Four-Roller Mill for Hot Strip Rolling | 4-Hi Strip Rolling Mill

Our four-roller strip rolling mill, also known as 4-high rolling mill, is specialized equipment for hot narrow/wide strip and cold rolled strip manufacturing. Its classic 4-roll structure consists of two small work rolls for thickness reduction plus two large backup rolls to eliminate work roll bending. This design delivers ultra-tight thickness tolerance and perfect strip flatness for carbon steel, mild steel and low alloy steel. Equipped with hydraulic screw-down, roll cooling system and reserved AGC automatic gauge control interface, it ensures stable continuous high-speed rolling for small and medium strip production lines with much lower investment than heavy-duty large strip mills. Processing Range： Hot strip thickness 1.5–8mm, cold strip thickness 0.5–2mm; applicable strip width 100–800mm (customized). 4-Roll Anti-Deflection Structure： 2 work rolls matched with 2 heavy backup rolls to effectively reduce roll deflection and improve strip flatness. Standard Roll Size Options： Work roll Φ150–Φ400mm, backup roll Φ400–Φ800mm to fit different strip thickness and width demands. Precise Thickness Control： Tolerance reaches ±0.05mm for cold strip and ±0.1mm for hot strip. Hydraulic AGC Screw-Down System： Real-time automatic thickness adjustment for consistent finished strip gauge. Circulating Roll Cooling System： Stabilizes roll temperature during long-hour high-speed rolling to avoid dimension deviation. Cost-Effective Mini-Mill Solution： Lower upfront investment compared with large industrial strip rolling mills, widely applied in small and medium steel factories.
