blast oとは 意味・読み方・使い方

To provide a method for operating a blast furnace with which the ratio of O/C(ore/coke) at the center part can be raised without lowering the O/C ratio at the peripheral part by effectively restraining the collapse of the coke in the bell-type blast furnace.例文帳に追加

ベル式高炉においてコークス崩れを効果的に抑制して周辺部のＯ／Ｃを低くすることなく中心部のＯ／Ｃを上げることができる高炉操業方法を提供する。 - 特許庁

To provide a charging method in which a good V-shaped fusing zone having a high center part in a blast furnace without hanging down from a intermediate part to the peripheral part in the blast furnace in a high O/C operation.例文帳に追加

高Ｏ／Ｃ操業において、炉中心部が高く且つ炉中間部から周辺部の垂れ下がりのない良好なＶ型の融着帯形状を制御できる装入方法を提供する。 - 特許庁

To achieve the lowering of fuel ratio and the improvement of production in a blast furnace by securing the reducibility of a sintered ore, raising an O/C ratio at the peripheral part of the furnace and improving the reducing efficiency in this zone when a large quantity of pulverized fine coal is blown in.例文帳に追加

微粉炭多量吹込み時に焼結鉱の被還元性を確保し、炉周辺部のＯ／Ｃを上昇させ、この領域の還元効率を向上させることにより、高炉の燃料比低減、生産性向上を達成する。 - 特許庁

To achieve the improvement of productivity and the lowering of fuel ratio in a blast furnace by securing the reducibility of a sintered ore when Al2O3 content in the sintered ore is high, raising an O/C ratio at the peripheral part of the furnace when a large quantity of pulverized fine coal is blown in, and improving the reducing efficiency in this zone.例文帳に追加

焼結鉱中のアルミナ（Ａｌ2 Ｏ3 ）含有量が高くなったときに、焼結鉱の被還元性を確保し、微粉炭多量吹込み時に炉周辺部のＯ／Ｃを上昇させ、この領域の還元効率を向上させることにより、高炉の生産性向上、燃料比低下を達成する。 - 特許庁

To reduce the fuel ratio of a blast furnace and to improve its productivity, by securing the air permeability and reducibility of a cohesion zone formed by sintered are when a large amount of pulverized coal is flown into the furnace, increasing O/C(ore-to-coke ratio) in the peripheral part of the furnace and improving the reducing efficiency of the same region.例文帳に追加

微粉炭多量吹込み時に、焼結鉱で形成される融着帯の通気性、還元性を確保し、炉周辺部のＯ／Ｃを上昇させ、この領域の還元効率を向上させることにより、高炉の燃料比低減、生産性向上を達成する。 - 特許庁
