Key factors affecting the service life of CCO Wear Plate

In high-wear industries such as mining, steel smelting, cement manufacturing, and energy, CCO Wear Plate (cladding composite wear-resistant plate) is widely used in hoppers, conveying pipelines, liners, and other parts to resist strong wear and impact. Although CCO wear-resistant plates have excellent wear resistance, their actual service life is affected by a variety of external and internal factors.

The impact of environmental factors on the life of wear-resistant plates

1. The nature of the wear medium

The hardness and shape of the wear medium directly determine the wear rate of the wear plate. In a working environment containing sharp particles such as high-hardness ores, sand, and gravel, the scouring and cutting action of the plate is enhanced, and the life is usually shortened to 6-12 months.

2. High or low working temperature

Temperature changes will affect the hardness and structural stability of the wear-resistant layer. In high-temperature scenarios such as steel smelting (above 450℃), the plate may have problems such as softening of the structure and expansion of microcracks, resulting in a shortened life of 1-2 years.

3. Chemical corrosion environment

If the equipment is in a highly corrosive environment, such as acid and alkali liquids, salt spray, or chemical gases, the CCO wear-resistant plate will cause delamination and peeling due to corrosion, and in severe cases, it needs to be replaced within a few months. In contrast, the service life of plates in non-corrosive environments can be significantly improved.

The influence of the welding process and materials on service life

1. The advantages and disadvantages of welding technology

High-quality welding technology can significantly improve the density and bonding strength of the wear-resistant layer. Automatic gas shielded welding technology has obvious advantages in controlling the weld morphology and reducing thermal deformation, and is more uniform and consistent than manual welding. Studies have shown that the service life of hardfacing wear plates manufactured using advanced welding processes can be extended by 20%-50%.

2. Selection of welding materials

The different composition of wear plate material will directly affect the performance. Welding materials with high-hardness alloy elements such as chromium carbide (Cr) and tungsten carbide (W) can effectively enhance the wear resistance and impact resistance of the plate. Compared with ordinary surfacing materials, wear-resistant composite steel plates made of high-performance alloys can increase the service life by 1.5 to 3 times, especially suitable for extreme wear environments.

The influence of use and maintenance on the length of life

1. Reasonable control of load conditions

Under high load and frequent impact conditions, wear-resistant plates are prone to fatigue cracks due to stress concentration, which accelerates failure. The plate loss rate can be significantly slowed down by adjusting the operating speed and balancing the load distribution. For example, when transporting coal or ore, taking measures such as graded unloading and buffering treatment can help reduce the amount of wear per unit time.

2. Regular maintenance and inspection

Appropriate maintenance measures are essential to extend the life of the CCO Wear Plate. Regularly checking the quality of welds, removing accumulated materials, and repairing slightly peeled areas can effectively prevent small problems from turning into serious damage. Practice has proved that a good operation and maintenance system can add 1-2 years of service life to the wear-resistant plate.
