- BDM rollers play a critical role in hot rolling mills.
- They are positioned just before the roughing mill.
- Their job is to hold onto the rolling stock, maintaining tension and stable forward transportation.
- BDM rollers operate on a horizontal cantilever structure with an air cylinder and a double roll device.
The usage of BDM rollers in steel rolling mills.
-
Tension Control :
- BDM rollers play a crucial role in maintaining tension during the rolling process.
- As the material (such as steel) passes through the rolling mill, it experiences significant forces and elongation.
- BDM rollers ensure that the material remains under controlled tension, preventing slippage or buckling.
-
Stable Forward Transportation :
- BDM rollers are strategically positioned just before the roughing mill.
- Their primary function is to hold onto the rolling stock (e.g., steel billets or slabs) and facilitate its smooth movement.
- By providing stable forward transportation, BDM rollers contribute to efficient and continuous rolling operations.
-
Horizontal Cantilever Structure:
- BDM rollers operate on a horizontal cantilever structure.
- This design allows them to support the material without interfering with the rolling process.
- The cantilever arrangement ensures that the material moves along the desired path without lateral deviations.
-
Air Cylinder and Double Roll Device:
- BDM rollers are equipped with an air cylinder mechanism.
- The air cylinder exerts pressure on the rolls, maintaining the necessary grip on the rolling stock.
- The double roll device ensures uniform contact with the material, preventing any uneven deformation.
