High Strength and Toughness Nodular Cast Iron Roller From China for Rebar

High Strength and Toughness Nodular Cast Iron Roller From China for Rebar. By using the centrifugal composite casting process, the surface has high hardness and excellent wear resistance, while the core part is strong and durable, with good resistance to fatigue and impact. The roller surface has high hardness, sufficient wear-resistant layer thickness, low wear rate, long service life, and the replacement cycle of the rollers is significantly extended. Resistant to thermal shock and thermal fatigue under high-temperature rolling conditions, and less prone to thermal cracks, spalling and pitting. The roll body has high resistance to compression, impact and bending. It is not prone to breakage or edge cracking even when faced with material deviations or rolling impacts, ensuring high operationa. The roller surface has high smoothness, the profile plate surface is flat, the dimensions are precise, and the surface quality is excellent. Customizable specifications for hardness and roughness, suitable for various rolling machines, hot and cold rolling production lines, rods, wires, pipes, profiles, etc. Wide adaptability, stable performance, suitable for vehicle grinding, refurbishment and repair, long service life. Full-category customization, compatible with all production lines including cold and hot rolling, bars and wires, sheet metals, and profiles. Combined process + repairable, with lower overall cost.
