摘要
华夏(咸宁)、金龙(武穴)、东湖(武汉)三十凿岩机具公司生产的《青龙》、《金龙》、《飞龙》牌硬质合金整体钎子,是我国1987年正式投放市场的最新式凿岩钎具产品。它广泛用于内燃、电动、气动、液压凿岩机冲击式凿岩。其头部直径为24～50mm,六角杆体内切圆直径为B19、B22、B25、B28、B32mm,有效长度400～6000mm。岩石性质和穿孔方向不受限制。该系列产品体现了现代小直径硬质合金钎具技术的最新成就,社会、经济效益显著,在国内外采掘工业部门拥有巨大市场。推广使用硬质合金整体钎子,将导致我国小直径钎具的第三次升级换代,有力地促进采掘工业的技术进步。
QINGLONG', 'JINLONG ', 'PEILONG' brand cemented tungsten carbide integral drill rods made in the Huaxia ( Xianning) , Jinlong (Wuxue ) , Donghu ( Wuhan ) Rock Drill and Tool Companies, first time put on the market in quantity as the newest product of rock drilling rod in 1987, are widely used in internal-combustion, motor driven, pneumatic, hydraulic rock drill machine to drill rock with lashing way. Of integral drill rods, the bit has the size from 24 to 50mm in diameter, the turret shank diameter has B19, B22, B25, B28 and B32mm, the effective length has 400 to 6000mm. The character of rock and the direction of hole are not limited. This series products reflect the newest achieve-ment of minor diameter cemented tungsten carbide drill rod technology, with re-markable social and economic benefit, and have tremendous market of excavating industry field both at home and abroad. To popularize using the integral drill rods will result in third time renewal and change of the minor diameter drill rod in China, and strongly promote the progress of technique in excavating industry.
