Abstract
The distribution of metal particles in a slag is studied during argon blowing of steel in a ladle. It is established that the fraction of the metallic phase in the top slag layer is 3.5–5 times smaller than that in the middle and bottom layers. A microscopic analysis of the fraction composition and the geometric shape of the metallic particles show that all portions of the slag part of samples contain significantly larger amounts (by a factor of approximately 4–5) of irregular plane particles along with fine spherical particles.
