Steel & Metal Plants

Rolling mills and foundries deploy bypass filtration units to handle heavy particulate contamination and high thermal stress in gearboxes and hydraulic-lube systems.

Core Applications in Steel Plants

• Blast Furnace & Coke Oven Hydraulics: Mud guns, tap-hole drill rigs, and furnace top charging systems rely on high-pressure hydraulics. Filtration machines keep fluids completely free of fine coke dust and iron grit to protect sensitive proportional valves.
• Continuous Casting Machines (CCM): Segment drive cylinders adjust mold widths under intense heat and continuous water spray. Water entry into hydraulic packs is a constant threat. Online vacuum dehydration systems are hooked up to continuously remove water down to under 100 ppm.
• Hot & Cold Rolling Mill Lubrication: Pinion gearboxes and backup roll bearings handle immense mechanical crushing forces. They utilize huge volumes of high-viscosity gear oils (ISO VG 220 to 460). High-capacity filtration loops continuously extract hard metallic spalling particles before they score roll necks.
• Hydraulic Automatic Gauge Control (AGC): AGC systems regulate strip thickness in real time with micron-level accuracy using high-frequency servo cylinders. To prevent any control lag or hunting, the hydraulic fluid must be strictly polished to an elite NAS 4 to NAS 5 cleanliness level.
• Slabs/Blooms Lifting Crane Gear Boxes: These heavy-duty crane gear boxes are lubricated by gear oil and the gears and bearings come under tremendous loads, both static and transitional. Clean oil helps reduce gear and bearing breakdowns.
