special pig ironとは 意味・読み方・使い方

To provide a method for manufacturing a low-phosphorus molten pig iron, which can effectively promote melting of smelting materials, and efficiently manufacture the low-phosphorus molten pig iron at a low cost, without using any special facility or an expensive melting accelerator, in dephosphorizing treatment for pretreatment of the pig iron.例文帳に追加

溶銑の予備処理として行われる脱燐処理において、特別な設備や高価な溶融促進剤を用いることなく精錬材の溶融を効果的に促進し、低燐溶銑を効率的且つ安価に製造することができる低燐溶銑の製造方法を提供する。 - 特許庁

To provide a method for manufacturing a raw material for fertilizer, which can reutilize a large quantity of generated slag in a molten pig-iron pretreatment process, for the raw material of fertilizer such as a raw material for fertilizer of phosphoric acid base obtained from slag after dephosphorization, and a raw material for a potash fertilizer of silicic acid base which is obtained from slag after desiliconization, without adding a special process.例文帳に追加

特別な工程を付加することなく脱燐スラグから燐酸質肥料用原料を得ることができ且つ脱珪スラグからも珪酸質カリ肥料用原料を得るなど、溶銑予備処理工程で発生する大量のスラグを肥料用原料として利材化することができる肥料用原料の製造方法を提供する。 - 特許庁
