Ladle metallurgy has its origins in vacuum technology. As early as in the 19 th century, it was known that gases dissolved in the steel were responsible for diverse casting flaws. The first suggestions to apply a negative pressure to the molten steel go back to this period; at the same time, the use of argon as a bubbling gas was contemplated. However, it was not until around 1950 that such ...

Ladle (metallurgy) - Wikipedia

In metallurgy, a ladle is a vessel used to transport and pour out molten metals. Ladles are often used in foundries and range in size from small hand carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (330 tons). Many non-ferrous foundries also use ceramic crucibles for transporting and pouring molten metal and will ...
