There are different types of CCM machines used in the factories currently, depending on the application and requirements of the steel production. Some of the common types are:

Vertical bending CCM: This type of CCM has a vertical section where the molten metal is poured into the mold, and then a curved section where the strand is bent horizontally. The bending radius can be adjusted to control the solidification rate and quality of the strand. This type of CCM is suitable for producing billets, blooms, and slabs with high productivity and flexibility.

Horizontal CCM: This type of CCM has a horizontal section where the molten metal is poured into the mold, and then a straight section where the strand is cooled and cut. This type of CCM eliminates the bending and straightening stresses on the strand, which improves the surface quality and internal integrity of the product. This type of CCM is suitable for producing thin slabs, strips, and wires with high speed and efficiency.

Curved CCM: This type of CCM has a curved section where the molten metal is poured into the mold, and then a straight section where the strand is cooled and cut. The curvature of the mold can be varied to optimize the solidification conditions and product quality. This type of CCM is suitable for producing round and square billets with high metallurgical quality and low energy consumption.
These are some of the main types of CCM machines used in the factories currently, but there may be other variations or combinations depending on the specific needs and preferences of the steel producers
