for 1. 2 t ESR ingot remelting in normal atmospheric gas the average titanium burning rate is 48. 33%

and for 5. 0 t ESR ingot remelting in argon shielding atmosphere the average titanium burning rate is 2. 61%; while remelting in 5. 0 t ESR f

also with using same steel grade bottom pad and solid slag igniting the phenomenon of picking up carbon in bottom of ingot is obviously improved.
