The roughing gearbox is a vital component in hot steel rolling lines, responsible for providing the necessary torque for the rolling operation during the roughing stage. This gearbox converts rotational speed into high torque, supplying the force required to reduce the thickness and perform the initial shaping of the product.

Structural and Functional Features:
1-Gear Ratio: This gearbox is designed and manufactured with a gear ratio of 1:12. This ratio means it reduces the input rotational speed by 12 times while significantly increasing the output torque. This enables the rolling rolls to overcome the material's resistance at high temperatures.
2-Housing and Gears: The gearbox housing is made from robust steel to withstand the vibrations and extreme pressures of the industrial environment. Additionally, the gears are produced from high-quality materials, ensuring their durability and long-term performance.
3-Manufacturing Precision: All machining processes for this gearbox are carried out using CNC (Computer Numerical Control) machines. This process ensures the highest possible machining precision, which in turn guarantees optimal performance and reduced vibration and noise during operation.

In summary, the roughing gearbox, with its durable design and high manufacturing precision, plays a fundamental role in transmitting motive force to the rolling rolls and completing the initial shaping process in the steel industry.
