Rtsd 418 Weld Overlay Wear Resistant Cco Thick Plate - China

The RTSD-418 Chromium Carbide Overlay Wear Plate is engineered for extreme abrasion conditions where long service life and stable performance are critical.

As a premium CCO Plate, it combines a tough structural steel base with a high-chromium, high-carbide overlay, forming a durable Chromium Carbide Wear Plate suitable for continuous heavy-duty operation.

With a chromium carbide (Cr₇C₃) volume fraction of approximately 50%, this CCO Wear Plate delivers outstanding resistance to sliding wear, particle erosion, and high-temperature abrasion.

Its hardness range of HRC 58–65 ensures consistent wear protection even under severe material flow and impact conditions.

Their key applications across major sectors:

Construction Machinery Industry

The construction machinery sector relies heavily on overlay wear-resistant plates, as its equipment operates in harsh environments with frequent friction and impact from hard materials (e.g., rocks, gravel, soil).

Core Applications: Excavator bucket teeth, loader buckets, bulldozer blades, asphalt paver screeds, and road roller compactors.

Mining Industry

Mining operations involve intensive handling of high-hardness ores (iron ore, copper ore, etc.

) and aggregates, making wear a primary challenge for equipment.

Overlay plates are essential here to withstand extreme abrasion.

Core Applications: Crusher liners (jaw crushers, cone crushers), conveyor chutes, hopper liners, ore storage bins, and vibrating screen decks.

Building Materials Industry (Cement & Ceramics)

In cement and ceramic production, raw materials (limestone, clay, quartz) and finished products (clinker, ceramic tiles) are highly abrasive, demanding wear-resistant components to sustain production efficiency.

Core Applications: Vertical mill liners (for cement raw material grinding), roller press plates, cement kiln inlet chutes, ceramic raw material crushers, and tile press molds.

Power Generation Industry (Coal-Fired Power Plants)

Coal-fired power plants depend on coal as fuel, and coal particles (especially those with high ash content) cause severe abrasive and erosive wear to equipment.

Overlay plates protect key components and maintain stable power generation.

Core Applications: Coal pulverizer liners, boiler economizer tubes (with thin overlay protection), coal conveying hoppers, and ash handling system chutes.

Metallurgical Industry

Metallurgical processes (ironmaking, steelmaking) involve high temperatures (up to 1, 000°C+) and abrasive materials (iron ore, coke, molten slag), requiring overlay plates with both wear resistance and heat stability.

Core Applications: Blast furnace bell/hopper liners, taphole liners, steel rolling mill guide plates, and continuous casting machine rolls.
