In steel rolling production, core bottlenecks like “rapid roll groove wear, frequent roll changes, low yield, and roll breakage risks” hinder efficiency and cost optimization. High-speed steel (HSS) rolls—equipped with top-tier material technology and comprehensive performance advantages—precisely address these pain points and fuel efficient production.
🚨 Core Pain Points: Are You Troubled by These?Poor wear resistance → Rapid groove wear, unstable material shape, low qualification rate
- Poor wear resistance → Rapid groove wear, unstable material shape, low qualification rate
- Frequent roll/groove changes → Long downtime, reduced mill operation rate
- Prone to pitting, spalling, groove cracking, roll breakage → High production risks & maintenance costs
- Back-up roll inventory backlogs → Capital occupation, weakened comprehensive benefits
- Insufficient surface finish + uncontrollable negative tolerances → Weak market competitiveness
✨ HSS Rolls: High Performance Meets Pain Point Solutions
1. Dual Breakthroughs in Material & Technology
Adopting centrifugal composite casting, the outer layer is formulated with vanadium, chromium, tungsten, niobium, and other high-end alloy elements—forming a dense structure under high-speed rotational cooling.
Key traits:
✅ Superb hardenability: No obvious hardness drop from surface to inner working layer
✅ Excellent red hardness: Stable performance at high temperatures (avoids premature failure)
✅ Stable core structure: High-strength alloy ductile iron core (eliminates roll breakage/groove cracking)
2. Overlapping Advantages for Core Value
✅ Cost Reduction: Oxide film enhances wear resistance → Fewer roll changes, less downtime, lower consumption & inventory costs
✅ Quality Upgrade: Superior thermal stability → Precise dimensional accuracy, improved surface finish, and tight negative tolerance control
✅ Wide Adaptability: Fits pre-splitting/finishing of plain bars, high-speed wires, hot-rolled strip steel, section steel, special steel, etc.—compatible with various mill stands
3. Professional Guidance for Worry-Free Use
- Tailored processing schemes: Specified tools (boron nitride S1408, CBN) + key parameters (turning speed 20~30 rpm, feed rate 0.2~0.6 mm/r)
- Detailed usage norms: Cooling water temperature ≤40℃ | Pressure 0.4~0.6MPa | Water flow per groove ≥500L/min | Optimized cooling methods + water quality control
