Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking
steel research international, EarlyView.Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=

steel research international, EarlyView.Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Journal of the Fuel Society of Japan, 1952 製鉄工業は予期以上の回復を見せ, 現有設備の全能力を発揮する必要が遠からず起るものと期待される。この場合銑鉄生産は年間500万t, これに必要なコークス用炭は770万tとなる。熔鉱炉操業を技術的且つ経済的に検討すると, コークスとしては高い強度, 低い灰分及び優れた化学的性質が必要である。鉱石の整備により強度への要求は稍緩和されたが, なお306万tの外国産強粘結炭が必要となろう。コークス品位の改善方策として, 原料炭の洗炭と粉碎, 外国産張粘結炭の配合及び半成コークス, 粉コークスその他の配合が実施又は研究されており, 我々が現在又は將来手近に持つものから必要なコークスを作り出すことが期待される。
