High-Pressure Descaling Systems for Mild Steel Hot Rolling Applications PressureJet descalers for Mild Steel (MS) rolling mills are specifically engineered to address the oxide scale characteristics of mild steel during hot rolling operations. Our 150–200 bar high-pressure descaling systems are designed for light to medium oxide scale removal, where controlled descaling efficiency is required without aggressive erosion of the base metal. These systems are ideally suited for MS rolling mills, including entry-level rolling mills, secondary descaling zones, pre-rolling cleaning stations, and continuous production lines processing moderate-temperature mild steel billets, blooms, and bars. Built around true high-pressure reciprocating plunger pump technology, PressureJet MS descaling systems deliver consistent jet impact force, uniform spray distribution, and stable long-term performance, ensuring reliable descaling under continuous industrial operation. Technical Description The descaling system operates using a high-efficiency positive displacement triplex plunger pump, engineered to maintain stable pressure and uniform flow even during prolonged duty cycles typical of MS rolling mills. Unlike centrifugal pump-based water cleaning systems, PressureJet’s high-pressure plunger pumps deliver constant hydraulic energy and sustained jet impact force, which is critical for effective mild steel oxide scale fracture and removal. Hydraulic energy is converted into high-velocity flat-jet or fan-jet water sprays through precision-engineered descaling headers and nozzles, enabling efficient oxide scale removal while optimizing water and power consumption. This design enables: • Controlled oxide scale fracture without surface damage to mild steel • Minimal base metal erosion, preserving metallurgical integrity • Reduced water consumption through efficient jet utilization • Lower power requirement per ton of rolled steel compared to higher-pressure descaling systems Key Applications • Mild Steel (MS) TMT bar rolling mills • Small to medium MS rolling mills • Secondary descaling before finishing stands • Mild steel billet and bar surface cleaning systems • Pre-processing descaling for hot mild steel components Engineering Highlights • Operating pressure range: 150–200 bar • Pump type: Continuous-duty triplex reciprocating plunger pumps • Crankshaft design: Forged crankshaft with heavy-duty roller bearings • Plunger material: Solid ceramic plungers for superior wear resistance • Construction: Modular skid-mounted descaling system • Filtration: Multi-stage filtration system to prevent nozzle choking • Hydraulics: Low-pulsation design for stable spray pattern and uniform jet impact Advantages for Mild Steel Rolling Mills • Excellent cost-to-performance ratio for MS descaling applications • Lower energy consumption per ton of mild steel produced • Reduced wear on rolls, guides, and downstream equipment • Simple operation and ease of maintenance • Ideal for MS rolling mills upgrading from low-pressure water cleaning to high-pressure hydro-mechanical descaling technology Ideal Descaling Solution for Mild Steel Applications This 150–200 bar descaler for Mild Steel rolling mills is the ideal solution for customers seeking reliable, industrial-grade MS descaling systems without unnecessary over-engineering, while still benefiting from true high-pressure pump-based descaling technology.
