Forged Steel Backup Roll, Heavy Duty Mill Backup Roller for Hot Cold Rolling Mill Steel Plant

Short Description:

Forged Steel Backup Roll, Heavy Duty Mill Backup Roller for Hot Cold Rolling Mill Steel Plant

Runxing forged steel backup roll is manufactured by integral forging process, specially designed for heavy-load rolling mill operation. It adopts high-quality alloy steel raw material, through strict heat-treatment including quenching and tempering to achieve high core strength, excellent toughness and anti-fatigue performance. This backup roll bears huge rolling force during production, supports work rolls effectively, improves mill rigidity and stabilizes strip flatness. Strict ultrasonic inspection is implemented for each product to avoid internal material defects. Precise CNC turning and finishing machining guarantee strict dimensional tolerance and good assembly match with mill housing. It resists heavy impact load and reduces roll-body crack risk under long-time continuous working condition. Our backup rolls are widely applicable for hot rolling mill, cold rolling mill and strip processing line. We can customize various diameters, barrel length and shaft-end dimensions according to customer’s technical drawings. Each roll will pass complete quality test before delivery, supporting third-party inspection. Reliable mechanical performance helps steel mills lower roll replacement frequency and cut overall production cost.
