Continuous Casting using Graphite Moulds

Continuous casting is a high volume method used to create long continuous metals from an open ended mould (die).

The molten metal is poured in and the water cooled graphite solidifies the metal as it passes through the die. The custom metal created is then extracted and usually cooled further with water sprays and rollers; gradually solidifying the billet, bloom or slab created.

Here is a short video on the continuous casting process used in the manufacturing of steel. In the video copper moulds are used but if you read below you will see why graphite is a better option for continuous casting:

Reasons to use graphite for continuous moulds:

  1. Graphite is a self-lubricating "solid lubricant" which creates low friction between the mould surface and the solidifying metal; ensuring smooth extraction of the casting without cracks.
  2. Graphite is easily machined and complicated shapes can be created for the perfect mould.
  3. The high thermal conductivity of graphite makes for increased extraction speed of castings (with a faster heating-cooling cycle).
  4. Graphite has a high mechanical strength that increases with temperature.
  5. Graphite has a high thermal shock resistance which allows it to withstand sharp changes in temperature; reducing the likelihood of cracking and deforming.

For a fine detailed intricate mould for high volume runs we would recommend our High-quality Isostatic Graphite as the high density and small particle size makes for a long lasting mould with increased strength and a perfect finish.
