Fire lanceとは 意味・読み方・使い方

Previous firearms were types where live coals (matches and so on) were pushed down by hands (a touch-hole type) ('flame-spurting lance' - a bamboo gun in the Sung dynasty, 'a fire lance' [a gunpowder weapon] in the Ming dynasty, 'madfa' in Russia around 1300 and so on) which was difficult to handle, and the firing accuracy was low.発音を聞く 例文帳に追加

それ以前の銃器は、火種（火縄など）を手で押し付ける方式（タッチホール式）であった（宋(王朝)の「突火槍」、明の「火竜槍」、1300年頃のロシアの「マドファ」など）ことから、扱いが難しく命中精度も低かった。 - Wikipedia日英京都関連文書対訳コーパス

In a converter lance, a center hole and six positions of peripheral holes having the inclination, are disposed and a distance between the fire point and the refractory is made to ≥0.4 m and while making ≤30% of the overlapping ratio in the fire points, the total area ratio of the fire point is made to ≥75%.例文帳に追加

転炉ランスに、中心孔と、傾斜を持つ６カ所の周囲孔を設置し、火点と耐火物の距離を０．４ｍ以上とし、火点のオーバーラップ率を３０％以下としつつ、火点最外周円内における火点の総面積率を７５％以上とする。 - 特許庁

To effectively add a refining agent to a fire location in a reaction zone while restraining the scattering of the refining agent when oxidation refining to molten iron is performed by blowing oxygen-containing gas and the powdery refining agent to the molten iron from a top-blown lance.例文帳に追加

酸素含有ガス並びに粉体の精錬剤を上吹きランスから溶銑に吹き付けて溶銑を酸化精錬するに当たり、精錬剤の散逸を抑制して精錬剤を反応領域の火点へ効率的に添加する。 - 特許庁

Water is mixed into the oxygen gas for top-blown lance in the converter and a fire point at ordinarily high temperature is cooled and vapor pressure in metal content is lowered to restrain the development of the dust.例文帳に追加

転炉の上吹きランスの酸素に水を混合して通常高温である火点を冷却して、メタル分の蒸気圧を低下させてダスト発生を抑制する。 - 特許庁
