The Mechanism of Post Combustion in Converter

Abstract

A study has been made on the mechanism of post combustion by the hot metal experiment using 250 t converter and O2-CO experimental combustion furnace. In addition to these experiments, the decarburization experiment has been pursued using 10 t ladle.Post combustion ratio "α" observed is well explained by the post combustion model presented in this report. The equations to estimate post combustion ratio are as follows.αi≅ 0.1 ( h/d0 )0.3-(h/d0)-0.7+0.01α= Σij(αi × βij × FO2i) / ΣiFO2i(βijFO2i+βjiFO2j = 0 (-1 ≤ βij≤ 1 ))
