Abstract Scope |
Ellwood Quality Steels operates two ESR furnaces: ESR1 utilizing a 25,000A 60Hz inverter power supply and ESR2 utilizing a 50,000A 2.5Hz cycloconverter power supply. This work examines the differences in melting conditions and ingot quality of 760 mm diameter ESR using 60 Hz versus 2.5 Hz alternating current. Metallurgical comparisons include melt pool depth and shape, microcleanliness, segregation and inclusion distribution. Electrical and physical conditions during melting are compared. |
