FAQ
Q: What is the core difference between GPC and ordinary calcined petroleum coke in industrial applications?
A: Ordinary calcined coke is incompletely carbonized, while GPC undergoes full graphitization with intact crystal structure, lower thermal expansion coefficient and superior thermal stability, releasing almost no volatile gas at high temperatures. Beyond basic carbon adjustment, it is more suitable for the production of high-end aluminum electrolysis and refractory materials, with performance standards far exceeding those of conventional casting carburizing raw materials.
Q: Why is graphitized petroleum coke preferentially selected for aluminum electrolysis cathode carbon blocks?
A: GPC has excellent electrical conductivity and strong resistance to high-temperature molten salt corrosion. When used for cathode carbon blocks, it can effectively reduce electrolytic cell voltage and power consumption, while greatly improving structural stability and overall service life of cathode carbon blocks.
Q: What adverse effects will inconsistent or substandard graphitization degree of GPC cause?
A: Insufficient or uneven graphitization leads to increased thermal expansion coefficient and degraded thermal shock resistance of the product. The subsequent carbon products made from it are prone to cracking and spalling under frequent temperature differences, substantially reducing the finished product qualification rate and service life.
Q: Is graphitized petroleum coke applicable to the production of high-temperature carbon refractory materials?
A: Fully applicable. Its dense graphite structure and low gas evolution characteristic prevent pore defects inside refractory bricks and significantly improve the thermal conductivity, high-temperature strength and spalling resistance of carbon-containing refractory products. It serves as a core raw material for high-end refractory materials.
Q: How does GPC help achieve energy conservation and consumption reduction in metallurgical production?
A: The product features low resistivity and stable electrical conductivity, which reduces heat loss and ineffective power consumption in industrial production. Meanwhile, its ultra-high high-temperature thermal stability cuts raw material loss caused by high-temperature oxidation, realizing dual energy savings on electricity and raw materials.
Q: What are the core precautions for bulk GPC warehousing?
A: It must be stored in a dry and ventilated warehouse; long-term moisture exposure is strictly prohibited. Once GPC absorbs moisture, pores will form during high-temperature processing, directly damaging the density and structural strength of subsequent finished carbon products and degrading product performance.
