Graphite electrode

At present, the company's products mainly have four series:

First, various specifications of ordinary power, high power, quasi-ultra-high power, ultra-high power graphite electrode and oxidation resistant impregnated graphite electrode for smelting;

Second, crude graphite in new carbon materials with excellent chemical corrosion resistance, excellent oxidation resistance and high temperature stability;

Third, various specifications of isotropic high-density, high-strength, high-purity graphite;

Fourth, all kinds of non-standard graphite products for graphite chemical equipment and machinery manufacturing, all kinds of special-shaped carbon products and graphite processing products.
