Grade:RP GRAPHITE ELECTRODE GRAPHITE ROD

LARGE SIZE DIA 7000mm-1200mm

Diameter:700-1200MMLength:1600MM-2400MM

Products advantages:

1. Low electric resistivity

2. Good electric and thermal conductivity

3. HighER oxidation resistance

4. Great resistance to thermal and mechanical shock

5. HighER mechanical strength

6. High machining accuracy


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.

production process

Graphite electrodes, mainly petroleum coke, needle coke as a raw material, coal tar pitch as a binding agent, calcined, ingredients, kneading, compression type, firing, graphitization, and machining is made in the form of an arc in an arc furnace release energy for heating the molten charge conductor
