تفصیل

Main drive gearboxes for steel rolling mills are engineered to deliver exceptional torque and withstand extreme shock loads in hot and cold rolling operations. These heavy-duty units ensure reliable power transmission between the motor and work rolls, supporting continuous high-production environments in steel plants worldwide.

پروڈکٹ کا جائزہ

These gearboxes serve hot strip mills, cold rolling mills, and plate mills. Core strengths include high output torque capacity up to 2,500 kNm, robust parallel-shaft or planetary configurations, and design features optimized for reversing duty, impact loads, and elevated operating temperatures typical in steel rolling operations.

تکنیکی پیرامیٹرز

کام کرنے کا اصول

Power from the main drive motor is transmitted through multiple stages of precision helical or bevel-helical gears. The high-torque output shaft connects directly to the work roll or pinion stand. Reinforced housings and optimized tooth profiles absorb the heavy reversing loads and impact forces typical in rolling mill operations while maintaining efficient power transfer.

بنیادی فوائد

ساخت اور مادی دستکاری

Housings are fabricated from high-strength steel plate or cast in QT500 ductile iron with internal ribbing for rigidity. Gears are precision ground from case-hardened alloy steel (20CrMnTi or 42CrMo). Large-diameter shafts and heavy-duty spherical roller bearings handle combined radial and axial loads. Advanced sealing and forced lubrication systems protect components in high-temperature, dusty mill environments.

عام درخواست کے منظرنامے۔

Hot Strip Mill Stands: Delivers precise, high-torque power to work rolls during continuous high-speed rolling with frequent direction changes.

Cold Rolling Mills: Provides stable torque and accurate speed control for high-precision strip thickness reduction.

Plate and Section Mills: Handles extreme impact loads in heavy plate rolling and structural section production lines.

سلیکشن گائیڈ

Calculate peak and continuous torque requirements including starting loads and rolling forces. Determine the required ratio for target roll speed. Consider mounting orientation, available space, and foundation strength. Evaluate thermal capacity for continuous or reversing duty. Specify any custom interfaces or cooling requirements. Review efficiency curves at expected operating loads and confirm compatibility with existing motor and mill stand dimensions.

کوالٹی سرٹیفیکیشن اور سروس کا عزم

All units are manufactured under ISO 9001:2015 quality management and carry CE marking. An 18-month warranty from shipment or 12 months from commissioning (whichever comes first) covers materials and workmanship. Global technical support, spare parts, and on-site commissioning services are available from the Dutch headquarters and authorized partners.

اکثر پوچھے گئے سوالات

Q: What service factor is recommended for rolling mill applications?
A: A minimum service factor of 2.0–2.5 is recommended to account for frequent reversing duty and heavy impact loads.

Q: How is thermal management handled in high-temperature mill environments?
A: Forced lubrication with oil cooling systems and optional external coolers maintain stable operating temperatures up to 120 degrees C ambient.

Q: Can these gearboxes be supplied with condition monitoring?
A: Yes. Standard mounting points allow integration of vibration, temperature, and oil condition sensors for predictive maintenance.

Q: What alignment tolerance is required during installation?
A: Parallel and angular alignment within 0.05 mm is recommended to ensure even load distribution and extended bearing life.

Q: Are spare gear sets readily available?
A: Yes. Critical spare parts including gear sets, bearings, and seals are stocked for rapid dispatch to minimize mill downtime.
