ívújraolvasztás

Ivújraolvasztás is a Hungarian term that translates to "re-melting" or "refusion" in English. It refers to the process of melting and solidifying a substance, typically a metal or alloy, multiple times. This can be done for various purposes depending on the material and the desired outcome.

In metallurgy, ivújraolvasztás might be employed to refine metals, removing impurities through selective vaporization or slag formation during the remelting process. Repeated melting and solidification can also alter the microstructure of an alloy, potentially improving its mechanical properties such as strength or ductility. For some materials, controlling the cooling rate after remelting is crucial for achieving specific crystalline structures.

The term can also be used in a more general sense to describe the act of melting something down again after it has already solidified. This might occur in industrial recycling processes for materials like glass or plastics, where they are melted and reformed into new products. The concept of ivújraolvasztás highlights the cyclical nature of material processing and the potential for reprocessing and repurposing.
