Henan San Kuang Machinery Technology Co., Ltd., established in 2014 with over 10,000 square meters of manufacturing facilities, specializes in precision-engineered components for industrial machinery. Our hardened alloy steel draw rolls represent a critical advancement for high-speed wire drawing operations, engineered to deliver exceptional durability and performance in demanding production environments. With an annual export value exceeding US$2.5 million and serving markets across six continents, we bring global expertise to your production line. These components are manufactured under strict quality protocols including ISO9001 and ISO14000 certifications, ensuring reliability that wire manufacturers can trust for their most intensive applications.
Our draw rolls undergo specialized hardening treatments to achieve superior surface hardness and wear resistance. This process extends operational lifespan significantly compared to conventional rolls, particularly crucial for high-speed operations where surface degradation causes costly downtime. Key technical features include:
- Microstructure Optimization: Proprietary heat treatment creates a martensitic structure with controlled carbide distribution
- Surface Integrity: Grinding tolerance maintained at ≤ 0.005mm for consistent wire surface quality
- Thermal Stability: Maintains dimensional accuracy at sustained temperatures up to 150°C
| Parameter | Specification |
|---|---|
| Core Hardness | HRC 58-62 |
| Surface Hardness | HV 750-850 |
| Diameter Range | Ø80mm - Ø300mm |
| Maximum Line Speed | 25 m/s |
Operational advantages translate directly to cost savings:
- Reduces replacement frequency by 40-60% versus standard carbon steel rolls
- Maintains dimensional stability through 10,000+ operational hours
- Minimizes wire surface defects (
- Compatible with all common lubricants including extreme-pressure (EP) types
With shipping capabilities through major Chinese ports including Shanghai and Qingdao, we ensure timely delivery to global customers. Our products reach manufacturers in over 15 markets annually, from North American precision engineering facilities to Southeast Asian wire production hubs. The combination of our OHSAS18001 certified manufacturing processes and rigorous material selection results in components that outperform industry averages in mean time between failures (MTBF) by significant margins.
Frequently Asked Questions:
Q: What is the typical service life of these draw rolls?
A: Under normal operating conditions (≤20 m/s line speed), our hardened alloy rolls typically achieve 12-18 months of continuous service before requiring reconditioning.
Q: Can you manufacture rolls to match our existing machine specifications?
A: Yes, we routinely produce custom-dimensioned rolls. Provide technical drawings or sample components for precise replication.
Q: Do you provide surface coating options?
A: Tungsten carbide and chromium-based surface treatments are available for specific abrasion resistance requirements.
Q: What quality documentation accompanies shipments?
A: All shipments include material certification (including traceability), heat treatment records, and final inspection reports.
Q: How do you ensure dimensional accuracy?
A: We employ CNC profile grinding with laser measurement verification, maintaining tolerances within ±0.003mm.
Q: What is your minimum order quantity?
A: Standard production MOQ is 10 units, with sample quantities negotiable for established partners.
Q: Can you supply complete roll assemblies?
A: We provide both individual rolls and pre-assembled cartridge units with bearings and seals installed.
Q: What industries typically use these components?
A: Primary applications include copper wire production, steel cord manufacturing, and specialty alloy wire processing facilities.
