In this challenge, you will be able to follow the request of the client, a major national player in the hydroelectric power sector, as well as follow the solutions provided by the Torres team under the client's supervision, resulting in a product with specifications that technically met the project requirements.
The challenge
Aços Torres specializes in projects that require engineering for customized products. The challenge you are about to see involved the participation of the company's Production Engineering, Commercial, and Operations departments, as well as the constant participation and supervision of the customer.
After all, more than just a simple damping system, it was the damping of large hydroelectric turbines.
The customer's request
Manufacture the final product with the following characteristics:
Develop heat treatment to ensure mechanical properties.
Perform final machining for the established geometry.
The product
The product development had to meet mechanical and microstructural requirements.
Looking at the mechanical requirements, it can be seen that the flow and tensile properties are high, and that triaxial forging and heat treatment would necessarily be the differentiators for meeting the requirements.
Furthermore, grain alignment was necessary for the product to function properly, as the part in question would bear heavy loads and act as a spring, absorbing vibrations from the equipment.
Design of the ideal forging tool and blank
Calculations and development
Forging simulation
Heat Treatment Grinding
Heat Treatment
After evaluating the microstructure characteristics, steel properties, and empirical data, we directed the heat treatment toward controlled cooling, achieving success in mechanical properties with less geometric distortion.
Final machining
The final machining process was designed as an initial in-line turning process followed by face grinding to achieve productivity and repeatability.
With this integrated process between the customer, sales department, engineering, and production, Aços Torres was able to deliver a new part that was 100% customized to meet all specifications and requirements.
