1) quality forging
优质锻件
2) quenched and tempered heavy forging
调质大锻件
1.
This paper measured the cooling curve of quenched and tempered heavy forging in temper cooling, and calculated maximum instantaneous elastic stress in cooling below 400℃.
测量了调质大锻件高温回火冷却时的表面及心部冷却曲线、室温及低温冲击韧性,并且计算了400℃以后冷却时最大瞬时弹性热应力。
2.
In order to investigate the surface residual stress of 40Cr steel quenched and tempered heavy forging after high temperature tempering,relationship between surface residual stress and tempering cooling temperature of mm and mm 40Cr steel specimens was studied by using X-ray stress measurement.
为了解40Cr钢大锻件高温回火后表面残余应力的情况,应用X射线应力分析方法研究了该钢50 mm及170 mm两种试样在高温回火后的表面残余应力与出炉冷却温度的关系,并计算了800 mm调质大锻件在400℃下出炉空冷时的最大热应力。
3) high quality casting
