AI Technical Summary
Existing technologies are unable to effectively process composite alloy waste rich in Si, Mn, and Zn elements, resulting in high production costs, low yield, and traditional production methods that cannot meet the requirements of high-temperature brazing.
By using composite brazing waste, optimizing the three-stage rolling process and strictly controlling the rolling temperature of the cast plate, three-pass rolling production is achieved, reducing subsequent processing costs. Aluminum-titanium-boron wire is used for grain refinement, combined with online degassing and filtration, to produce 3003ZNZR alloy billets.
It achieves low-carbon and environmentally friendly production, reduces production costs, improves yield, meets high-temperature brazing performance requirements, and is suitable for key components in automotive heat exchange systems.
