150t转炉利用炉气分析进行喷溅预报及控制

SLOPPING PREDICTION AND CONTROL ON 150 t BOF BY OFF-GAS ANALYSIS

利用炉气分析对转炉喷溅及控制进行了研究。结论表明 ,在转炉冶炼期间 ,炉气成分中的 CO、CO2 和 N2呈现有规律的变化 ,这些变化规律间接反映了炉渣的状况 ;Os曲线能有效地反映冶炼过程化学反应的进行状况 ;利用 d C/ d O和 Os

The first in China imported off-gas analysis system on 150 t BOF of Benxi Steel is presented, and slopping prediction and control by off-gas analysis has been studied. The conclusions are: CO,CO 2 and N 2 contents in off-gas change regularly during blowing, reflecting the change in slag indirectly; O s is an effective index representing the progress of reaction in BOF, and it is effective for prediction and control of slopping and abnormality with dC/dO and O s model.
