Abstract

The most suitable stirring condition has been investigated on the basis of the mechanism of the decarburization in VOD. Results are summarized as follows: (1) A decarburization model considering each reaction sites as hot spot, free surface, internal, bubble and slag was constructed. As a results, it became possible to quantify the contribution ratio of each reaction site in decarburization rate at each [C] region in VOD. (2) Decarburization rate became larger with increasing stirring energy. And it was larger at a single buyer than double buyers according to the difference of the plume eye area.
