During the spun casting process, the liquid steel is poured into a rotating canister and pressed against the outer wall of the canister by the centrifugal forces. After it has been poured in through the centre, the material is rotated at up to x120 acceleration of gravity. Air bubbles and coarse impurities are therefore driven out by the different densities.
After the steel , copper , bronze etc has been poured in, there is a continual solidification from the outer wall of the canister to the inner surface. More delicate ingredients and slag are driven from the front of the solidification to the inside and can then be processed.
This results in a particularly pure, adjusted structure which is comparable with the forged material in terms of its characteristics. Unlike the forged steel, the characteristics are independent of the direction of load – spun casting does not have any lengthways “fibres”.
Spun Casting allows for virtually unlimited range of materials to be used and spun casting offers superior performance at an attractive price.Spun casting combines the high quality and excellent material characteristics of forged steel with the flexibility and productivity of cast parts. If it is suitable in terms of geometry, centrifugal casting is often the first choice in machine and plant construction for stainless steel components that have to withstand pressure.
The use of spun castings are many. Typical applications of centrifugal castings include Decanters , Valves , Pumps , Steel Mill Rollers , Rudder and Propeller Parts in Shipbuilding , Sealing Technology , Industrial Motors.
