护坡模具制作工艺特性
Manufacturing Process Characteristics of Slope Protection Mould
1.可锻性
1. Forgetability
具有较低的热锻变形抗力,塑性好,锻造温度范围宽,锻裂冷裂及析出网状碳化物倾向低。
It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, low tendency of cold cracking and precipitation of network carbides.
2.退火工艺性
2. Annealing Processing
球化退火温度范围宽,退火硬度低且波动范围小,球化率高。
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
3.切削加工性
3. Machinability
切削用量大,刀具损耗低,加工表面粗糙度低。
Large cutting parameters, low tool wear, low surface roughness.
4.氧化、脱碳敏感性
4. Sensitivity of oxidation and decarbonization
高温加热时抗氧化怀能好,脱碳速度慢,对加热介质不敏感,产生麻点倾向小。
When heated at high temperature, it has good antioxidant capacity, slow decarbonization speed, insensitive to heating medium and little tendency to produce pitting.
5.淬硬性
5. Hardenability
淬火后具有均匀而高的表面硬度。
After quenching, it has uniform and high surface hardness.
6.淬透性
6. Hardenability
淬火后能获得较深的淬硬层,采用缓和的淬火介质就能淬硬。
After quenching, a deeper hardening layer can be obtained, and it can be hardened by using a mild quenching medium.
7.淬火变形开裂倾向常规淬火体积变化小,形状翘曲、畸变轻微,异常变形倾向低。常规淬火开裂敏感性低,对淬火温度及工件形状不敏感。
7. The cracking tendency of quenching deformation is that the volume change of conventional quenching is small, the shape warpage and distortion are slight, and the tendency of abnormal deformation is low. Conventional quenching has low cracking sensitivity and is insensitive to quenching temperature and workpiece shape.
8.可磨削性
8. Grindability
砂轮相对损耗小,无烧伤极限磨削用量大,对砂轮质量及冷却条件不敏感,不易发生磨伤及磨削裂纹。
The relative wear of grinding wheel is small, the limit grinding amount without burn is large, and it is insensitive to the quality of grinding wheel and cooling conditions, so it is not easy to cause grinding damage and grinding cracks.
