For electrode paste products, if the amount of coal asphalt binder is not appropriate, "hard break" or "soft break" accidents will occur in the process of self-curing.
If the amount of coal asphalt is too much, the sintering speed of carbon paste during self-calcining will be slower than the consumption rate, resulting in soft fracture accident. Moreover, the amount of coal asphalt is too much.
The porosity and strength of the sintered carbon electrode will be large and low, and hard fracture will occur under certain conditions. For example, if the amount of coal asphalt is too little, the electrode paste and sintering will be too fast.
The poor binding force and low strength between the carbon electrode aggregate particles also lead to hard fracture, which affects the normal operation of the furnace.
It can be seen that the soft break or hard break of electrode paste is related to the coal pitch content of electrode paste.
