凿岩钎具用硬质合金产品市场趋势分析

Analyses of Trends in Market for Carbide Products for Rock Drilling Tools

介绍了使用硬质合金的凿岩钎具类型,并对我国凿岩钎(钻)具使用的硬质合金种类和需求数量作了分析。钨资源是目前世界性的紧缺稀有资源之一,而凿岩用硬质合金产品又是碳化钨硬质合金中使用量较大,消耗较快的产品。我国是世界上主要钨资源生产国,同时也是碳化钨制品消费大国,正确了解凿岩用硬质合金的使用性能,掌握各种不同类型凿岩钎(钻)具对硬质合金的要求,进一步提高我国凿岩硬质合金的质量,将对我国钨资源的合理利用有着重要的意义。

the paper describes types of rock drilling tools which use carbide and analyzes the types and quantities of carbide used on rock drilling （boring） tools in China. It concludes that tungsten is one of scarce resources worldwide today and carbides for rock drilling tools are of high consumption and short life cycle among tungsten carbides. China is a leading manufacturing country for tungsten resource in the world, as well as a large consuming country of tungsten carbide products. It will have a fundamental significance on the reasonable use of China＇ s tungsten resource to have a proper grip on the usage properties of carbide for rock drilling tools, understand various rock drilling （boring） tools＇ requirements on carbides, and further improve the quality of carbide for rock drilling tools.
