CX and CX-Plus Series Mill Rolls
Count on CX and CX-Plus Series Rolls to Perform in Aggressive Environments
NCCM® CX and CX-Plus Series Mill Rolls are the ideal choice for use with harsh caustic and acidic chemistries. They are specially engineered to perform in aggressive environments such as electrolytic lines for tinning, chroming or galvanizing; or on pickling, caustic cleaning or coil coating lines. They can make a significant contribution to increased productivity in the following ways:
Reduced Line Downtime
One NCCM® mill roll can last longer than up to 100 rubber rolls. That means fewer roll changes which reduces costly line downtime and fewer unplanned stops. Environmental savings include a significant reduction in the cost of transporting rolls, a reduction in the space required to store spare rolls and a significant reduction in waste disposal.
Reduced maintenance costs
NCCM Mill Rolls are resistant to cuts and gouges so they require fewer repairs that reduce productivity. If a problem does occur, the rolls can be quickly and easily repaired instead of replacing the roll.
Improved process control
NCCM mill rolls are uniformly porous. This results in a roll that maintains tight contact with the metal strip for optimal writing performance. The rolls have up to 24 times greater coefficient of friction compared to rubber or urethane rolls which improves material control by reducing metal coil slippage and hydroplaning.
Maintaining the integrity of process fluids
The porosity of NCCM Mill Rolls makes the roll compressible and better able to conform to variations in gauge thickness. Maintaining consistently tight contact across the metal coil produces uniform wringing which significantly reduces chemical carry-out from tank to tank and reduces the need for drying. Because tank chemistry is more consistently contained, chemical disposal costs and the need to add chemicals are reduced.
Fewer coil surface defects
Metal shards and debris can become trapped on the surface of rubber or urethane rolls causing defects on the metal coil. The porous, non-woven material of NCCM Mill Rolls tends to embed small particles into the roll, where it is less likely to come into contact with the metal surface.
Lower energy costs
NCCM Mill Rolls have a high coefficient of friction which can eliminate the need for auxiliary motors while simultaneously allowing faster line processing speeds and better steering. Because NCCM rolls provide thorough, uniform wringing, the need for drying can be reduced or eliminated as well.
Overall, the use of NCCM Mill Rolls results in increased operational efficiency through less downtime and faster line speeds.
