3. What is UHP Graphite Electrodes?

Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. 

In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power.

5. Our UHP Graphite Electrode Advantages

• High Graphite Electrode Density, High Temperature Strength

• Low Thermal Expansion

• Excellent Thermal and Electrical Conductivity

• Good Machinability

6. Our UHP 500mm Graphite Electrode Application

Graphite electrodes are used for the recycling of steel in the electric arc furnace industry, so called "mini-mills". 

In the steelmaking process, iron scrap gets melted in an electric arc furnace and recycled. Graphite electrodes, a kind of conductor, are an essential component in this kind of furnace.They can melt scrap at a temperature of about 1600℃.

 

7. UHP Graphite Electrode Manufacturing Process

Needle coke has the features of needle-like crystals develop and low thermal expansion coefficient.
Pitch is produced by heat treatment of coal tar carbonizes under heat (50% yield).
Needle coke and pitch are mixed and then molded. Heat treatment is then applied in the baking and graphitization process to form the finished product.

8. Quality Assurance of Our UHP Graphite Electrode

RP HP UHP Graphite electrode by Rongxin Carbon is made to last, thus make Rongxin carbon as a reputed and trusted name on market. We've provided the best value for quality, price, and service to our customers for more than 20 years. Our business success rooted in "No compromise on quality", third party inspection such as SGS is available before delivery.
