With the increase of the proportion of electric furnace steel in the market, the demand for uhp graphite electrode has gradually increased. China’s needle coke resources are further strained, and its prices have been high and highly dependent on imports. This is not conducive to reducing the manufacturing cost of 350mm uhp graphite electrode.
What’s Raw Material used for the UHP Graphite Electorde Production?
In order to reduce production costs, it is urgent to use Chinese needle coke instead of imported needle coke to produce uhp graphite electrodes. Chinese graphite electrode manufacturer, using Chinese domestic needle coke as raw material, adopts new formula and production process technology to carry out the research and development of φ 350mm UHP Graphite Electrode.
Chinese graphite electrode manufacturers, through optimizing the formula and making full use of the established production process and technical conditions, use Chinese domestic needle coke to produce φ350 mm uhp graphite electrode. It can fully meet the requirements of graphite electrode users.
The Advantages of the Chinese Needle Coke Raw Materials
- The Chinese-made needle coke, as the the raw material for the graphite electrodes, which has higher ash content, higher sulfur content, smaller particle strength, and smaller particle tap density.
- The graphite electrode produced from the Chinese needle coke raw material has the following physical and chemical properties: high bulk density, equivalent flexural strength, slightly lower elastic modulus, higher ash content, and higher resistivity.
- Passed the trial of the steel mill, the graphite electrode has good thermal shock resistance and oxidation resistance performance, which can fully meet the customer’s normal use requirements.
- Using uhp graphite electrode produced by Chinese-made needle coke, using large particle formula, the binder adopts medium-temperature modified asphalt or high-temperature modified asphalt, and adopts standard process. The level of the traditional process greatly reduces the production cost and improves the competitiveness of the product, thus achieving the purpose of replacing imported needle coke.
Conclusion
The test of producing φ350 mm uhp graphite electrode by using Chinese-made needle coke was successful. China’s domestic needle-shaped coke raw materials can be popularized for use on medium 400mm and φ450mm uhp graphite electrodes.
It can be seen from the above experiments that using domestic graphite electrode raw materials and through improved production technology, it has been possible to produce 350mm graphite electrode which can meet customer needs.
