Abstract

A model for energy equilibrium in melting process of vacuum induction melting and the rational electric power supply regulation in each melting period have been derived and got by systematical analysis and calculation on power requirement and loss in melting process of 3 - 6 t vacuum induction furnace and on basis of electro- thermal equilibrium law of system. Hie results of melting 38 heats steel 300M (0.4C

1.64Si

0.29Co

1.85Ni

0.4Mo) in 3 ~ 6 t vacuum induction furnace showed that after using optimum electric power supply regulation the electric consumption decreased by 41 kWh/t

the productivity increased by 8.3%

Mn and Cr yield increased by 1.6% and 0.25% respectively

and the service life of crucible increased obviously.
