Thermal Instability
High temperatures and pressures cause emulsions to "break" or oils to smoke, creating fire hazards and poor lubrication.

Steel Rolling Fluid Solutions
From hot strip mills to tandem cold rolling, KERUN delivers precision lubrication and cooling to ensure superior surface quality, dimensional accuracy, and maximized mill uptime.
Process Challenges
In steel rolling, microseconds of instability can lead to millions in losses. Thermal breakdown, surface defects, and system fouling are constant threats to your profitability.
High temperatures and pressures cause emulsions to "break" or oils to smoke, creating fire hazards and poor lubrication.
Roller marks, orange peel, staining, or residual iron powder compromises coil value and downstream processing.
Sludge, sticky residues, and microbiological growth clog filters/nozzles, disrupting continuous casting and rolling.
Excessive fluid consumption, high energy usage, and frequent roll changes erode profit margins.
KERUN Solution Approach
Map steel grades, reduction schedules, cooling water chemistry (hardness/Cl⁻) and roll roughness to build a risk baseline.
Match viscosity, EP anti-wear additives and emulsion stability to your mill speed and finish requirements—no over-engineering, just fit-for-purpose chemistry.
Supervise system flushing, fluid charging and initial parameter calibration to ensure lab-proven performance is fully replicated on the mill floor.
Regular refractive index checks, tramp oil monitoring and routine microbial screening to preempt issues and extend fluid life.
Product Systems
KERUN recommends steel rolling product systems according to steel type, rolling line condition, surface target, equipment requirements, media circulation, and maintenance goals.
Typical Applications
Steel rolling fluid performance is critical for production environments where line stability, surface quality, and equipment protection affect large-scale industrial output.
