Heat Treatment 

热加工

加热温度1170-1190℃,开始温度1120-1150℃,终止温度≥850℃,热加工后在600-850℃区间应快冷,以免沿晶界析出碳化物,在≤600℃缓冷。

Hot working specification

The heating temperature is 1170-1190 ℃, the starting temperature is 1120-1150 ℃, and the ending temperature is ≥ 850 ℃. After hot processing, it should be cooled quickly in the range of 600-850 ℃, so as to avoid carbide precipitation along the grain boundary and slow cooling at ≤ 600 ℃.

球化退火

退火温度(870±10)℃,保温3h,降温到(730±10)℃,保温4h,炉冷到≤500℃,出炉空冷。球化退火温度后硬度200HBW,球化组织为2级。

Spheroidizing annealing

Annealing temperature (870 ± 10) ℃, holding for 3h, cooling to (730 ± 10) ℃, holding for 4h, furnace cooling to ≤ 500 ℃, discharging air cooling. After spheroidizing annealing temperature, the hardness is 200hbw, and the spheroidizing structure is grade 2.

淬火、回火

预热温度500℃,保温2h,第二次预热温度860℃,保温2h,升至淬火温度(1140±10)℃,保温30min,油冷至180-200℃,出油空冷,600-610℃×2h空冷回火两次。

Quenching and tempering

Preheating temperature: 500 ℃, holding for 2h, second preheating temperature: 860 ℃, holding for 2h, rising to quenching temperature (1140 ± 10) ℃, holding for 30min, oil cooling to 180-200 ℃, oil outlet air cooling, 600-610 ℃ × 2H air cooling tempering twice.
