Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode processing, in particular to an impregnation device for graphite electrode processing. Background Art

[0002] The porosity of the raw graphite electrode after pressing is very low. However, after the product is roasted, part of the coal tar pitch decomposes into gas and escapes during the roasting process, while the other part cokes into asphalt coke. The volume of the generated asphalt coke is much smaller than the original volume of the coal tar pitch. Although it shrinks slightly during the roasting process, many irregular tiny pores with different pore sizes are still formed inside the product. The presence of a large number of pores will inevitably have a certain impact on the physical and chemical properties of the product. Impregnation is a process that reduces the porosity of the product, increases the density, increases the compressive strength, reduces the resistivity of the finished product, and changes the physical and chemical properties of the product.

[0003] Existing graphite electrodes are all immersed in the impregnation liquid for a circle, and then taken out, and they cannot be in good contact with the impregnation liquid, such as the impregnation device for graphite electrode production disclosed in the patent with authorization announcement number CN 211141538 U, which leads to poor impregnation effect.
