The reaction rate was increased and the final carbon content was decreased with the increase in the snorkel diameter and the cross-sectional area of the vacuum vessel, and with the decrease in the amount of molten steel. The maximum decarburization rate and a minimum final carbon content to less than 10 ppm were attained with the largest vacuum vessel whose inner diameter was 1.0m and the cross-sectional area was 5.1m<SUP>2</SUP>. The relation between the final carbon content and the initial decarburization rate was found quantitatively in the experiment.<BR>The experimental results agreed well with calculated values on the
