Unmatched Wear Resistance
Tungsten carbide rings are the most wear-resistant rings available, ensuring long-lasting performance even in demanding industrial environments.
Exceptional Hardness
Tungsten carbide is approximately 10 times harder than gold, 5 times harder than tool steel, and 4 times harder than titanium.
Durability and Luster
Thanks to their extreme hardness, tungsten carbide rings maintain their shape and shine far longer than any other type of ring on the market.
Permanent Polishing
Known as the "permanent polishing ring," tungsten carbide rings retain their polished finish with minimal maintenance.
Bend-Resistant
Unlike traditional metal rings, tungsten carbide rings do not bend, ensuring consistent performance over time.
Applications
Tungsten carbide roll rings are essential in various rolling applications, including:
Bar and wire rod mills
Hot and cold strip mills
Plate rolling mills
Non-ferrous mills
Seamless pipe rolling mills
High-speed finishing mill roll sleeves
Material Characteristics
High-speed steel (HSS) roll rings are manufactured in compliance with the national cast steel roll standard GB/T1503-2008. These rings are composed of a steel-based alloy enriched with vanadium, nickel, tungsten, molybdenum, niobium, and cobalt. Key characteristics include:
Carbon content: <1.6%
Phosphorus content: <0.03%
Chromium content: <5%
Sulfur content: <0.03%
These carefully controlled compositions ensure superior wear resistance, impact toughness, and resistance to micro-cracks, block loss, and ring bursts. The precise control of tungsten content prevents segregation during centrifugal casting, resulting in minimal hardness drop after re-grinding and consistent steel-passing performance.
