Precision Leveling Line Rolls for Metal Strip Processing
Leveling line rolls are indispensable core components of rolling mill and metal straightening equipment. The overall performance, machining accuracy and manufacturing quality of these rolls are the key factors that determine the surface finish, flatness precision and continuous production efficiency of finished metal plate and strip products, serving as the foundation for stable industrial rolling production.
As the key matching parts of tension straightening machines, our professional leveling line rolls are specially designed to support functional rolls and intermediate rolls during high-load operation. They effectively restrain roll deflection, bending and structural deformation caused by long-term tension processing, avoiding defective products and output reduction induced by roll deformation, and stably guarantee the consistent processing quality of metal plates and strips.
Our leveling line rolls adopt standardized high-standard manufacturing processes, with excellent comprehensive mechanical properties. The rolls feature ultra-high surface hardness and uniform hardness distribution, paired with a deep integral hardened layer on the roll body. Both the roll neck and roll barrel are optimized for structural strength and impact toughness. Meanwhile, the products deliver outstanding wear resistance, anti-peeling performance and strong anti-overload capability, perfectly adapting to the operating demands of high-speed, large-scale and high-precision metal straightening equipment, and maintaining long-term stable operation of production lines.
Fabricated with high-quality carbon steel and stainless steel raw materials, our leveling line rolls are widely applicable in metal processing and steel rolling industries. Supported by high-precision tension straightening equipment with excellent stability and operational efficiency, the rolls cater to diverse industrial production scenarios. They are widely used for processing automotive body and chassis parts, metal shell accessories for refrigerators and washing machines in the home appliance industry, as well as various section steel and steel plate materials for the construction industry.
Furthermore, professional roll bending technology is adopted to further optimize strip leveling quality, including positive bending and negative bending adjustment modes. By precisely regulating the bending force, the equipment can accurately control the thickness uniformity and overall flatness of metal strips, effectively eliminating surface defects and improving finished product qualification rate. This mature processing technology greatly boosts overall production efficiency and enhances the core market competitiveness of metal processing products.
Technical Parameters of Leveling Line Rolls
- Surface quenching hardness: HRC 63 ~ 65
- Quenched hardening layer depth: 3 ~ 5mm
- Surface treatment: Hard chrome plating
- Chrome plating thickness: 0.03 – 0.05mm
In industrial rolling and leveling systems, high-performance leveling line rolls occupy a pivotal position. Their mechanical stability and processing quality directly dominate the final quality standard and production capacity of metal strip products, which is an irreplaceable key link in metal processing production.
