In the core link of the fuel handling system of thermal power plants, the shift plate has long been subjected to severe erosion and wear from materials such as coal blocks and ores, becoming a bottleneck restricting the continuous operation and maintenance costs of the equipment. As a key component for fuel transportation and distribution, the shift plate works in an extremely harsh environment and is exposed to the impact of high-speed, highly abrasive materials for a long time. Traditional materials or single protective measures are often unable to cope with this, resulting in frequent severe wear, deformation, and even failure of the shift plate. This not only forces power plants to increase the number of unplanned shutdowns for replacement and maintenance, pushing up spare parts procurement and labor costs, but also directly threatens the stable operation of the fuel supply system and affects power generation efficiency.
The problem of stubborn wear of the feed plate that has hampered production, our company has successfully developed an innovative "dual-core wear-resistant strengthening technology" for our customers. Through the synergistic effect of mechanical reinforcement with tungsten carbide studs and high-performance cladding wear-resistant welding wire coating, we have built an unprecedented solid defense line for the feed plate of the power plant, significantly improving its service life and system reliability.

2. Precision coating of wear-resistant welding wire:
On top of the reinforced skeleton formed by tungsten carbide studs, advanced automated equipment is used to precisely weld multiple layers of high-performance wear-resistant welding wire (high chromium composite). The metallurgical bonding coating formed by this process has extremely high hardness (HRC can reach more than 60) and excellent abrasive wear resistance, becoming the first and most important barrier to resist micro-cutting wear of materials. The optimization of welding wire composition and process ensures that the coating has both excellent wear resistance and good impact toughness.

These two technologies are not simply superimposed, but form a deep synergistic effect of "pinning to resist impact, cladding to resist wear". The tungsten carbide studs effectively disperse and absorb high-stress impact energy and protect the cladding layer; while the dense and tough cladding layer maximizes the elimination of material wear on the substrate. This "rigid and flexible" structure has made a qualitative leap in the overall wear resistance of the material stripper plate.
Final welding effect:
According to actual application tests and customer feedback, the power plant feeder plates processed with this dual-core strengthening technology have: significantly extended service life: compared with traditional treatment methods or ordinary material feeder plates, the service life is generally increased by more than 150%, and can even reach 3 times under some working conditions; maintenance costs are greatly reduced , the frequency of spare parts replacement is drastically reduced, and downtime maintenance time is shortened, which significantly reduces the overall cost of power plant operation and maintenance; operational reliability is enhanced: effectively reducing the risk of unplanned downtime caused by sudden wear and failure of the feeder plate, ensuring the continuous and stable operation of the fuel supply system, and improving power generation efficiency.
