🔧 1. Slitting Knives

Slitting knives are the core cutting components used in slitting lines. They are designed to longitudinally slit wide steel coils into narrower strips. Suitable for a wide range of materials including stainless steel, carbon steel, galvanized steel, silicon steel, and aluminum.

Features:

  • Premium Materials: Commonly used materials include alloy tool steel and powder metallurgy high-speed steel (e.g., D2, SKD11, H13, Cr12MoV, ASP2053).

  • High Hardness: HRC 58–65 for excellent wear resistance and long service life.

  • Sharp Edges: Ensure clean cuts with minimal burrs.

  • Precise Heat Treatment: Delivers superior heat resistance and fracture toughness.


🧩 2. Slitting Spacers

Slitting spacers are placed between slitting knives to maintain consistent knife spacing and ensure precise slitting. They are essential for knife gap adjustment, positioning, and cushioning.

Features:

  • High Dimensional Accuracy: Tolerance up to ±0.001 mm.

  • Durable Materials: Typically made from high-hardness tool steel or stainless steel.

  • Surface Finishing: Includes black oxide, chrome plating, or nickel plating.

  • Various Types Available: Includes rubber spacers, metal shims, and solid precision spacers.

🛠 Maintenance Guidelines

🔪 Slitting Knives

  • Regular Sharpness Check: Regrind when burrs appear or cutting quality declines.

  • Use Proper Cleaning Agents: Avoid metal debris buildup on the blade edge.

  • Storage: Keep knives separated using dedicated racks or boxes to avoid chipping.

  • Regrinding Schedule: Typically every 8–12 hours of cutting, depending on material hardness.

  • Avoid Overheating: Control cutting pressure and speed to prevent annealing or deformation.

🧩 Slitting Spacers

  • Avoid Scratches and Damage: Ensure spacer surfaces remain smooth for precise positioning.

  • Rust Prevention: Apply anti-rust oil regularly and clean before use.

  • Dimensional Calibration: Verify thickness when adjusting for different material gauges.

  • Labeled Storage: Store different thicknesses separately and clearly marked to prevent mix-up.

Ferrite Impeder Rods FAQs

What are Impeder used for?

Consumable products for high frequency welding of tubes assembly Impeders

What does an impedance consist of?

Fiberglass+Ferrite+copper end

Are these impeder sizes customizable?

Yes, the impeder can be customized to fit different tube mill specifications based on customer needs.

What is the function of the ferrite impeder?

The main function of an impeder is to increase the impedance of the parasitic current path around the inner circumference of the tube, concentrating the magnetic flux generated by the current in the working coil, thereby inducing more energy into the tube.

What are the types of impeders?

Impeders are mainly divided into Through Flow Impeders and Return Flow Impeders
