| Graphite
Side 
The ordinary
and the high strency & density Graphite Sides are selected
from the refinery coke ,adopting the advanced production craft
and the equipment .The products have the properties of the
high strengt 、 compression 、 bending strength 、 low rate of
porosity 、 excellent anticorrosion11 、 anti-alkalescence and
so on ,which have becomed the best raw materials for the metalluriall
furnace 、 the resistance furnace 、 the furnace lininng ablation
、 the chemical equipment 、 the mechanical mold 、 and the heterogeneous
type graphite processing .

Graphite
Electrode 
The Grahite Electrodes
of our company are mainly the NP electrode and the HP eletrode
.After the impregnation of bitumen,all the Specifictions
of the graphite side`s physics and chemical surpass the
national standards.They have becomed the best choice of
the industry Silicon ,Phosphor and Emery smelting .
