In centrifugal casting, a permanent mold is rotated continuously at high speeds (300 to 3000 rpm) as the molten metal is poured. The molten metal spreads along the inside mold wall, where it solidifies after cooling. The casting is usually a fine-grained casting with an especially fine-grained outer diameter, due to the rapid cooling at the ...
Semi- and true-centrifugal processing permit 30–50 pieces/hr-mold to be produced, with a practical limit for batch processing of approximately 9000 kg total mass with a typical per-item limit of 2.3–4.5 kg. Industrially, the centrifugal casting [8] of railway wheels was an early application of the method developed by the German industrial ...
Centrifugal casting is a metallurgical manufacturing process by casting that may refer to either: Centrifugal casting (industrial), on an industrial scale;
Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1] Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, turbocharger turbines and engine cylinder blocks.

In cast iron pipe, the graphite forms flakes during the casting process, when examined under a microscope. Cast iron pipe was superseded by ductile iron pipe , which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s.
The first use of digital computers to solve problems related to casting was carried out by Dr K. Fursund in 1962, who considered the penetration of steel into a sand mold. [6] A pioneering work by J. G. Hentzel and J. Keverian in 1965 was the two-dimensional simulation of the crystallization of steel castings, using a program developed by ...
Centrifugal casting, or centrifuging, [1] is used as a means of casting small, detailed parts or jewelry. [2] An articulated arm is free to spin around a vertical axle, which is driven by an electric motor or a spring. The entire mechanism is enclosed in a tub or drum to contain hot metal should the mold break or an excess of metal be used.
Centrifugal (a key concept in rotating systems) may refer to: Centrifugal casting (industrial) , Centrifugal casting (silversmithing) , and Spin casting (centrifugal rubber mold casting), forms of centrifigual casting
