Zusammenfassung:To provide a technology for easily applying a pre-desulfurization treatment or an additional desulfurization treatment to hot metal.SOLUTION: A desulfurizer wire feeding device includes a wire drum holding part for holding a wire drum in which a desulfurizer wire is wound in a coil shape, a wire feeding part for drawing out the desulfurizer wire from the wire drum holding part and feeding the desulfurizer wire toward hot metal filled in a hot metal ladle, and a wire guide part for guiding the desulfurizer wire fed from the wire feeding part and feeding the desulfurizer wire toward the hot metal bath surface filled in the hot metal ladle. In a hot metal desulfurization facility, the desulfurizer wire feeding device is adjacent to a slag removing device having a slag removing function for scraping out slag in the hot metal ladle to the outside of the hot metal ladle in a state of tilting the hot metal ladle and a dust collecting function for collecting dust generated during the slag removing operation. The slag removing device is arranged movably in a direction parallel to the direction of scraping out the slag.SELECTED DRAWING: Figure 1 【課題】容易に事前脱硫処理や追加脱硫処理を溶銑に施すことができる技術を提供する。【解決手段】脱硫剤ワイヤーをコイル状に巻き付けたワイヤードラムを保持するワイヤードラム保持部と、ワイヤードラム保持部から脱硫剤ワイヤーを引き出して溶銑鍋に充填された溶銑に向けて送給するワイヤー送給部と、ワイヤー送給部から送給された脱硫剤ワイヤーを案内し、溶銑鍋に充填された溶銑浴面に向けて送入するワイヤー案内部と、を備える脱硫剤ワイヤー送入装置を設け、さらに該脱硫剤ワイヤー送入装置は、溶銑鍋を傾動させた状態で該溶銑鍋内のスラグを溶銑鍋外に掻き出す除滓作業を行なう除滓機能と、除滓作業中に発生するダストを集塵する集塵機能と、を備える除滓装置に隣接し、除滓装置がスラグを掻き出す方向に平行な方向に移動可能に配設されている溶銑脱硫設備である。【選択図】図1
