The continuous casting of the non ferrous alloys is a process that is similar to a liquid state extrusion.

The casting machine can be horizontal or vertical and allows the production of high lengthes bars (standard length about 3 m).

That process allows the manufacturing of the full or cored sections in various shapes : round, square, flat, hexagonal bars and other various shapes.

Principle:

The hot melt which is in a holding furnace goes into a cooled graphite die. The roll-formed bar that is totally solidified is pulled with idle pulleys that are also used as guides. Then it is cut at the requested length.

Advantages:

Thanks to the strong pressure that occurs in the holding furnace due to the cooling speed, the alloy has got a particularly thin, compact, homogeneous, tight structure under high pressure and has no impurities.

That process allows to obtain some semifinished products with a nice appearance, easily machinable, with precise dimensions and high mechanical characteristics.
