Ladle furnace transformers (LF transformers) have relatively lower capacity compared to EAF-type transformers. The transient stresses experienced by LF transformers are also lower than those in EAF transformers. As a result, most LF transformers have a single active part structure and feature variable flux performance. However, the passage of high currents and the variability in their loading cycles necessitate reliable design and production.
In companies that use EAF transformers, LF transformers are often essential for the final refinement of the product and the formation of the final alloy. Ensuring the performance and reliability of LF transformers is crucial for achieving the desired quality in steel production.
