The development history of electroslag remelting ( ESR) commercial production for 50 years is reviewed briefly
and the presentation and evaluation of new technology of ESR metallurgy in recent years are focused including electroslag rapid remelting
double electrode series electroslag continuous casting technology
ultra-heavy slab ingot ESR
technology for solidification segregation control of heavy ESR ingot
ESR furnace with controlled atmosphere and ESR casting technology with liquid metal. It is indicated that in new development phase the ESR metallurgical technology is developed with high efficiency
saving energy
environmental protection and meeting requirement for higher quality.
