a. An object at or near finished shape obtained by solidification of a
substance in a mold. ASM, 1
b. Pouring molten metal into a mold to produce an object of desired shape.

c. A process of shaping glass by pouring hot glass into molds or onto
tables or molds. See also:teemer
d. A process for forming ceramic ware by introducing a body slip into a
porous mold that absorbs sufficient water (or other liquid) from the slip
to produce a semirigid article. ASTM
A series of iron molds on an endless-belt conveyor to receive and cast
molten pig iron into form as it comes from a furnace. Mersereau, 2
a. A quarryman's term for an operation consisting of making a cut with a
steam shovel, which, instead of loading the material on cars, moves it to
one side, forming a long ridge.
b. The operation of reestablishing benches that have been covered or
caved, and also cutting up a high bank into one or more smaller banks.
Lewis
The space in a foundry in which molds are placed and castings are made. In
the Bessemer and open-hearth steelworks, it is the space utilized for
casting the molten steel into cast iron ingot molds. Fay
One of several terms (and/or letter symbols) commonly used to designate
low-quality drill diamonds. Long
a. Liquid shrinkage--the reduction in volume of liquid metal as it cools
to the liquidus. ASM, 1
b. Solidification shrinkage--the reduction in volume of metal from the
beginning to ending of solidification. ASM, 1
c. Solid shrinkage--the reduction in volume of metal from the solidus to
room temperature. ASM, 1
d. Total shrinkage--the sum of the shrinkage in definitions a, b, and c
above. ASM, 1
Strain in a casting caused by casting stresses that develop as the casting
cools. ASM, 1
Stress set in a casting because of geometry and casting shrinkage.
ASM, 1
A large turntable with molds mounted on the outer edge. Used primarily in
the base metal industries for cast ingots, anodes, etc.
In ore beneficiation, smelting, and refining, one who operates a large
rotating casting wheel to pour molten, nonferrous metal, such as copper or
lead, into molds mounted on the edge of the wheel. DOT
Iron containing carbon in excess of its solubility in the austenite that
exists in the alloy at the eutectic temperature. For the various
forms--gray cast iron, white cast iron, malleable cast iron, and nodular
cast iron--the word "cast" is often left out, resulting in the terms gray
iron, white iron, malleable iron, and nodular iron, respectively.

An oil. Used in ore flotation as a selective collector and in rustproofing
metal surfaces. Bennett
a. A natural, colorless silicate of lithium and aluminum. Bennett
b. A transparent variety of petalite. Syn:castor
a. A cast unit of explosive commonly used to initiate detonation in a
blasting agent. Dick, 2
b. A cast unit of explosive, usually pentolite or composition B; commonly
used to initiate detonation in a blasting agent.
Steel as cast; i.e., not shaped by mechanical working. Originally applied
to steel made by the crucible process as distinguished from that made by
cementation of wrought iron. CTD
A prefix to indicate that the rock belongs to the deepest zone of
metamorphism, which is characterized by very high temperature, hydrostatic
pressure, and relatively low shearing stress. CF:epi-; meta-; meso-.
Syn:kata-
Rock deformation accomplished by fracture and rotation of mineral grains
or aggregates without chemical reconstitution. AGI
A cataclastic rock that has been formed by shattering (or cataclasis),
which has been less extreme than in mylonite. See also:augen gneiss;
crush breccia; mylonite; mylonite gneiss.
a. Pertaining to the structure produced in a rock by the action of severe
mechanical stress during dynamic metamorphism; characteristic features
include the bending, breaking, and granulation of the minerals. Also said
of the rocks exhibiting such structures. See also:mortar structure
AGI
b. Pertaining to clastic rocks, the fragments of which have been produced
by the fracture of preexisting rocks by Earth stresses; e.g., crush
breccia. Syn:kataclastic
