

    hydraulic straightening machine (multipoint straightening)

    5. The second tempering removes the hard force, the temperature is about 480 °C, and Keep warm for 2 -2.5hours ; release 80% more or less
