介绍了粉末冶金软磁材料在制造XC型仪表零件中的应用及其技术经济效果。采用动压、氢气保护烧结、复压工艺,其密度≥7g/cm~3,所制零件完全满足产品装配要求。其经济效果显著,以年产8万台计算,与用DT4纯铁棒加工(材料利用率40％)相比,全年可节约原材料费6万元,节约加工费12万元。粉末冶金软磁材料完全可以在仪表零件制造中推广应用。
The application of powder metallurgy soft magnetic materials in the manufacture of XC instrument parts and their technical and economical effects are introduced. The use of dynamic pressure, hydrogen protection sintering, complex pressure technology, the density ≥ 7g / cm ~ 3, the parts manufactured to fully meet the product assembly requirements. Its economic effect is remarkable. Calculating with an annual output of 80,000 units, it can save raw materials cost 60,000 yuan and save processing cost 120,000 yuan compared with DT4 pure iron bar processing (material utilization rate 40%). Powder metallurgy soft magnetic materials can be widely used in the manufacture of instrument parts.
