centrifugal casting definition

moving away from an axis; the opposite being centripetal force ? The speed of the rotation and metal pouring rate vary with the alloy and size and shape being cast. Processes. There is a difference between vertical centrifugal casting and horizontal centrifugal casting. In centrifugal casting, molten metal is poured into a mold that is revolving about a horizontal or vertical axis. When wound and released, the bar rotates quickly, throwing molten metal outward and into a mold. Centrifugal casting consists of a number of processes in which the centrifugal force set up by the rotation of a part of the casting is utilized to shape the casting, fill the mould and help solidify and strengthen the metal [Pavlovic, et al (2009)]. True Centrifugal Casting The manufacturing process of centrifugal casting is a metal casting technique, that uses the forces generated by centripetal acceleration to distribute the molten material in the mold. definition A means of casting employing the force achieved in a spinning apparatus to push the casting material into a mold. The following operations include in centrifugal casting – rotation of mold at a known speed, pouring the molten metal, proper solidification […] This is a casting technique that has an extensive range of industrial applications including the casting of machine fittings where durability of the finished product is important. Centrifugal casting provides high material soundness and is the metal casting process of choice for jet engine compressor cases, petrochemical furnace tubes, many military and defense components, and other applications requiring high reliability.. • Centrifugal casting remained a casting method for large objects until 1907 when Dr. Taggart, a dentist, introduced it to other dentists who experi‐mented with the method hoping to perfect cast inlays for teeth that would replace malleting (Refers to centrifugal force ? Parts produced by the semi-centrifugal method include gears, fly-wheels and track wheels. True centrifugal casting or commonly known as normal centrifugal casting is used to produce a symmetrical hollow structure with round holes. Vertical centrifugal casting can be used to produce both symmetrical as well as nonsymmetrical parts. Centrifugal Casting A casting process in which centrifugal force is used to force molten metal into a mold. Centrifuged or Pressure Casting: This process is used for non-symmetrical castings having intricate details and also for precision castings. centrifugal casting technique. 1 ) True Centrifugal Casting. The process of using centrifugal force for casting can be divided into three major parts; True centrifugal, semi-centrifugal and centrifuging. Centrifugal casting consists of producing castings by causing molten metal to solidify in rotating moulds. The process has several very specific advantages. The centrifugal force provides high fluid pressure to the force the molten metal into mould cavity. 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. Horizontal centrifugal casting is used to produce rotationally symmetric parts, such as pipes, tubes, bushings, and other parts. moving toward an axis.) Television picture tubes, spherical glass objects, pipes, flywheels, and boilers are also produced by centrifugal casting. iii. [2] An articulated arm is free to spin around a vertical axle, which is driven by an electric motor or a spring. Centrifugal casting has many applications in manufacturing industry today.
