Importance des barres de forage dans l'industrie

Une barre de forage est un long tube en acier qui est utilisé pour transférer la rotation et le couple du moteur de forage au bit de forage. La barre de forage est généralement conique à une extrémité, ce qui lui permet de se connecter à d'autres barres ou à un bit de forage. Les barres de forage sont disponibles dans une variété de tailles et de configurations, en fonction des exigences spécifiques du projet de forage.

3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.

Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.
