    5吨中频炼钢炉的变压器配置


      中频炼钢炉与其他设备在配置变压器上是不同的,电能是中频炼钢炉的心脏,中频炼钢炉在冶炼过程中瞬间电流大、波动大要求变压器为专用变压器。
       选择低损耗的变压器,中频炼钢炉使用高负荷时间长,变压器自身的损耗直接影响了吨耗电量。

    Transformer configuration of 5 ton intermediate frequency steelmaking furnace

      Intermediate frequency steelmaking furnace is different from other equipment in the configuration of transformers. Electricity is the heart of the intermediate frequency steelmaking furnace. The instantaneous current and large fluctuations of the intermediate frequency steelmaking furnace during the smelting process require the transformer to be a special transformer.

       Choose low-loss transformers. The medium-frequency steelmaking furnace uses high load for a long time, and the transformer's own loss directly affects the power consumption per ton.
