fine oreとは 意味・読み方・使い方

The high-speed stirring makes the contacting area of the fine powdery ore 1 with the charcoal wood 4 large, and gives the partially reduced and sintered ore the high reducing capability.例文帳に追加

高速撹拌にて微粉鉱石１と炭材４の接触面積が大きくなり高還元率の半還元焼結鉱が得られる。 - 特許庁

In granulating the raw materials for sintering having triple-layer structure constituted by forming a fine-ore layer on the surface of core ore and further forming a mixture layer of powdery carbonaceous material and limestone fines on the surface of the fine-ore layer, limestone fines containing ≥50 mass% fine limestone of ≤0.5 mm particle size are used.例文帳に追加

核鉱石の表面に微細鉱石層を形成し、さらに微細鉱石層の表面に粉状炭材と粉石灰石との混合層を形成してなる３層構造の焼結原料を造粒するにあたって、粒径0.5mm 以下の微細石灰石を50質量％以上含有する粉石灰石を使用する。 - 特許庁

The melting temperature of the fused ore, assimilating the fine powdery ore with the action of FeO source, is lowered, and since the fluidity of the fused ore is enhanced, the formation of difficult gas permeability layer on the sintering bed is restrained.例文帳に追加

上記ＦｅＯ源の作用により微粉鉱石を同化する融液の溶融温度が低下し、融液の流動性が高められるため、焼結ベッド内での難通気性層の形成が抑制される。 - 特許庁

To provide a method of producing sintered ore where productivity and the yield of products are not reduced even when maramanba ore of high crystallization water and low gangue containing much fine powder is used as the raw material for sintered ore.例文帳に追加

高結晶水・低脈石で微粉を多く含有するマラマンバ鉱石を焼結鉱原料として使用しても、生産性や製品歩留りを悪化させることがない焼結鉱の製造方法を提供する。 - 特許庁

In the methods (1) or (2) for producing the sintered ore, it is preferable to selectively use a coarse grain portion in the return ore which has been classified into the coarse grain portion and a fine grain portion, as the return ore to be added after the granulation.例文帳に追加

前記（１）または（２）の焼結鉱の製造方法において、造粒後に添加する返鉱として、粗粒部分と細粒部分とに分級された返鉱のうちの粗粒部分を選択的に用いることが好ましい。 - 特許庁

Further one of charcoal, bamboo coal, ore fine powder and a plant nutrient is added thereto.例文帳に追加

さらに、これらに木炭・竹炭・鉱石微粉末・植物栄養剤のいずれかを加える。 - 特許庁

In the sintering process, since a large quantity of fused materials are generated surrounding iron ore A having many fine pores, a part of the fused material is absorbed into the fine pores, but the remaining fused material is served as a function of bond for combining between the ore grains and the cold strength of the sintered ore is made to be high.例文帳に追加

焼結過程において、微細気孔が多い鉄鉱石Ａの周囲に多量の融液が生成するため、微細気孔内に融液の一部が吸収されても、残余の融液が鉱石粒子間を結合するボンドの機能を果し、焼結鉱の冷間強度が高められる。 - 特許庁

A fine powder of uranium or radium, a fine powder of a mineral ore containing the radium or the like can be used as the material generating the α-ray or the γ-ray.例文帳に追加

α線又はγ線発生物質として、ウラニウム、ラジウムの微粉末又はラジウムを含有するミネラル鉱石の微粉末等を使用する。 - 特許庁
