The basic ladle design can therefore include many variations that improve the usage of the ladle for specific tasks. For example: Casting ladle: a ladle used to pour molten metal into moulds to produce the casting. Transfer ladle: a ladle used to transfer a large amount of molten metal from one process to another. Typically a transfer ladle ...
One ladle is in the 'on-cast' position (feeding the casting machine) while the other is made ready in the 'off-cast' position, and is switched to the casting position when the first ladle is empty. From the ladle, the hot metal is transferred via a refractory shroud (pipe) to a holding bath called a tundish. The tundish allows a reservoir of ...
A ladle of hot metal is poured in an archival photo taken at a former ESCO foundry in Portland, Ore. ESCO was founded in 1913 by Oregon businessman Charles (C.F.) Swigert as a local source of steel castings. The Electric Steel Foundry Company was founded on property once occupied by the 1905 Lewis and Clark Centennial Exposition.
Oakum and tools for caulking Hemp Prisoners picking oakum at Coldbath Fields Prison in London. Oakum is a preparation of tarred fibers used to seal gaps. Its traditional application was in shipbuilding for caulking or packing the joints of timbers in wooden vessels and the deck planking of iron and steel ships. [1]
The ladle is used for the first purpose when there is a delay later in the steelmaking process. The ladle furnace consists of a refractory roof, a heating system, and, when applicable, a provision for injecting argon gas into the bottom of the melt for stirring.
Ladle operations include de-oxidation (or "killing"), vacuum degassing, alloy addition, inclusion removal, inclusion chemistry modification, de-sulphurisation, and homogenisation. It is common to perform ladle operations in gas-stirred ladles with electric arc heating in the furnace lid.
The Gary Works is a major steel mill in Gary, Indiana, on the shore of Lake Michigan.For many years, the Gary Works was the world's largest steel mill, and it remains the largest integrated mill in North America. [1]
In metal casting, a tundish is a broad, open container with one or more holes in the bottom.It is used to feed molten metal into an ingot mould to avoid splashing and give a smoother flow.
