A study was madeon the mechanism of dust generation by investigation of dust behavior in a BOF with combinedblowing.The results are summarized as follows:(1 )BOFdust is generated through "fumes" condensing and mixing with "burst bubble particles". (2)

SynopsisA study has been made to clarify the mechanism of post combustion on the basis of the hot metal experiment by the use of a 250-t converter and an 02-CO experimental combustion furnace and of the results of the decarburization experiment with a 10-t ladle.The post combustion ratio " a " observed is well explained by the post combustion model presented in this report. The equations derived for the estimation of the post combustion ratio are as follows.((S,,1F02, +J3J,Fo2J = 0 (-1
