このような溶銑の試料採取は、従来においては、高炉鋳
床の主樋で銑滓分離した彼の溶銑の流れの一部を作業者
が試料採取棒を用いて行なっていた。Generally, pig iron tapped from a blast furnace contains C+ SbMn.
, P, S, etc.
In the steelmaking process, it is necessary to adjust these components. To do this, it is necessary to understand each component in the pig iron in advance, and a sample of the pig iron must be collected and analyzed. - Conventionally, such sampling of hot metal was carried out by an operator using a sampling rod in a part of the stream of hot metal that had been separated from the pig iron slag in the main trough of the blast furnace casthouse.
しかしながら、この方法においては、 （１）高熱、塵埃のため作業埋填゛が悪い。However, in this method, (1) Poor work filling due to high heat and dust.
（２）高炉よりの一回の出銑においても、その出銑成分
は刻々と変化しており、溶銑流の−１＜ＩＸの試料採取
では、全体の平均した溶銑成分と０：なら々い。(2) Even in a single tap of iron from a blast furnace, the tapped iron composition changes from moment to moment, and when sampling hot metal flow at -1 < IX, the overall average hot metal composition and 0: are about the same. .
（３）溶銑鍋（混銑車）Ｋは平均約２０ （ｏｎの溶銑
が残銑とＬ〜て残留しているので製鋼前１ｉ１２分と出
銑成分が異なる。(3) The hot metal ladle (mixing car) K is about 20 (on) on average and the hot metal remaining in the residual pig iron L~, so the tapped iron component is different from 1i12 min before steel making.
（４）溶銑樋で溶銑予備処理をｒｉ／ｒうと、出銑成分
と製鋼前成分とが異々る。(4) When hot metal pretreatment is carried out in a hot metal sluice, the tapping components and the pre-steelmaking components are different.
