has been tested by commercial production. Results show that with increasing argon flow rate
using pentary slag series and evenly adding Al powder in remelting process
the average loss of titanium content- △ [Ti
]
in remelting ingot could be ≤0. 15%. With using optimized process
filling ratio 0.58
current 12 500 ~ 13 500 A
voltage 40-43 V
pentary slag series
and argon flow rate 30 L/min the results for steel 1Cr21Ni5Ti remelting by 6 t shielding atmosphere ESR unit show that element content in ESR ingot is constant
the C content in ingot is 0.090% -0.091% and Ti content in ingot is 0.46%-0.52% .
