The value of slag resistance in ESR stable melting condition with different electrode immersing depth is obtained by simulation using MHD ( magneto-hydrodynamics) module of Software Fluent
and the mathematical model of electrode immersing depth is established by relating slag resistance with electric power scheme. In condition of ESR stable smelting of 2.3t ingot at special steelwork
the model calculated value of electrode immersing depth is 14.4mm
as compared with situ measured value 14mm
the relative error is small. With the present electric power scheme- 58V and 9000A for bearing steel G20CrNi2Mo
the minimum slag amount for maintaining normal remelting is 24.3kg/t; the reasonable process for 2.3t ESR ingot is voltage 58V
current 9000A
slag amount 30kg/t and electrode immersing depth 14.4mm.
