The molten steel produced in various steelmaking furnaces is first poured into a ladle, then poured into a mold (ingot case) and solidified to produce ingots. The ladle has a nozzle at the bottom through which the molten steel flows, and is designed to be able to open and close. There are two methods for pouring molten steel: top pouring, in which it is poured from above the mold, and bottom pouring, in which it is poured from below the mold through a refractory runner. The bottom pouring method is generally used when the quality of the ingot is important. The weight of an ingot is usually 5 to 50 tons for normal carbon steel, but some can weigh over 500 tons.

各種の製鋼炉でつくられた溶融状態の鋼をいったん取鍋(とりなべ)に受けた後,鋳型(インゴット・ケース)に注入し,凝固させてインゴットをつくること。取鍋は底部に溶鋼を流出する湯口(ノズル)があり,開閉できる構造になっている。溶鋼の注入法には,鋳型の上方から注入する上注法と,耐火物の湯道を通して鋳型の下方から注入する下注法がある。インゴットの品質を重視するときは,一般に下注法を用いる。インゴットの重量は通常の炭素鋼では5~50tであるが,500tを超えるものもある。
