摘　　要：经过10多年的艰苦探索,我国新一代“超纯、超细、窄带Cr-Ni-W-Mo-V系列‘穿孔—全程带芯纵轧法’中空钎钢”即将问世。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,将为以硬质合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 ″Super-pure, superfine and limited hardness in scope Cr-Ni-W-Mo-V 'hot-penetrating and hot-rolling with core method' hollow rock drill steel″ will soon be come out after more than 10 years hard work. In view of have an advantage in technology and resources, the ratio of properties and price has extreme competition. It mast be lay a solid foundation on technology and material for our rock drilling tools industry represent by integral drill steels and extension rods to move towards the world.
