Meeting the Heavy-Duty Challenges of the Steel Industry

The steel industry stands out as a major user of gearboxes and gear reducers due to the sheer scale and intensity of its machinery. Steel manufacturing requires heavy-duty machinery that can provide precise control over speed and power transmission. Gearboxes play a crucial role in adjusting and maintaining the rotational speed and torque, enabling the accurate and efficient production of various steel products such as sheets, bars, beams and tube foaming.

TIEN YI has extensive experience in designing and manufacturing all types of gears and gearboxes used in various steel rolling process, cutting, and forming machines. We offer reliable solutions that meet the high requirements and extreme working conditions of the steel industry.

Gearbox Applications and Quality Requirements

Various applications of gearboxes in steel industry machinery include:

  • Rolling Mills: Gearboxes are essential in steel rolling mills to control the speed and torque of the rolls that shape and form steel into sheets, bars, and beams. TIEN YI gearboxes are capable of accurately controlling the high torque loads generated during heavy-duty rolling operations performed with mill drives, levelers, bridal drives, coilers, and tube forming machines.
  • Steel Cutting Equipment: Gearboxes are used in steel-cutting shears and saws to control the cutting speed and force. High-quality gears provide precise speed control in shear drives to ensure accurate and consistent cuts.
  • Conveyor Systems: Gearboxes in conveyor systems and elevators control the consistent transport of raw materials, semi-finished products, and finished steel products throughout the production process.
  • Forging Presses: Robust gearboxes are capable of handling the exceptionally heavy forces placed on forging presses used in high-pressure forming operations.

In all applications, gearboxes must be robust and reliable. Efficient cooling and lubrication effectively dissipate heat and ensure smooth operation over extended periods. Low noise and vibration create a safer and more comfortable working environment, while a compact design optimizes space utilization.

Gear Couplings 

Gear couplings are devices used to connect two rotating shafts, transmit power and torque, and allow for bending and misalignment of the two shafts. Industrial gear couplings are known for their ability to handle high torque transmission and are particularly valuable in heavy-duty applications, such as steel manufacturing, where large machinery and equipment are employed to handle substantial loads.

High-Speed Applications

Steel manufacturing processes often require high rotational speeds. Gear couplings are capable of transmitting torque efficiently at high speeds. They are extremely durability and can withstand extreme temperatures, harsh environments, and heavy loads while operating at high rotational speeds. 

The design of gear couplings facilitates easy maintenance and inspection, enabling quick component replacement if necessary. Moreover, these couplings offer additional safety benefits and are less likely to experience severe failures.

Universal Joints

Universal joints are commonly used in power transmission industries, where they play a vital role in transmitting rotational motion and torque between shafts at various angles. They enable smooth power transfer while accommodating misalignments during transmission, facilitating the balance of suspension systems.


 A universal joint is a mechanical transmission device that can transmit torque and motion at different angles and directions. It has the following characteristics:

  • Large-angle transmission: 15-25°.
  • High operating smoothness.
  • Suitable for high speed.
  • Easy maintenance and installation.
  • Widespread application.

Solutions for power transmission:

  • Rubber and plastics (calendar, mixer & banbury machinery).
  • Steel (rolling mills).
  • Paper making.
  • Others (transportation, and related industries).
