T45 T51 Gt60 Speed Mf Drill Rod with Length 3.66m Rod Drill
The round cross sections are more prevalent for extension drilling applications. A round rod has less material and thus is lighter to handle and less expensive than an equivalent size hexagonal rod. While hexagonal rod is particularly advantageous for drifting and tunneling drilling. The increased rigidity of hexagonal drill rods enables them to abating hole-deviation and enhances flushing for cleaning holes. Even with the larger cross section, hexagonal steel can still accommodate the same diameter bit as that of an equivalent round steel.
M/F rods provides tighter connections and is easier for handling and quicker for uncoupling than M/M rods, and are potential to drill straighter holes.
Carburization technique is mainly used in the production of big diameter rods to ensure excellent performance. Carburizing is for hardening entire rod to provide an external over entire rod surface area. Carburized steels are used primarily in underground applications and where water is used as a flushing medium. High Frequency technique is primarily used in the production of small diameter rods to reduce fragileness of drill steels. High Frequency is for hardening only the thread ends of the rod. This provides the longevity of the product as well as being more suitable for more drilling condition need. Steels produced with this technics primarily used in surface drilling applications where air is the primary flushing medium. Phosphorising is to improve anti-erosion capability of the entire external rod surface area.

rocessing Customized Rock Bolt Coal Mine Roof Tunnel Support Anchor Rod Mining Hollow Anchor Rods
It is mainly used for systematic support of surrounding rock with medium and good geological conditions.
In the case of hard rock,horizontal bedding of rock strata, open joint fissures with mud or groundwater development, steel expansion shell bolts can be used to quickly form initial support, control the deformation of surrounding rock, ensure the stability of surrounding rock, and then grouting and permanent anchoring.
After drilling the hole with a rock drill to the designed depth of the anchor rod, install the steel anchor head on the anchor rod body and put it into the hole.
After installing the grout stopper, backing plate and nut,reverse the anchor rod to make the expansion shell anchor head expand to catch the hole wall, and then conduct grouting.
