降低终锻温度及冷却速度，使钒的析出量增多，而对钛的析出则影响不大。

To lower the final forging temperature and cooling speed will increase the amount of vanadium precipitation but has no obvious effect on titanium precipitation .

增加累积变形程度并适当降低终锻温度（一般为860～910℃）有利于碳化物破碎及钢材质量的提高。

The increase of the accumulated deformation degree and a reasonable amount decrease of the final deformation temperature ( 860-910 ℃) are favourable for the fineness of carbide .

锻造时控制始锻温度为1150℃，终锻温度为920℃，并按正确工艺退火、调质。

When forging , the beginning forging temperature has been controlled to be 1 150 ℃, and the end forging temperature to be 920 ℃, then according to the correct process the annealing , quenching and tempering has been proceeded as well .

通过对裂纹脱碳情况综合分析以及对锻造过程剖析后，认为该裂纹系锻造过程所致，其原因与原材料表面存在缺陷或坯料形状不规则以及终锻温度过低有关。

It is believed that the cracks are caused by forging process according to the decarbonization analysis and forging process evaluation . The cracks are associated with the surface defect of raw material and irregular shape of billets , and extra low final forging temperature .
