Graphite Electrode
Graphite Electrode takes the high quality petroleum coke, needle coke, coal tar as raw material after the process of kneading, molding, baking and pressing. And then it was treated with impregnation and subsequent graphitized at 2500ºC, was produced by mechanical processing again.
The diamter of our RP HP SHP and UHP graphite electrode is 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm with length 1500mm, 1800mm, 2400mm and 2700mm.

leader in Electrode Technology Upgrade and Process Innovation
Founded in 1992, Rongxing Group is committed to electrode calcination and electrode development and manufacturing. In the development process, the company introduced world's advanced electrode production technology and manufacturing equipment, which greatly improved the output and quality of the product. Automated production of electrode can ensure stability and good quality, while also ensuring the confidence of users. So far, our electrode factory possess a complete set of automation equipment, including one computer control center, one automatic batching system, eight eight-ton kneading pots, eight water-cooled production lines, and so on. Our electrode, graphite electrodes and other products are exported to Russia, Bangladesh, Mongolia, Egypt, Italy, South Africa, France and other countries and regions, which enjoys good reputation.
Rongxing Group Exports Electrode to Many Countries
Since the technical transformation in 2008, it has been eight consecutive years we have not received any complaints from customers for the quality issues. Our electrode product has been entitled with first-class level domestically in product quality and unit consumption control. In the past 24 years, Rongxing electrode has served more than 300 customers. We often play the role of firefighters to help new customers deal with electrode accidents such as soft, short and hard breakage. Those customers have already become our trusted partners. While meeting domestic demand, our electrode, graphite electrode, graphite scrap, graphite powder have been exported to Indonesia, South Africa, India and other countries through various channels, which were recognized by international customers. As an outstanding leader of China's electrode supplier, Rongxing Group was invited to participate in the Canton Fair and international exhibition shows to exhibit the electrode products and received good reputation.
These companies use electrode produced by us.Why choosing us?
- 128 years of expertise in R&D and production of electrode, with a good reputation;
- 2Serving more than 300 domestic alloy factories, and enjoys popularity among large overseas alloy factories;
- 3Fully automated electrode production line, with more precise formulation control and stricter quality control;
- 4Annual output of 200,000 tons to meet the large demand of major customers;
- 5lower unit consumption.
Lower unit consumption, strict quality control
Advantages of Product
The biggest difference of Rongxing electrode is very unique. The main ingredient of our electrode is made of high-quality Ningxia "Taixi Coal" (others may use Ningxia general anthracite, and some use general calcined anthracite) The raw materials Includes graphite scraps with a carbon content of up to 99.9% (others may not use such high-cost raw materials). The production line is a fully automated production line, from the crushing of ingredients to the final kneading molding, most of them are controlled by a computer. The electrode is more in line with the needs of submerged arc furnaces to ensure a long-term and stable supply of electrode.
Quality is being guaranteed
If you compare our electrodes in price alone, our advantages and value cannot be fully reflected. We all know that the importance of electrode to the alloy submerged arc furnace is not only reflected in the price concessions. You choose our products for long-term stable use. Our products are cost-effective.
