Abstract(J)自動車へのハイテン適用による軽量化でCO2削減に貢献しているが、カーボンニュートラルのためには鉄鋼材料自体の製造時のCO2削減が必要。このための鉄鉱石還元の様々なプロセス革新(水素吹込み高炉:COURSE50、カーボンリサイクル高炉、直接還元法)や、電炉法によるスクラップリサイクルについて紹介する。

Abstract(E)The application of high-strength steel to automobiles contributes to reducing CO2 emissions by reducing their weight, but in order to achieve carbon neutrality, it is necessary to reduce CO2 emissions during the manufacturing of the steel materials themselves. To this end, we will introduce various process innovations for iron ore reduction (hydrogen injection blast furnace: COURSE50, carbon recycling blast furnace, direct reduction method) and scrap recycling using the electric furnace method.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
