为了试用我厂生产的新型硬质合金钎头,我们走过十几个矿务局,调查了解钎头的使用情况和生产情况,多数矿务局都是自产自用,不外购钎头。各局使用的钎头体材质不同,钎头的几何结构参数不统一,硬质合金片的钎焊方法也各有特点。井下掘进工人总的反映是一致的,钎头碎片掉片太多,消耗量很大。各局分散自产自用,受设备条件和选用材料的限制,在短期内很难全面达到新型硬质合金钎头的各项技术指标,但是如果能够
In order to try our factory production of new carbide drill bits, we walked a dozen mining bureau, investigation and understanding of the use of bit conditions and production, most of the mining bureau is for own use, do not outsource the first bit. Buret heads used by the Bureau of different materials, the geometric parameters of the drill head is not uniform, the brazing of carbide films also have their own characteristics. Underground miners generally reflect the same reaction, too much debris off the chip, a lot of consumption. Bureau of dispersed production for personal use, subject to equipment conditions and the selection of materials, in the short term it is difficult to fully meet the new carbide head of the various technical indicators, but if able
