It is acknowledged that both Horizontal and Vertical Centrifugal Casting processes can be used with ferrous and non ferrous materials. The same machines can cast ferrous and non-ferrous, the only difference is some process features have to be tailored to suit the alloy such as:
- Spinning speeds
- Pouring rates
- Mould temperatures
- Molten metal temperatures
- Mould Coating
- Water Cooling
Horizontal Centrifugal Casting is best applied to castings of greater length than the diameter and which have cylindrical bore. This is why you will commonly find tubes between 300mm to 6000mm long. It is possible to create shaped casting horizontally using a shaped mould or sand inserts.
Vertical Centrifugal Casting on the other hand is commonly used for cylindrical shapes where the diameter exceeds the length or height of the casting one exception to this are steel mill rolls where using a roller guide system, casting with a longer length to the diameter are manufactured this is to allow the manufacture of solid castings.
It can also be used for complex castings shapes such as Ball Valves and Propellers.
Due to the gravitational pull while pouring the material a parabolic effect takes place in the bore, this can be altered by changing the speed for casting.
