The production flowsheet for MA ultra-low carbon steel (/% : ≤0.005C
0.007-0.012Si
0.07-0.15Mn
≤0.025P
≤0.025S
≤0.035Als
≤0.0020N) is KB-150 t BOF (end [C
]
≤0.020%)-RH-200 mm slab CC flowsheet. The effect of mold flux
tundish shielding agent and ladle refractory materials on incremental carbon content in liquid has been tested and analyzed. Results show that the incremental carbon content in liquid in mold ( AC 0.0003%-0.0008% ) is obviously higher that in tundish (AC 0.0001%-0.0005% )
through using the measures including defining metallurgy operation
controlling initial carbon content in mold flux 1% -2% and adding 3.5%-4.0% MnO

in flux
controlling the amount of tundish shielding agent
it is available to decrease the incremental carbon content in liquid.
