众所周知,石墨化过程是一个自热法加热的过程。它是由炉芯本身的电阻来消耗电能放热,从而使炉芯上升到预定的温度。由于炉芯电阻随着温度的上升而下降到一定值之后保持不变,故炉芯温度也在积累一定的热量从而达到一定值之后就不再上升,这时的外观表征是电流、电压稳定下来。这种相对的稳定状态实际上是一种热动态平衡。 As we all know, the graphitization process is a self-heating process. It is by the furnace itself to dissipate electrical resistance heat, so that the furnace core up to a predetermined temperature. As the furnace core resistance as the temperature dropped to a certain value after the same, so the core temperature is also accumulated a certain amount of heat to reach a certain value after no longer rise, then the appearance of the characterization of the current, the voltage stabilized . This relative steady state is actually a thermo-dynamic balance.
