边沟盖板模具材料选择
Material selection for side groove cover mold
堤坝护坡模具选材是整个模具制作过程中非常重要的一个环节。
The material selection of the embankment slope protection mold is a very important part of the whole die making process.
堤坝护坡模具选材需要满足三个原则：（一）模具满足1、耐磨性2．强韧性3．疲劳断裂性能4．高温性能5．耐冷热疲劳性能6．耐蚀性等工作需求；（二）模具满足1．可锻性2．退火工艺性3．切削加工性4．氧化、脱碳敏感性5．淬硬性6．淬透性7．淬火变形开裂倾向8．可磨削性等工艺要求；同时模具应满足经济适用性。
Three principles should be met in the selection of moulds for embankment slope protection: (1) the moulds meet the requirements of 1, wear resistance 2, strength and toughness 3, fatigue fracture 4, high temperature 5, cold and hot fatigue resistance 6, corrosion resistance, etc. (2) the moulds meet the requirements of 1, malleability 2, annealing process 3, cutting workability 4, oxidation and decarbonization sensitivity 5, quenching Hardness 6. Hardenability 7. Quenching deformation and cracking tendency 8. Grindability and other technological requirements, and the mold should meet the economic applicability.
