Production process of graphitized petroleum coke

The production process of graphitized petroleum coke involves several steps. Here's a general overview of the process:

Petroleum Coke Production: Petroleum coke is a byproduct of the refining process in oil refineries. It is produced from heavy petroleum residues by coking or cracking processes. Initially, crude oil is processed in a refinery to extract various products like gasoline, diesel, and jet fuel. The residual oil left after the extraction is subjected to high-temperature coking or cracking, resulting in the formation of petroleum coke.

Calcination: The raw petroleum coke obtained from the refining process contains impurities and volatile components. To remove these impurities and reduce the volatile content, the petroleum coke is subjected to a process called calcination. Calcination involves heating the coke at high temperatures (typically between 1200 to 1400 degrees Celsius) in a controlled environment, such as a rotary kiln or vertical shaft kiln. This process helps to improve the physical and chemical properties of the coke.

Crushing and Sizing: After calcination, the calcined coke is crushed into smaller particles. The coke is typically crushed to a specific size range to meet the requirements of different applications. Crushing is usually done using crushers or mills.

Blending (Optional): Depending on the desired specifications, different batches of calcined coke may be blended together to achieve the desired carbon content and other properties. Blending allows for customization and optimization of the final product.

Graphitization: The crushed and optionally blended coke is then subjected to a graphitization process. Graphitization involves heating the coke to even higher temperatures (usually above 2500 degrees Celsius) in a controlled environment, such as a graphite furnace. This high-temperature treatment transforms the amorphous carbon structure of the coke into a more ordered and crystalline graphite structure. The process helps to increase the carbon content and improve the electrical conductivity and thermal properties of the coke.

Cooling and Packaging: Once the graphitization process is complete, the graphitized petroleum coke is cooled down. It is then packaged in different forms, such as bulk bags, big bags, or smaller bags, depending on the requirements of customers and the intended use of the coke.

It's important to note that the specific details of the production process may vary depending on the manufacturer and the equipment used. Additionally, various quality control measures are implemented throughout the production process to ensure the final product meets the desired specifications and standards.

Why REDSUN 

As far as we know the main reason for any valuable customer from different part of the world is looking for some best-cheapest products from the manufacturing center---China.

Those who only care about price but ignore even the very basic reasonable quality may not have the interest in REDSUN, because we insist to do business in a honestreliable and reasonable way.

It means that we should never be able to be win the simple price competition with those so-called flexible yet unregulated factories or traders, but we believe there are also enough reasons for you to consider cooperating with us, because we can offer you the following keypoints, which are very critical for international business.

1 Deal with big company

We have a close relationship with the top brands, continuous investment in both facilities and R&D support us to be strong and powerful in the market with best quality price combination.

2 Deal with good company

To be big is not everything, to be famous is also not the whole story, only to be really good can support your long term business in a foreign country, which you mostly rely on the phone or computer to communicate with.

Have you ever been:

1 It is always a nice experience for you to communicate with the seller before the down payment is arranged, but possibly you will run into atough or even difficult situation when receive the goods at your port if you choose the wrong one.

Then you may decide never come to China again!

2 You maybe led to another small factory by the sales and offer youcheaper price but you need to pay money to a unknown company which could run away on the next morning.

3 You may be frustrated to be informed that due to the cost increased, the order you already confirmed and pay deposit need tochange price, or delay too much for loading.

4 You may be surprise that nobody inform you there will be the biggest holiday in China and you are dying for the goods to come, which cause you a big lost due to the delay. What REDSUN do is that whatever customer you are, big or small as long as we reach a deal and start the business, we will keep words confirmed during the negotiation. It means we will keep a very close eye on the process to avoid any mistakes.

Our QC team will carry on the agreed standard strictly to inspect the products before they deliver to the next step. What you get will be 100% the same as what you have seen and confirmed.

Only if you strongly request to lower the quality standard but we always have our own bottom line instead of agreeing any price but steal the material in the end.

We will be honest enough in case any problem occur during production and communicate with you to figure out the solution together. We must confess there could always be questions or problems, but when we decide to work together we are in the same boat so good business is always the result of good communication and mutual understanding.

In REDSUN, all the representatives are good English speaker with humble attitude to listen to customer's request. 

Quick response to customer's request for samples, drawings quotations, and answers about any technical problems We admit there must be something we could not do the way is to communicate openly. 

Our people would always let customer know what we could do and what could not, we do every best to realize our company's commitment to you that: what you see and hear is what you get.
