摩擦焊接工艺在开发重型系列钎杆中的应用
|
摘要
随着使用液压凿岩钻车的数量越来越多,钻孔向着大孔径、长深度方向发展,对钻孔效率和直线度提出了更高的要求。所需的重型凿岩钎杆正朝着高品质、粗直径、超长度的方向发展。为了满足市场需求,采用摩擦焊接工艺通过理论计算和矿山试验开发出了高品质重型快换钎杆以及提高钻孔直线度的导向钎杆等系列钻具,产品质量接近国外先进水平。
With the increasingly wide application of hydraulic drill wagon for jack hammer,drillholes have become of larger diameter and greater depth,and there have been higher demand for drilling efficiency and straightness,as well as an increasing need for heavy drill rods with higher quality,larger diameter and greater length. In order to meet market demand,we adopted the friction welding technology. Through theoretical calculation and experiments in mines,we developed high-quality quick- change heavy drill rods,guide drill rods which could improve drillhole straightness,etc. The quality of these products approached the advanced world level.
