Pinch Rolls
Pinch Rolls are specialized rolls used in rolling mills to control, guide, and transport the rolled material between different mill stands or after the final rolling pass. They consist of a pair of power-driven rolls that grip (or "pinch") the hot rolled product, such as wire rods, bars, or strips, and help direct it along the desired path—especially towards coilers, cooling beds, or further processing units.
Dimensions:-

| Roll Width | 120 – 250 mm | 80 – 150 mm |
| Face Length | 200 – 350 mm | 150 – 250 mm |
| Groove Profile | Flat or Single Groove | Smooth / Barrel-shaped |
| Roll Material | Adamite / Alloy Cast Steel | Forged Steel / Ductile Iron |
How Pinch Rolls Work
- Located at exit points of finishing mills, or before shears and downcoilers, pinch rolls grab and accelerate the product to maintain continuous flow.
- One or both rolls are motor-driven to provide the necessary pulling force.
- The material is gripped between the two rolls and then smoothly guided out or into the next process with minimal distortion or deformation.
Functions of Pinch Rolls
- Guide the Rolled Product Ensures smooth transfer of hot rolled material into cooling beds, downcoilers, or further processing lines.
- Accelerate Product Flow Provides necessary tension and speed to maintain a continuous rolling line without material breakage.
- Prevent Coil Collapse or Bending Ensures straight, stable feeding into coilers or winders to produce perfect, uniform coils or bundles.
- Support Automatic Operation Essential for high-speed, automated rolling mills where consistent product handling is critical.
