Bimetallic Composite Wear Plates – FAQ
Q1: What are bimetallic composite wear plates, and how are they manufactured?
A: Bimetallic composite wear plates (clad or hardfaced liners) are dual-layer steel plates fused together through professional metallurgical processing. The outer working layer adopts high-chromium steel and special tool steel with high hardness, delivering excellent anti-wear performance for harsh working environments. The bottom base layer is carbon steel or low-alloy steel, featuring great toughness and easy processing and installation for on-site use.
We adopt mature liquid-solid cladding and surfacing welding processes for production. The two steel layers form an integral high-strength combination with no gaps. This sturdy integrated structure avoids peeling and delamination, even under heavy impact and long-term high-load working conditions.
Q2: Why are bimetallic liners superior to traditional monolithic steel plates for steel mill applications?
A: Traditional single solid steel plates have unavoidable performance limitations. High-hardness wear-resistant steel is brittle and easily cracks when subjected to strong impact. In contrast, high-toughness steel resists impact well but wears rapidly, requiring frequent part replacement and causing unplanned production downtime.
Our dual-layer bimetallic plates fix this industry flaw effectively. The surface alloy layer boasts a hardness of up to HRC 53-55 to resist severe abrasion, while the tough steel base layer buffers massive impact from rolling equipment. This optimized structure extends the service life of wear parts by 3-5 times compared with conventional steel plates, greatly reducing mill maintenance frequency, downtime and overall operating costs.
Q3: What are the main rolling mill applications of these composite wear plates?
A: Our heavy-duty bimetallic wear plates are engineered for high-friction and high-impact working areas of steel rolling mills, with core application scenarios as follows:
Mill Housing Liners: Protect the mill main frame from long-term friction and mechanical wear.
Chock Wear Plates: Installed on work roll and backup roll chocks to keep equipment alignment accurate and ensure stable rolling quality.
Guide Plates & Entry/Exit Liners: Endure continuous high-speed friction during the passage of hot and cold rolled steel plates at mill inlet and outlet positions.
