Product Description

Product Description

Graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading,molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, with low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance, high mechanical strength, etc.

One-Stop Service to ensure superior quality.
All of our technicians are trained engineers and know all of the EAF, Ladle, and Foundry applications throughout China and Middleast Countries.
We offer an all-round support to the customers for taking our UHP graphite electrodes into operation. Check and analyse the customers' furnace conditions in order to achieve an optimal performance of the graphite electrodes and a decrease of the specific electrode consumption.
We also offer other services including train employees,performance analysis, storage in our warehouses, inspection of accessories, and monitoring the furnace.
