Double Cone Uncoiler

The Double Cone Uncoiler is an essential coil handling device designed for high-capacity steel coil processing lines. With a maximum load capacity of 15 tons, this uncoiler is ideal for heavy-duty applications requiring precise centering, secure coil support, and seamless feeding into the production line.

Key Features

• Max Coil Weight: 30 Tons

• Coil Inner Diameter Range: 508mm / 610mm

• Coil Width: Up to 1600mm (customizable)

• Hydraulic expansion & centering system

• Motorized rotation for smooth decoiling

• Stable base structure with anti-slip support

Why Choose a Double Cone Uncoiler?

• Precise Centering: Automatically aligns coils for stable feeding.

• Time-Saving: Compared to single-arm or double-head uncoilers, double cone design requires less coil changeover time.

• High Stability: Prevents coil tilting or slipping during operation.

• Compatible: Can be integrated with slitting lines, cut-to-length lines, and ERW tube mills.

Typical Applications

This equipment is widely used in:

• Steel Tube Mill Lines

• Cold Roll Forming Lines

• Slitting and Cut-to-Length Lines

• Heavy Coil Storage and Unwinding Systems

• 3. Workflow Overview

   

  The Double Cone Uncoiler plays a crucial role in the initial stage of coil processing. It ensures smooth and stable unwinding of heavy steel coils, feeding material into subsequent equipment such as straighteners, feeders, slitting machines, or tube mill formers. Below is a typical workflow:

  1. Step 1: Coil Loading – The coil is loaded onto the double cone using a crane or coil car.

  2. Step 2: Hydraulic Expansion – The cones expand inward to securely center and grip the coil core.

  3. Step 3: Coil Rotation – Motorized rotation begins to slowly uncoil the strip under controlled tension.

  4. Step 4: Material Guiding – The strip is guided into a pinch roll or straightening unit for alignment and leveling.

  5. Step 5: Continuous Feeding – The strip enters the main processing unit (e.g., slitter, tube forming machine, etc.).

  This workflow ensures continuous, stable material feeding with minimal operator intervention and high efficiency.
