The graphite mold is typically water cooled. This allows the molten metal to solidify within the die, the custom solid metal form is then extracted from the mold and pulled/passed through rollers and water sprays. This process removes the heat from the metal, and gradually solidifies it. Graphite is a widely used material in continuous casting.
Graphite (/ ˈ ɡ r æ f ˌ aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

Pyrolytic graphite is a form of graphite produced by high temperature decomposition of hydrocarbon gases in vacuum followed by deposition of the carbon atoms to the substrate surface. The process is called Chemical Vapor Deposition (CVD).
Graphite Lubricant Batch Process This example illustrates the ingredients, routing instructions in operation number sequence, and the co-products and by-products that the graphite lubricant batch process produces:
Graphite can be mined or synthetically produced from petroleum byproducts from the oil refining process. Mined or natural graphite is known as plumbago, black lead, and mineral carbon and is found in layers in a lamellar shape with a grey to black luster, a greasy feel, and in flaky, crystalline, and amorphous forms.
Graphitization is a post-process that transforms carbon graphite into graphite. It is often used to improve the material's oxidation resistance and self-lubricating ability. During this process, carbon graphite is heated to approximately 5,000°F in a controlled atmosphere for over a week.
This process is called pyrolysis. The resulting binder coke ensures the integrity of the molded and baked blocks. After baking, the blanks do not yet possess a complete graphitic structure. They are brittle and, generally, exhibit high mechanical strength and hardness. At this stage, the material is called carbon/graphite or "hard carbon".

Spherical graphite grinding system: The spheroidization process is the most important step for making cathode & anode materials. Prominer has the ability to provide the complete spherical graphite grinding system including primary crushing mill, shaping mill, air classifier and dedusting system.
Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.
