摘要：

A large-scaled induction furnace for nonferrous metal billets is operated with commercial frequency, and it does not have such high energy efficiency of 50%-60% due to the considerable energy loss of copper coils to generate magnetic fields. Despite the additional efforts to improve the efficiency, it has limitation to increase it, physically. In this paper, a design specification for a 300-kWHTS dc induction furnace (HTS DC IF) was presented, and the characteristic analysis of the sample HTS magnet was conducted. The characteristic resistance, the charging and the discharging time were calculated and measured. Detailed investigations of the sample model on voltage characteristics of ten voltage taps and temperature characteristics were conducted. The test results will be applied to the full-scale HTS DC IF.
