In the realm of alloy smelting, the volatile content within electrode paste stands as a critical determinant of process efficiency and product quality. Controlling this volatile component within precise parameters is imperative, as deviations can lead to a cascade of adverse effects. Understanding the nuanced impact of volatile content on sintering, strength, and consumption rates is indispensable for optimizing industrial smelting operations.
The volatile content of the electrode paste must be controlled within the corresponding area, otherwise the following results will occur.
If the volatile content is too high, it will easily cause the following adverse effects:
(1) It is not easy to sinter, has poor strength, and is easily broken.
(2) It has high elasticity, poor compressive strength, and may be hard broken.
(3) Oxidation occurs quickly and electrode paste is consumed quickly.
(4) It is very easy to sinter into special shapes in layers. In addition to being difficult to lower the electrode, it is also easy to break.
If the volatile content is too low, the following adverse consequences will occur:
(1) Premature sintering, poor strength, and easy to break.
(2) The adhesion is not enough, the strength is poor, and it is easy to break.
(3) The contact resistance between the electrode and the conductive jaw plate is large, which affects the power consumption and the life of the jaw plate.
If we compare the above situations, the consequences of too high volatile content are worse than too low. Therefore, the volatile content of the counter electrode paste must be controlled within a certain range.
The lower the ash content requirement in the electrode paste, the better. However, due to the source of raw materials, it is generally not higher than 5%. If the ash content is too high, the strength will become poor, the resistance will be high, the power consumption will be high, and the corresponding electrode consumption will be high.
