Study on Slag Forming Route of Dephosphorization in Combined Blown Converter

نویسندگان

چکیده

In order to achieve the purpose of high-efficiency dephosphorization by single-slag method during combined blown converter steelmaking process, CaO-SiO2-FetO-MgO-MnO-P2O5 slag system was taken as research object, and slag-forming route studied. The effects compositions on liquidus contour map phosphorus distribution ratios (recorded Lp) were calculated thermodynamics software FactSage, then theoretic obtained. rate Lp studied a high-temperature experiment. Based results calculation experiment, actual process in obtained: initial composition should be around 15.0%CaO-44.0%SiO2-41.0%FetO. 50.8%CaO-24.2%SiO2-25%FetO. final 65.6%CaO-28.3%SiO2-6.1%FetO. After using production, increased 3.6%, consumption slagging materials reduced 3.78 kg/t.

Role of Surface Phenomena on Converter Slag Composition

For beneficiation of converter slag, the role of surface phenomena on slag composition was studied. This work includes some experimental data, which were measured for basic oxygen steel (BOS) slag in Isfahan Steel Plant. All data were collected on site in the plant. The results support the idea that surface activity plays a major role in converter slag formation. It was also a new finding t...

Recovery of Manganese and Phosphorus from Dephosphorization Slag with Wet Magnetic Separation

The dephosphorization slag has a great potential as the secondary resources of manganese and phosphorus, while quite a large amount of slag is landfilled and simply reused such as cement. The objective of this study is to investigate the recovery of manganese and phosphorus by wet magnetic separation technique. The hot metal pretreatment slag (dephosphorization slag) generally contains a Ca3P2O...
