cast iron Explained

cast iron at English => English (Longman) Of Explained:

n [U] a type of iron that is hard, breaks easily, and is shaped in a mould//

cast iron at English => English (The Britannica Concise) Of Explained:

Alloy of iron that contains 2-4% carbon, along with silicon, manganese, and impurities. It is made by reducing iron ore in a blast furnace (cast iron is chemically the same as blast-furnace iron) and casting the liquid iron into ingots called pigs. Pig iron is remelted, along with scrap and alloying elements, in cupola furnaces and recast into molds for a variety of products. In the 18th-19th cent., cast iron was a cheaper engineering material than wrought iron (not requiring intensive refining and hammering). It is more brittle and lacks tensile strength. Its compressive (load-bearing) strength made it the first important structural metal. In the 20th cent., steel replaced it as a construction material, but cast iron still has industrial applications in automobile engine blocks, agricultural and machine parts, pipes, hollowware, stoves, and furnaces. Most cast iron is either so-called gray iron or white iron, the colors shown by fracture; gray iron contains more silicon and is less hard and more machinable than white iron. Both are brittle, but malleable cast iron (produced by prolonged heat treating), first made in 18th-cent. France, was developed into an industrial product in the U.S. (see S. Boyden). Cast iron that is ductile as cast was invented in 1948. The latter now constitutes a major family of metals, widely used for gears, dies, automobile crankshafts, and many other machine parts.

Cast iron at English => English (Websters 1913) Of Explained:

Iron \I"ron\ ([imac]"[u^]rn), n. [OE. iren, AS. [=i]ren,
[=i]sen, [=i]sern; akin to D. ijzer, OS. [=i]sarn, OHG.
[=i]sarn, [=i]san, G. eisen, Icel. [=i]sarn, j[=a]rn, Sw. &
Dan. jern, and perh. to E. ice; cf. Ir. iarann, W. haiarn,
Armor. houarn.]
1. (Chem.) The most common and most useful metallic element,
being of almost universal occurrence, usually in the form
of an oxide (as hematite, magnetite, etc.), or a hydrous
oxide (as limonite, turgite, etc.). It is reduced on an
enormous scale in three principal forms; viz., cast iron,
steel, and wrought iron. Iron usually appears dark brown,
from oxidation or impurity, but when pure, or on a fresh
surface, is a gray or white metal. It is easily oxidized
(rusted) by moisture, and is attacked by many corrosive
agents. Symbol Fe (Latin Ferrum). Atomic weight 55.9.
Specific gravity, pure iron, 7.86; cast iron, 7.1. In
magnetic properties, it is superior to all other
substances.

Note: The value of iron is largely due to the facility with
which it can be worked. Thus, when heated it is
malleable and ductile, and can be easily welded and
forged at a high temperature. As cast iron, it is
easily fusible; as steel, is very tough, and (when
tempered) very hard and elastic. Chemically, iron is
grouped with cobalt and nickel. Steel is a variety of
iron containing more carbon than wrought iron, but less
that cast iron. It is made either from wrought iron, by
roasting in a packing of carbon (cementation) or from
cast iron, by burning off the impurities in a Bessemer
converter (then called Bessemer steel), or directly
from the iron ore (as in the Siemens rotatory and
generating furnace).

2. An instrument or utensil made of iron; -- chiefly in
composition; as, a flatiron, a smoothing iron, etc.

My young soldier, put up your iron. --Shak.

3. pl. Fetters; chains; handcuffs; manacles.

Four of the sufferers were left to rot in irons.
--Macaulay.

4. Strength; power; firmness; inflexibility; as, to rule with
a rod of iron.

{Bar iron}. See {Wrought iron} (below).

{Bog iron}, bog ore; limonite. See {Bog ore}, under {Bog}.

{Cast iron} (Metal.), an impure variety of iron, containing
from three to six percent of carbon, part of which is
united with a part of the iron, as a carbide, and the rest
is uncombined, as graphite. It there is little free
carbon, the product is white iron; if much of the carbon
has separated as graphite, it is called gray iron. See
also {Cast iron}, in the Vocabulary.

{Fire irons}. See under {Fire}, n.

{Gray irons}. See under {Fire}, n.

{Gray iron}. See {Cast iron} (above).

{It irons} (Naut.), said of a sailing vessel, when, in
tacking, she comes up head to the wind and will not fill
away on either tack.

{Magnetic iron}. See {Magnetite}.

{Malleable iron} (Metal.), iron sufficiently pure or soft to
be capable of extension under the hammer; also, specif., a
kind of iron produced by removing a portion of the carbon
or other impurities from cast iron, rendering it less
brittle, and to some extent malleable.

{Meteoric iron} (Chem.), iron forming a large, and often the
chief, ingredient of meteorites. It invariably contains a
small amount of nickel and cobalt. Cf. {Meteorite}.

{Pig iron}, the form in which cast iron is made at the blast
furnace, being run into molds, called pigs.

{Reduced iron}. See under {Reduced}.

{Specular iron}. See {Hematite}.

{Too many irons in the fire}, too many objects requiring the
attention at once.

{White iron}. See {Cast iron} (above).

{Wrought iron} (Metal.), the purest form of iron commonly
known in the arts, containing only about half of one per
cent of carbon. It is made either directly from the ore,
as in the Catalan forge or bloomery, or by purifying
(puddling) cast iron in a reverberatory furnace or
refinery. It is tough, malleable, and ductile. When formed
into bars, it is called bar iron.

Cast iron \Cast" i`ron\
Highly carbonized iron, the direct product of the blast
furnace; -- used for making castings, and for conversion into
wrought iron and steel. It can not be welded or forged, is
brittle, and sometimes very hard. Besides carbon, it contains
sulphur, phosphorus, silica, etc.

cast iron at English => English (WordNet) Of Explained:
