Rotary drilling rig undercarriage parts track link

Track link assy is a large, oblong-shaped chain link made from high-grade alloy steel, which is suitable for rotary drilling rig. The track chain rail is connected with the track shoe through bolts and nuts to form a track assembly, which bears the pressure of the whole rotary drilling rig machine and is an important walking part of the undercarriage, so the quality of the chain is very important.

2. Advanced processing machine

Our company has 1600T and 2500T two hot die forging production line. The size of track chain produced by hot die forging press equipment is stable.

The mesh belt furnace automatic equipment is adopted. The internal structure of the product tempered by mesh belt furnace is even, the quality of batch production is stable, and the problem of hardness is avoided.

From material extraction, melting, cooling, quenching, shaping, tempering, forming, and scene testing, Yantai Orient's track link has undergone multiple rounds of grinding and forging.

3. Strict quality control

Each batch of raw material is subjected to physical and chemical experiments.

Each bar's heating temperature is strictly controlled.

Each batch of heat treatment is performed Metallographic analysis.

Every track link has been inspected to avoid any defects.

Every track link has a code that can be traced.
