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

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% .
