IGZR-1数控等离子螺旋钻杆粉末堆焊机 ■ IGZR-1 CNC Plasma Spiral Drill Pipe Powder Surfacing Machine
Deep hole drilling technology is one of the key technologies for gas drainage in coal mines. The drilling speed and hole formation length determine the scope and efficiency of gas drainage. Due to the different conditions of coal seam occurrence in different regions, the difficulty of deep-hole drilling varies greatly. Soft and outburst coal seams account for a large proportion (40%) of China's recoverable coal seams. Drilling in such coal seams, especially in areas with high geostress, has slow drilling speeds, low porosity, shallow pores, and It is easy to jam, lose or even cause coal seam fire due to overheating. Drilling in soft and outburst coal seams has always been one of the difficult problems of drilling technology at home and abroad.
In order to solve this kind of problems, experts, scholars and field technicians have been working hard to explore and try some ways to manage the collapse of holes. For example, in smooth drill pipe drilling, wind or hydraulic slag removal methods, spiral grooves are processed on the surface of the drill pipe or steel bars are wound and welded on the surface of the drill pipe to form spiral ridges. When drilling holes, the coal dust clinging to the drill pipe is pulled out by the assisting force of the spiral to dredge (wind or water) the main chip removal channel, so that drilling can continue. However, the above two methods have different defects. One is that the method of processing the spiral groove on the surface of the drill pipe reduces the cross-sectional area of the drill pipe, generates stress concentration, and the drill pipe is more easily broken. The winding welding method is one of low manufacturing efficiency and high cost, and the other is that the wound steel bars are mostly ordinary carbon steel, and the spiral ribs are quickly worn away during the drilling process.
After continuous theoretical research and scientific experiments, Aigang Co., Ltd. and Shanxi Lu'an Group have successfully developed "Plasma Beam Cylindrical Surface Fine Surfacing Technology" and "IGRF CNC Plasma Spiral Drill Rod Powder Surfacing Welding Machine". And produced "new-type slag-removal anti-seizure wear-resistant spiral drill pipe." The wear-resistant spiral on the drill rod is made by surfacing welding of alloy ceramic powder on the drill rod by means of the energy of the plasma beam. The combination of the spiral and the drill rod is completely metallurgical, so the spiral surfacing layer is not only wear-resistant It is also impact resistant, and its abrasion resistance is indeed 4 to 5 times that of the drill pipe itself (R780 special pipe for drill pipe). The successful application of the “plasma beam current cylindrical surface fine surfacing technology” in the gas drainage drill pipe broke through the technical bottleneck restricting the difficulty in drilling in soft and outburst coal seams, increased the drilling speed and the length of the hole, and reduced stuck , Lost drilling, and coal seam combustion have improved the level of gas management, and its economic and social benefits are very significant.
