Roll Coolant Filtration System

About Roll Coolant Filtration System

Our Roll Coolant Filtration System is a specialized filtration unit used in metal rolling mills (especially steel and aluminium processing) to filter and recirculate the coolant used in the rolling process. These systems play a critical role in maintaining the quality of the rolled product, protecting equipment, and extending coolant life.

WHAT IS A ROLL COOLANT FILTRATION SYSTEM?

Its an industrial filtration setup designed to:

ï

• 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.

ï

WHY IS FILTRATION IMPORTANT IN ROLLING MILLS?

ï

• 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.).

ï

SYSTEM COMPONENTS

ï

• Collection Troughs / Tanks: Collect coolant from mill stand area.
• Coarse Pre-Filters: Remove large particles, scale, and chips.

ï

Main Filtration Units

May include:

ï

• Vertical Type Candle Magnetic Separator
• Agitator
• Self-cleaning filtration system
• Oil Skimmer
• Compact band filter

ï

Clean Coolant Tank:ï Stores filtered coolant ready for reuse.

Pump Systems: Transfer coolant through the system and back to the mill.

Cooling Units (Optional): Heat exchangers or chillers to maintain coolant temperature.

Control Panel (PLC / HMI): Manages operations, alarms, and monitoring.

WORKING PRINCIPLE (GENERAL FLOW)

ï

• Dirty coolant from the rolling mill is collected.
• Coarse filtration removes large debris.
• It passes through fine filtration (Compact band filter / Self-cleaning filter / Vertical Type Candle Magnetic Separator / Oil Skimmer)

ï

Clean coolant is cooled (if required).

Coolant is pumped back to the rolling process.

Sludge/particles are collected and disposed of or processed.

COOLANT TYPES

ï

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

ï

APPLICATIONS

ï

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

ï

DESIGN CONSIDERATIONS

ï

• Flow rate (m/hr or LPM)
• Filtration accuracy (micron rating)
• Type and concentration of contaminants
• Type of coolant fluid
• Required temperature control
• Footprint and layout
• Automation and monitoring level

ï

ADVANTAGES

ï

• Improves product quality
• Reduces operational costs
• Environmentally friendly (reduced disposal)
• Ensures equipment longevity
• Consistent rolling process
