High-Performance Industrial Blades for Steel Processing Applications
The steel industry demands ultra-durable cutting solutions for hot rolling, cold rolling, slitting, shearing, and precision metal forming. Our heavy-duty industrial blades are engineered to withstand extreme temperatures, high-impact forces, and continuous operation, delivering longer service life and superior cutting performance in steel mills and metal fabrication plants.
MAIDECAL : Specialized Blades for Steel Processing
Our industrial blades are specifically designed for the paper and corrugated cardboard industry, including applications in:
- Hot-Rolled Steel Knives – For high-temperature cutting (up to 1,200°C) of carbon steel coils & plates.
- Cold-Rolled Steel Blades – Ultra-precise trimming of galvanized, stainless & alloy steel sheets.
- Gantry Transverse Cutting Blades – Heavy-duty shearing for structural beams, pipes & rebar.
- Slitting Disc Knives – Multi-blade circular cutters for high-speed coil slitting lines.
- Arc-Shaped Punching Blades – Contour cutting of irregular steel profiles & automotive parts.
- Flying Shears (Bar & Wire Rod Cutters) – On-line cutting at speeds exceeding 50m/s.
These blades reduce material loss by 20% and extend tool life by 3X compared to conventional steel-cutting solutions.
Technical Advantages & Quality Assurance
Our steel-cutting blades feature advanced material science and engineering to ensure:
- Extreme Wear Resistance – Tungsten carbide (TC) & ceramic coatings for 100+ hour continuous operation
- Thermal Shock Protection – Cryogenically treated alloys prevent edge chipping in hot/cold cutting
- High-Impact Durability – Forged tool steel cores withstand shear forces up to 1,500 MPa
- Precision-Ground Edges – Sub-0.01mm tolerance for burr-free cuts (±5µm microfinish)
- Dynamic Balance Optimization – High-speed stability at 2,000+ RPM (ISO 1940 G2.5 standard)
Result: 60% less downtime and 40% lower operational costs vs. industry averages.
Material Engineering & Manufacturing Process
Blade Materials for Demanding Steel Applications
| Material | Ideal For | Key Benefits |
|---|---|---|
| Tungsten Carbide (TC) | High-speed slitting (>30m/min) | 10X wear resistance vs. HSS |
| Powder Metallurgy HSS (M4/M42) | Hot-rolled steel trimming | Retains hardness at 600°C+ |
| Ceramic-Insert Blades | Abrasive alloy steels | Non-reactivity, zero galling |
| Bimetallic Shear Blades | Guillotine cutting | Hard edge + shock-absorbing core |
Precision Manufacturing Techniques
- 5-Axis CNC Grinding – Micro-bevel edge geometries for cleaner cuts .
- Laser Hardening (HV 1,200+) – Localized surface treatment extends edge retention.
- Vacuum Brazing – Stronger TC/steel bonding (Shear strength >400 MPa).
- Ultrasonic Edge Polishing – Mirror-finish edges reduce friction & adhesion.
