100% casting yield.
The process can be easily mechanized and thus unit labor cost is less.
Casting surfaces are better.
Grain size and structure of the casting can be easily controlled.
Applications of Continuous Casting

It is used for casting materials such as brass, bronzes, zinc, copper, aluminium and
its alloys, magnesium, carbon and alloys etc.
Production of blooms, billets, slabs, sheets, copper bar etc.

It can produce any shape of uniform cross-section such as round, rectangular, square,
hexagonal, fluted or gear toothed etc.
