The main problems and solutions of electrode paste manufacturers

Pubdate: 12-24 2021

The main problem that plagues electrode paste manufacturers is that the electrode paste baking speed is too slow.

Some manufacturers adopt methods to reduce the amount of asphalt used. This method is effective to a certain extent, but too low amount of pitch causes the fluidity of the electrode paste to deteriorate, and the electrode paste is not easy to be filled in the electrode cylinder, and the density after sintering is poor and it is easy to cause hard fracture.

Another method is to lower the softening point of the pitch and increase the sintering speed of the electrode. However, the softening point of the pitch cannot be reduced indefinitely, because the pitch with a too low softening point reduces the coking rate of the pitch, and the strength of the electrode should also be reduced. There is a hard break phenomenon.

Therefore, in addition to properly mastering the above two methods in the production of electrode paste, the sintering speed of the electrode must be improved through the adjustment of the formula. The conduction heat obtained in the furnace can speed up the firing speed. At the same time, trying to reduce the consumption of the electrode to reduce the speed of the electrode lowering can also achieve the matching of the electrode consumption and the firing.
