Draghead Wear Blocks

As core anti-wear protective components for industrial equipment, the draghead wear blocks are manufactured using high-performance materials such as high-chrome alloy, high-manganese steel, tungsten carbide composite, alumina ceramic, and ultra-high molecular weight polyethylene (UHMWPE). They are precision-crafted through advanced processes including vacuum smelting, directional crystallization, high-temperature sintering, cryogenic treatment, and precision machining. The products feature a structural design that achieves "extreme surface wear resistance with a tough, energy-absorbing core." They are specifically engineered for high-impact, high-erosion, and heavy-friction operating conditions, ensuring they do not crack, spall, or deform in harsh environments.

Features:

Key Performance Features
Balance of High Hardness and High Toughness: Surface hardness reaches HRC 60–65 / HRA 80–90, while maintaining excellent core toughness for effective impact resistance.
Wear Resistance: Wear resistance is 3–5 times that of ordinary steel.
Long Service Life Design: Under standard working conditions, service life is extended by 6–18 months.
Environmental Adaptability: Features acid/alkali and corrosion resistance, with an operating temperature range of -40℃ to 350℃.
Multifunctional Characteristics: Offers advantages of self-lubrication, low friction, and lightweight, with the capability for high-precision customization.
Precision Fit: CNC machined for accurate installation dimensions, effectively reducing the risk of equipment vibration and uneven wear.

Application Fields
Dredging Engineering: Dredge pump housings, pipelines, and related dredging equipment.
Mining and Metallurgy: Crusher liners, chutes, and conveying systems.
Material Handling: Transport and processing equipment for high-abrasion materials such as coal, sand, gravel, and aggregates.
Special Operating Conditions: Other industrial mechanical protection scenarios involving high impact and high abrasion.
