| 摘 要： | 基于转炉炼钢过程脱磷的热力学分析和计算，以控制转炉冶炼过程脱磷期温度为出发点，提出一种利用CO2气体代替部分O2进行吹炼的转炉炼钢新工艺，即COMI炼钢工艺。研究发现：COMI炼钢工艺能有效控制转炉熔池温度，降低半钢和一倒钢液磷含量，同时可有效减少炉渣铁损，为转炉高效脱磷提供了一种新思路。

| Abstract: | Based on thermodynamic analysis and calculation of dephosphorization in converter steelmaking process,COMI steelmaking process,in which CO2 was used as a substitute for part O2 to control the temperature of dephosphorization,was presented.It is discovered that the bath temperature can be effectively controlled and phosphorus content of liquid steel is reduced by COMI steelmaking process.Moreover,iron losses of slag are lowered.The process will provide a new idea of converter dephosphorization with high effi... |
