Metallurgical Tribology & Engineering Direct Answer
Continuous casting machines (CCM) and hot rolling mills present extreme tribological hazards: radiant heat from 1,000°C molten steel slabs, high-pressure descaling water washouts, and severe flammability risks near ladle turrets and tundish cars. Standard mineral hydraulic oils pose catastrophic fire hazards if a high-pressure line ruptures near molten metal. FOSS Steel Metallurgy Lubrication Solution provides: (1) Fire-Resistant Hydraulic Fluid HFDU 46/68 (synthetic polyol ester-based, certified to ISO 12922 and Factory Mutual FM Approval 6930, with a fire point > 360°C per ASTM D92 and self-extinguishing behavior, readily biodegradable > 80% per OECD 301B); (2) High-Temperature Water-Resistant Calcium Sulfonate Complex Grease (NLGI 2 with dropping point > 300°C per ASTM D2265, water washout < 1.0% at 79°C per ASTM D1264, and Four-Ball weld load > 400 kgf per ASTM D2596) engineered for continuous caster guide roller bearings subjected to constant water deluge; and (3) Heavy Demulsifying Gear Lubricant L-CKD 320/460 (water separation < 10 minutes at 82°C per ASTM D1401) protecting hot strip mill pinion stands and reduction drives. This solution eliminates plant fire hazards, extends caster bearing life threefold, and cuts water-contaminated grease consumption by 45%. Supplied in UN 208L steel drums and 1,000L IBC totes.

Primary Steel Mill Application Sections
Engineered specifically for high-stress industrial machinery, minimizing friction coefficients and extending component service life.
Continuous Casting Segment Rollers
Calcium sulfonate grease prevents bearing seizure despite direct cooling water jets and radiant heat from red-hot steel slabs.
Ladle Turrets & Electric Arc Furnace Hydraulics
Synthetic ester HFDU eliminates fireball risks during hydraulic hose ruptures adjacent to 1,600°C molten metal.
Hot Strip Mill Roughing & Finishing Stands
Heavy gear oils maintain lubricating film thickness under severe torque reversals and mill shudder.
Walking Beam Reheating Furnace Roller Bearings
High-temperature greases resist grease liquefaction and carbonization in furnace charging mechanisms.
Batch Quality Control & Standard Verification
Strict five-stage quality checkpoint from raw base oil tank unloading to finished drum sealing.
Fire Point & Flash Point Verification (ASTM D92)
Every batch of HFDU tested to ensure fire point exceeds 360°C with self-extinguishing properties.
Water Washout Resistance Test (ASTM D1264)
Confirms calcium sulfonate grease washout loss remains strictly under 1.0% at 79°C.
Demulsibility in Process Water (ASTM D1401)
Water phase separates completely in under 10 minutes at 82°C for easy oil reclamation.
24-Month Sealed Retention Archive
Archived 1L production samples stored with complete QA lot traceability.
Export Packaging, Palletization & Container Loadability
Supplied in standard UN 1A1 cold-rolled steel 208L drums (80 drums per 20GP container = 16,640 liters), 180kg open-head steel drums for greases, and 1,000L IBC totes.
