Process for Production of Ultra-Low Sulphur Steel by BOF Tapping Desulphurizing-LF Refining

Because the sulphur content in steel NVA32(0. 12~0. 18C,1.30～1.60Mn)increases to 0.020% at 210 t BOF melting end point from original 0.005%,it shall be added 1000 kg binary synthetic slag CaO-CaF₂ and added  200 kg aluminium during BOF tapping and added Si-Mn alloy and Si-Al-Ba alloy to decrease sul...
