Application of Thyristor on Double-Frequency Quenching Machine

The process of thyristor changing work-frequency of electric power into low intermediate frequency was introducd,which were successfully used in Gongchang double frequency(low intermediate frequency) Quenching machine.In contrast with Belgium OSB double frequency(work-intermediate frequency) Quenching machine,Gongchang double frequency(low intermediate frequency) Quenching machine reaches properties of foreign machine;a new homemade path of high-efficiency and low cost is put out.
