With the simulation on the composition of converter steelmaking slags, the experiments of hot metal pretreatment by using CaO-SiO2-Fe2O3-MnO2-MgO-P2O5-Al2O3-CaF2 fluxes were performed in the laboratory scale. The results showed that the desiliconization rate of about 75 % and the dephosphorization rate of 80 % are achieved by using converter slags...

The experiments of rephosphorization controlling by using Li2O, Na2O, K2O, BaO instead of part of CaO in CaO-based fluxes were performed at 1 853 K in laboratory scale. The results indicated that thg dephosphorization ability of fluxes by adding different agents was decreased in following order: Li2O>Na2O>K2O>BaO. Using Li2O as adding agent to CaO-...

The effect of oxygen potential on De-Si and De-P, and initial [Si] content on De-P during hot metal pretreatment were studied by Fe2O3-CaO-CaF2 slag. The results showed that the final [Si] content of 0.144 %-0. 090 % can be reached if the oxygen potential is controlled in the range 1. 64×10-4% to 3. 26×10-4%; when initial [Si] content in hot metal...

... Because no additional oxygen gas is injected during the tapping of BOF, and the low contents of dissolved elements may influence the slag formation when dephosphorisation. Although few earlier studies [2][3][4][5][6]23,29] were carried out to investigate the interaction between CaO-based flux and BOF crude steel, the dephosphorisation behaviours (especially interface behaviours) during tapping are still not clearly understood. Further mechanism studies are needed focusing on the interface behaviours of dephosphorisation during tapping. ...
