High Performance Extension Rod Top Hammer Drilling Tools Wear Resistance

 
Product description
 
In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The percussive system strikes the drill rod, for example 2,000-5,000 strikes per minute, and the rotation speed can be, for example, 60-200 rounds per minute. Together these elements make it possible to drill holes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction and quarrying of rock material. Top hammer drilling, combined with the “drill and blast” method, makes the whole excavation process extremely efficient.

Advantage
*Material are developed by cooperated with National & Local Joint Engineering Laboratory for High-performance Metal Structure Materials and Advanced Manufacturing Technology to improve the fatigue resistance of drilling steel.
*Material is from Baosteel with strict process of steel smelting and rolling: Refining - Vacuum - Continuous casting - drilling hole method - surface peeling to control the content of non metallic inclusion and harmful element.
*Strictly control precision thread process to avoid thread too hot and broken effected by the high vibration and shaking of thread part when it works.
*Heat treatment: Fully Carburization - Air cool quenching - tempering. It make the rod keep high toughness and improve surface harness and whole strength as well.
*Thread strengthen: enhance the thread parts to improve the wear-resistance and longevity of the rod.
