Опис товару
Slitting Separators (also called separator discs or separator wheels) are key components installed on both sides of the top and bottom knife shafts in a steel coil slitting line. Their primary function is to support, guide, and separate the slit strips to prevent contact, tangling, or scratching during recoiling. They ensure straight edges and high product quality.

🎯 Main Purposes of Slitting Separators
Function Category |
Description |
1. Separation |
Separates the slit strips from each other to prevent overlapping, tangling, or rubbing during line operation or recoiling. |
2. Guiding |
Helps guide the strips along an accurate path, ensuring neat edges and proper alignment during recoiling. |
3. Support |
Provides physical support for thin or soft materials (e.g., stainless steel, aluminum), preventing sagging or vibration. |
4. Surface Protection |
Rubber-coated separators prevent scratches, dents, or marks on the edges of the metal strips, improving surface quality. |
5. Improved Product Quality |
Proper use of separators helps maintain consistent strip width and tight, uniform coils, increasing product yield. |
🛠️ Usage & Maintenance Guidelines
✅ Usage Guidelines
-
Correct Installation Orientation: Ensure the separator disc is perpendicular to the knife and fits tightly on the shaft with no play.
-
Proper Spacing: Match separator thickness to slit strip width and spacing requirements to prevent entanglement.
-
Avoid Overloading: Excessive load may damage the separator or misalign the knives, reducing slitting quality.
-
Prevent Contamination: Keep the line clean; avoid metal shavings, oil, or debris that can damage the separator surface.
🧽 Maintenance Tips
-
Regular Wear Inspection: Especially for coated separators—replace aging rubber in time.
-
Clean Shaft and Separator Surfaces: Prevent rust or jamming.
-
Store in Dry Conditions: Avoid moisture to prevent rusting of metal components.
-
Track Service Life and Replacement: Helps with production planning and quality assurance.

-
📎 Additional Recommendations
-
For stainless steel or aluminum (scratch-sensitive materials), rubber-coated separators are recommended.
-
For heavy-duty or high-frequency use, choose nitrided high-hardness steel.
-
Custom designs available: non-standard sizes, special edges (e.g., tapered, anti-slip grooves) can be tailored to specific process requirements.
