Advantages and Applications of Post‑Processing Techniques for Alloy Column Tooth Surfaces

I. During drilling in highly hard (rock hardness coefficient F14–16) and highly abrasive formations, the carbide teeth of down-the-hole drill bits are subjected to intense impact and cutting‑friction against the tough rock. Conventional manufacturing processes often result in carbide teeth with poor surface stress states, insufficient surface densification, and reduced toughness. Under sustained loading, microcracks propagate rapidly, leading to premature failure modes such as tooth chipping, fracture, and excessive wear, ultimately rendering the drill bit unusable. Frequent replacement of drill bits not only significantly increases mining consumables costs but also severely disrupts continuous production operations.

Introduction and Applications of Tunneling Drill Rods

Rock‑drilling tools include drill bits, drill rods, and drill shanks, and are used to bore blast holes in rock. The drill rod serves as the link between the drill shank and the drill bit, transmitting the impact energy and rotational torque required for rock drilling.

As solid as a shield, operating with peak efficiency: A “hardcore” solution for repairing the roll surfaces of high-pressure roller mills.

In the fields of bulk material comminution and mineral processing, the high-pressure grinding roll (HPGR) is undoubtedly the “heart” of enhancing material‑crushing efficiency. However, when dealing with highly hard, strongly abrasive ores, the severe wear of the roll‑face liners has long been a persistent technical challenge for major mining companies. Frequent shutdowns for maintenance not only erode production profitability but also drive up operating costs.
