采用上海新跃仪表厂自行研制的刚玉流动粒子炉对三种新型模具钢进行了过饱和渗碳工艺的研究。结果表明:适当控制氮气与丙烷的比例可以获得良好的渗层组织及很高的表面硬度;刚玉流动粒子炉渗碳能够获得较高的渗碳速度。
Shanghai New Yue Instrument Factory developed by the corundum mobile particle furnace on the three new die steel was saturated with carburizing process. The results show that proper nitriding and propane ratio can achieve good infiltrated microstructure and high surface hardness. Corundum flow particle furnace carburizing can achieve higher carburizing rate.
