rimmed steelとは 意味・読み方・使い方

The smelting method is an improved method of smelting the aluminum-deoxidization steel and includes the steps of subjecting the molten steel to the rimmed deoxidization treatment of making a molten steel tapped out from a converter react with carbon and oxygen in the molten steel under a reduced pressure in a vacuum degassing apparatus, and further subjecting the molten steel to killed deoxidization treatment by adding aluminum to the molten steel.例文帳に追加

転炉から出鋼した溶鋼を真空脱ガス装置にて、減圧下で該溶鋼中の炭素と酸素とを反応させてリムド脱酸処理してから、さらにアルミニウムを添加してキルド脱酸処理するアルミ脱酸鋼の溶製方法を改良した。 - 特許庁

To provide a method for vacuum-decarburizing a molten steel, which can appropriately shift decarburization by blowing an oxygen gas to rimmed decarburization even without previously determining an oxygen quantity to be sent, and decarburize the molten steel accurately into a targeted value even in an extra low carbon region.例文帳に追加

事前に送酸量を定めずとも、酸素ガスの吹き付けによる脱炭からリムド脱炭への移行を適切に行え、極低炭素領域であっても目標達成精度良く脱炭が可能な溶鋼の真空脱炭方法を提供する。 - 特許庁
