超穿深石油射孔弹粉末冶金药型罩的研制

Ultra-deep Oil Through Perforated Shells Development of Powder Liner

介绍了一种特殊石油射孔弹药型罩,通过在粉末冶金材料配方选择、冷压成型、高温烧结、多次整形等工序,应用了我国传统的粉末药性罩制造工艺,达到了无堵杵、高穿深(1500mm)等性能指标,超过了国外同类产品的穿深指标。

This paper introduces a special perforation ammunition liner,through the formula in powder metallurgy materials selection,cold forming,high temperature sintering,plastic and so many times,the application of traditional herbal powder mask manufacturing process,to the non-blocking pestle high penetration depth（1500MM） and other performance indicators,more than similar foreign products penetration indicators.
