Rock drilling rig drill pipe-beneficial mining technology.
The six-party drill rod is widely used in rock drilling and blasting in mining, metallurgy, transportation, water conservancy and hydropower projects. Material selection of Shanghai Baosteel 23 CrNi3Mo, the overall vacuum conditioning treatment, thread processing using advanced imported CNC lathe, greatly improving the drill rod fatigue strength and impact. It can be used with well-known rock drilling jumbo such as Atlas, Porter, Guhe, Gordon Denver, Ingersoll Rand, Montabert, etc. With reasonable matching, the continuous service life of drill pipe can reach about 3000 meters. Parameters Drill Rod Length Outer Diameter Weight Benefiting Mine Model R32-Round32-R32 mm

Application of down-the-hole drill pipe-Yikuang Technology
It is mainly used in rock drilling and crushing, anchoring drilling, geothermal air conditioning hole, water well drilling, etc. The pipe body is made of materials produced by well-known large-scale iron and steel enterprises in China. The two ends of the pipe body are internally thickened, tempered after friction welding, quenched and tempered after rough machining of drill pipe joints, and nitrided after surface finishing. The failure rates such as gluing, broken buckles, outer diameter expansion and cracking are effectively eliminated, and the pipe body is more wear-resistant and easy to disassemble. All imported precision CNC lathes and custom-made forming knives are used for thread processing. All threads are equipped with thread gauges in line with international standards, so the quality of the drill pipes produced is stable and reliable.

Application of compressed air slag discharge cooling drill bit-Yikuang Science and Technology
At present, in the drilling of coal mine gas drainage construction, due to the geological conditions and technological requirements of the coal mine, water or air injection is injected during the drilling process to achieve the purpose of cooling the drill bit, so as to prevent the high temperature caused by high-speed rotation friction from causing the composite sheet to wear and fall off. During the implementation of water injection drilling, due to the change of water volume and the different softness of formation rocks, holes are often blocked due to the development and expansion of rocks exposed to water. Moreover, when water injection drilling is carried out at negative angle and vertical drilling, drill sticking is often caused by poor anti-slag effect. When drilling is stopped midway, drill pipes are locked due to rock cuttings solidifying in water. Therefore, water injection drilling is not suitable for compound in many cases.
