Sansung rock drilling extension rod are created with high high quality of alloy steel bar and tungsten carbides with exceptional wear resistance and effect toughness superior, by means of heat therapy so that it can stand up to the toughe EPT rock drilling requires, and transmit intensive effect energy into the rock with the lea EPT attainable reduction of power. They are extensively utilized in all types of mining, drilling, quarrying, engineering, building, drinking water nicely drilling, oil checking out industries and so forth.
Extension rod:
EPT names are Extension drill metal, Extension drill rod, and Extension metal, M/Frod (Speed rod), produce Hexagonal and round cross-sections,Hexagonal rods are more rigid, heavier and transfer vitality a lot more successfully,whilst escalating flushing. Round rods are usually lighter than hexagonal rodsand are typically used in extension drilling programs. With the lengthier steel tending to be bigger in diameter, conventional extension steel is characterizedby replicate thread on every end of the steel.
Extension rods are created by hollow drill steels, various lengths are accessible from 600mm to 6400mm. This hollow hole are usually named flushing hole, utilized for transmitting drinking water or air in the course of drilling. And the threads can be employed for connecting couplings, shanks adapters or bits.
Male/Woman (M/F) rod, speed rod:
M/F drill steel is an substitute to couplings sleeves to consist of the feminine component of the threaded link as an integral part of the drill steel. M/F drill metal supplies much more rigid connections and is simpler to uncouple and deal with. The provider life also tends to be better than with different couplings. The advantages of drilling with M/F metal consist of: simple managing, a lot quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service lifestyle.
For extension rod and M/F metal method, the beneath two distinct sorts of heat therapy are employed to reinforce substantial velocity and effective percussive drill string components to increase their efficiency and reliability. For a longer time metal larger in diameter, traditional extension steel, Hexagonal and spherical cross sections are available.
Carburizationis a approach utilized to harder the whole rod area equally internally and externally to strengthen and increase the existence of the rod.
High frequency induction is process where only the thread ends of the rod are hardened to lengthen thread existence.
