The height of electrode paste refers to the height from the upper end of electrode clip to the top of electrode paste. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to delamination, or the electrode cylinder is swollen due to the pressure of the paste column. If the electrode paste column is too low, it is difficult to obtain a dense electrode because the pressure of the paste column is too small and the filling property is poor. Electrode paste consumption is too fast.
The proper height of electrode paste column is conducive to improving the quality of electrode roasting and reducing consumption. Electrode paste is the conductive electrode of various submerged arc furnaces, and it is an indispensable product in industrial production. Gongyi Sanjing carbon factory has read many domestic and foreign materials, but we have not found the materials that specifically discuss the mechanical strength of electrode paste. In order to improve the quality of electrode paste and master the performance of electrode paste for the manufacturer of electrode paste, Gongyi Sanjing carbon factory specially discusses the mechanical strength of electrode paste.
In the national standard of electrode paste, there is no quality index of mechanical strength of electrode paste, only the quality index of compressive strength of electrode paste. Mechanical strength itself includes compressive strength, and has a certain relevance. As a national standard, it may not be able to put everything into the quality standard. However, the national standard is the standard of more than ten years ago, and the electrode paste industry has developed rapidly in the past ten years, When we Gongyi Sanjing carbon factory specially discussed the strength of electrode paste, we had to make a comparative discussion. The mechanical strength of electrode paste includes compressive strength, flexural strength and tensile strength. The mechanical strength of carbon products is anisotropic, that is, the composition of raw material particles of carbon products is different in horizontal and vertical directions.
Due to the production method of electrode paste, we will not discuss the anisotropy of mechanical strength of electrode paste here. The raw material composition of electrode paste, that is, different raw materials, particle size and proportion of raw materials, thickness and proportion of powder, and the content of coal tar pitch all have an impact on the mechanical strength of electrode paste
