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。

Coal agglomeration in blast furnace injection coals [PDF]
In order to reduce expensive coke usage, blast furnace operators inject coal to replace a portion of the coke. However, the use of some injection coals can result in blast furnace instability and lowered permeability. This thesis is concerned with the

Barriers to Steel Decarbonization
steel research international, EarlyView.Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

steel research international, EarlyView.This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.
