Roller Tables For Strip Mills And Rolling Mills

Roller Tables For Strip Mills And Rolling Mills

Customized processing according to customer drawings
The customer provides detailed component drawings, and our technical staff can give strengthening technology proposals and suggestions. The common roller surface is not wear-resistant, easy to stick to steel, and easy to corrode. Our company sends technical staff to communicate with customers and suggest surface laser cladding or submerged arc welding to strengthen the roller surface hardness and wear resistance, corrosion resistance, high temperature resistance, and non-stick steel phenomenon, which can increase the service life of the workpiece and reduce the cost of replacement.

Overall Dimension

Our company focuses on providing customized production and surface strengthening and upgrading services for high-precision roller tables for strip rolling, hot and cold rolling and special metal processing production lines. Based on the drawings of parts provided by customers, we not only strictly manufacture according to the drawings, but also rely on a team of senior engineers to actively intervene in technical optimization. We tailor-make strengthening process solutions for industry problems such as easy wear, steel sticking, and corrosion on the roller surface, significantly extending the service life of the roller system and reducing customer operation and maintenance costs.

Core service value

1. Customization according to drawings + technology empowerment dual drive
Precise processing according to drawings: strictly analyze customer drawings to ensure that the dimensional tolerance (±0.05mm), shape and position accuracy and assembly requirements of the roller table are 100% up to standard.

Process optimization suggestions: Engineers deeply communicate the working conditions (temperature, load, medium), and propose material upgrades and structural strengthening solutions for the original design to avoid potential failure risks.

2. Roller surface strengthening technology solution
▸ Laser cladding strengthening
Using nickel-based alloy/tungsten carbide powder, a 0.5-3mm strengthening layer is clad on the roller surface through high-energy laser, the hardness can reach HRC 60+, and the wear resistance is increased by 3-5 times, which completely solves the problem of steel sticking.
Advantages: small heat-affected zone, no deformation of the substrate, suitable for high-precision roller repair.

▸ Submerged arc welding surfacing strengthening
Multi-layer and multi-pass surfacing of cobalt-based or martensitic alloys to form a dense corrosion-resistant layer, resistant to high-temperature oxidation (≤800℃) and acid/alkali medium corrosion.
Advantages: Cost-effective, suitable for batch surface treatment of large roller tables.

3. Full life cycle service support
Pre-sales: Free roller failure analysis report, recommending the most cost-effective substrate and coating combination.
In-sales: Real-time sharing of processing progress, support for video factory inspection and key process quality sampling.
After-sales: Provide roller surface repair service to extend the product life cycle.

Comparison of technical advantages
Pain points of traditional roller tables The effectiveness of our strengthening solution
Low hardness of roller surface (below HRC 45) Hardness HRC 58-62, wear resistance ↑300%
Frequent steel sticking affects production continuity Special alloy coating achieves "zero steel sticking"
High temperature oxidation causes cracking and peeling High temperature resistant coating runs stably for >2 years
Corrosive media shortens life Acid and alkali corrosion resistance extends life by 4 times
