Roll Units of High-Accuracy Tension Leveling Machine with 16mm Dia. Work Rolls
Roll units are core vital components of the high-accuracy tension leveling machine. Their primary function is to support work rolls and intermediate rolls, preventing deflection and deformation of 16mm diameter work rolls. Without stable support, roll deformation will badly reduce production output and damage the surface quality of metal sheets and strips.
This series of roll units owns outstanding comprehensive mechanical properties: high surface hardness, uniform hardness distribution over the entire roll body, deep hardened layer, balanced strength and toughness for both roll neck and roll barrel. Besides, they feature superior wear resistance, reliable anti-spalling performance and strong overload impact resistance. These reliable characteristics make the roll units perfectly fit high-speed, large-output and high-precision metal tension leveling production lines, and effectively extend the overall service life of finished metal strips.
The roll units are widely adopted across various industrial sectors, with the largest demand from the metal processing industry. All roll spindles are forged from premium carbon steel and stainless steel. Matched with high-accuracy tension leveling machines, this set of roll units delivers precise positioning, energy efficiency and stable operating performance, so it is widely applied in automotive, home appliance and construction industries. In automotive manufacturing, it processes various automobile structural parts; in home appliance production, it shapes metal casings for refrigerators and washing machines; in construction industry, it fabricates section steel and metal plates.
Furthermore, work roll bending technology is a crucial guarantee for excellent strip flatness. The bending system includes positive bending and negative bending modes. Operators can precisely adjust bending force to control strip thickness uniformity and correct flatness defects, so as to upgrade finished product quality. The matching use of this roll unit and bending technology improves production efficiency and strengthens the market competitiveness of metal finished products.
Technical Parameters of Roll Units
- Roll surface quenching hardness: HRC63 ~ 65
- Hardened layer penetration depth: 3 ~ 5mm
- Surface treatment: Full hard chrome plating on roll surface
- Chrome plating thickness: 0.03 ~ 0.05mm
In general, work rolls are the key functional parts of tension leveling equipment. The performance and processing quality of Roll Units of High-Accuracy Tension Leveling Machine with 16mm Dia. directly determine the surface quality of final metal strips and continuous production efficiency of the whole production line.
