ROLL COOLENT FILTERATION SYSTEM

About ROLL COOLENT FILTERATION SYSTEM

ROLL COOLENTFILTERATION SYSTEM.!

Our RollCoolant Filtration System is a specialized filtration unit used in metalrolling mills (especially steel and aluminium processing) to filter andrecirculate the coolant used in the rolling process. These systems play acritical role in maintaining the quality of the rolled product, protectingequipment, and extending coolant life.

WHAT IS AROLL COOLANT FILTRATION SYSTEM?

Its anindustrial filtration setup designed to:

• Clean and recycle coolant (oil or emulsion) used in rolling mills.
• Remove contaminants such as metal fines, scale, and debris.
• Maintain fluid temperature, pressure, and cleanliness to ensure efficient rolling operations.

 WHY IS FILTRATION IMPORTANT IN ROLLING MILLS?

• Improves surface finish of the rolled material.
• Reduces tool and roll wear.
• Minimizes downtime due to maintenance.
• Increases coolant lifespan and reduces disposal costs.
• Prevents clogging and wear of downstream equipment (like heat exchangers, pumps, etc.).

SYSTEMCOMPONENTS

1. Collection Troughs / Tanks
• Collect coolant from mill stand area.
2. Coarse Pre-Filters
• Remove large particles, scale, and chips.
3. Main Filtration Units
• May include:
• Vertical Type Candle Magnetic Separator
• Agitator
• Self-cleaning filtration system
• Oil Skimmer
• Compact band filter
4. Clean Coolant Tank
• Stores filtered coolant ready for reuse.
5. Pump Systems
• Transfer coolant through the system and back to the mill.
6. Cooling Units (Optional)
• Heat exchangers or chillers to maintain coolant temperature.
7. Control Panel (PLC / HMI)
• Manages operations, alarms, and monitoring.

WORKINGPRINCIPLE (GENERAL FLOW)

1. Dirty coolant from the rolling mill is collected.
2. Coarse filtration removes large debris.

• It passes through fine filtration (Compact band filter / Self-cleaning filter / Vertical Type Candle Magnetic Separator / Oil Skimmer)

3. Clean coolant is cooled (if required).
4. Coolant is pumped back to the rolling process.
5. Sludge/particles are collected and disposed of or processed.

 COOLANT TYPES

• Water-based emulsions (common in aluminium mills)
• Oil-based coolants (used in cold rolling of steel)
• Synthetic or semi-synthetic fluids

APPLICATIONS

• Steel cold rolling mills
• Aluminium strip mills
• Tandem rolling lines
• Hot/cold rolling stands
• Pickling & finishing lines
