Metal Mineral

In recent years, the pace of development of the foundry industry is very fast, especially with the development of the market, low-cost market has become an indispensable element, therefore, carbon additive during casting use, can significantly increase the amount of scrap, reducing the amount of pig iron with or without iron. This allows more reduce production costs. This foundry industry is undoubtedly a good news. today I talk abou他for everyone : cast iron carbon additive .
Cast Carburant as a material fact, there are many details you can see the & quot;Classification of carbon additive& quot;, commonly used synthetic graphite, calcined petroleum coke, natural graphite, coke, anthracite and the use of such material dubbed mix. Various carbon agent, the best quality is also known as artificial graphite graphitized petroleum coke.
Many people may not know is how processed into artificial graphite graphitized petroleum coke by carbon agent. Let me tell you about the process.

Cast iron carburant - also known as artificial graphite graphitized petroleum coke

The main raw material for producing artificial graphite powder is high quality calcined petroleum coke, asphalt as a binder in which you add, then add small amounts of other materials. With a good variety of raw materials after the 2500 ~ 3000 ℃, non-oxidizing atmosphere in the process, so that graphitization, called graphitized petroleum coke. After high temperature treatment, ash, sulfur, gas concentrations are significantly reduced, so it is a high quality carbon additive.

Cast iron carburant - outstanding advantages
Compared with traditional cast iron:
1) This product is no residue, high utilization
2) ease of production, saving production costs
3) the content of phosphorus and sulfur content is much lower than in pig iron, stable performance
4) the use of graphitized carbon agent can greatly reduce the production cost of castings
5) and distributing it evenly refine the graphite in the matrix
