Precautions when using graphite electrodes

1.When loading materials into the furnace, in order to reduce the impact on the electrodes from material collapse, large chunks of material should be placed near the bottom of the furnace. Also, avoid the accumulation of non-conductive objects such as lime directly below the electrodes, as it may affect electrical conductivity or cause electrode breakage.

2.Pay attention to the position of the furnace cover. If the cover is misaligned, the electrodes may rub against the cover and get damaged or even break when moving up or down.

3.A set of connected electrodes should not be placed horizontally to prevent breakage.

4.When connecting electrodes, if any joint bolts are found to be loose, they should be tightened before use.

5.If gaps are found after connecting the electrodes, the cause must be identified and the gaps eliminated before use.

6.The electrodes should be used vertically to avoid tilting during operation.

7.Correct connection positions for electrodes and joints (refer to Figure 1).

8.Position requirements for electrode holders (refer to Figure 2), which should be placed outside the caution line of the top electrode.
Note: The holder should not be placed inside the caution line or on the middle electrode, as this may cause electrode breakage.

9.Due to differences in materials and manufacturing processes among manufacturers, there are differences in the physical and chemical properties of electrodes and joints. Therefore, it is generally not recommended to interchange electrodes and joints from different manufacturers.

10.For furnaces with significant vibrations, using pins can help prevent loosening or disconnection.
