Main material is calcined coke and coal tar pitch as binders , via burdening, mixing, extruding, baking, (dipping),
graphitizing, and machining to form. This product have the advantage of low specific resistance, high electric and
thermal conductivity, excellent resistance to oxidation, high thermal shock resistance and mechanical strength, can
be machined easier. Our graphite electrode products including RP, HP, and UHP. Widely apply into EAC smelting for
alloy steel and other metallic or nonmetallic materials. We can also painting the electrode with wax, oil etc.as your required.
Character
The figures are based on room temperature, except where otherwise stated. The average values vary according to
the electrode diameter.
High Degree Purity
The high purity of our graphite electrodes is sufficient to meet the most exacting demands of customers.
Resistance to Thermal Shock
In addition to mechanical stress, graphite electrodes also have to withstand high
thermal shock. Careful selection of raw materials, their mixing and processing have
contributed to a substantial increase in thermal shock resistance, thus greatly improving
the stability of the electrodes and eliminating to a great extent the tendency of cracking
under high load due to insufficient temperature compensation under the varying
operational conditions. The desired shock resistance is attained by favourably balancing
the decisive material characteristics such as thermal expansion, thermal conductivity,
strength and elasticity.
Mechanical Strength
With the exception of extreme cases, the graphite electrodes are capable of withstanding
to high mechanical stress during the electric arc furnace operation. Mechanical strength
attains its maximum when, at higher temperatures, the greatest mechanical stress occurs.
Mechanical strength is also of particular importance in connection with the reduction of the
tips of the electrodes caused by lateral oxidation.
Electrical Resistance
Low electrical resistance is an important feature of graphite electrodes. Actually this characteristic
is essential for coping with the high current densities which electrodes and nipples are subject to in the electric arc furnaces
