Centrifugal Casting Keeps It Cool
Sometimes a business needs to create a large amount of stock that will be used for other purposes later. Some companies might have a large surplus of rough steel tubing kept in stock because they plan to use that tubing down the line for a variety of different applications. The tubing may eventually be refined for sale to the public, or the tubing may be melted and used in other projects. A popular method certain industries employ to create a lot of stock is called centrifugal casting. This process is used most often in the industrial sector to machine large number of cylinders that are intended for a variety of functions.
Centrifugal casting, when used in the industrial arena, is meant to create a large amount of a product that is meant to remain as rough material. So any cylinder made by way of the centrifugal casting process is kept unrefined. If the cylinder is to be employed in some venue where it is meant to be in a different state, it can be further machined or shaped for that use.
Centrifugal casting works by spinning the contents of the cast’s mold at a high rate of speed. Much like the Gravitron of carnival fame from your childhood, the spinning forces the molten metal to the outside walls of the mold, creating the shape of the cylinder. Because the outside of the cast is cooler than the inside, whatever is pushed against the inner walls of the mold cools enough for the cylinder to take and hold its shape. Centrifugal casting is a pretty fascinating process, but one of the neatest features of centrifugal casting is that if there is anything in the metal that should not be there, the pressure placed on the metal from the spinning will force those alien elements from the metal so that they can be removed easily.
