Abstract
In the 300 t dephosphorization converter, the bottom-blowing O2–CO2–CaO technology has been developed and a range of tests executed to optimize the top-blowing parameters. A comprehensive analysis has been carried out on the effects of “tapping temperature T”, “slag basicity R” and “slag T.Fe content” on the end-point P content, based on data gathered from nearly 2000 smelting operations, using single-factor analysis. Optimal thermodynamic conditions for dephosphorization were obtained, with a tapping temperature of T: 1290–1310 °C, slag basicity of R > 1.3, slag T, Fe content of 5–10%. The results indicate that dephosphorization rates have increased by nearly 12% under such conditions compared to the original process.
