摘　　要：经过10多年的艰苦探索，我国新一代“新型Cr-Ni-Mo、Cr-Ni-W系列‘穿孔-全程带芯纵轧法’中空钎钢”已经问世。由于其所拥有的技术、资源优势和极具市场竞争力的性价比指标，将为以硬质舍金整钎和重型螺纹连接钎杆为代表的我国长钎具工业走向世界，奠定了坚实的技术和物质基础。The ＂New type series of Cr-Ni-Mo,Cr-Ni-W hollow rock drill steel by ＇hot-penetrating and hot-rolling with core method＇＂have come out after more than 10 years of hard work. In view of advantage in technology and resources, the ratio of properties to price has extreme competent. It may lay a solid technology and material fotmdation for our rock drilling tool industry represented by integral drill steels and extension rods to move towards the world market.
