Mechanical strength of electrode paste

Pubdate: 01-11 2022

The mechanical strength of the electrode paste includes compressive strength, flexural strength and tensile strength.

The height of the electrode paste refers to the height from the upper end of the electrode clip to the top of the electrode paste. If the electrode paste is too high, the thick and fine particles in the electrode paste are prone to delamination, or the electrode cylinder will be swollen due to too much pressure of the paste column. If the electrode paste column is too low, the pressure of the paste column is too small and the filling is poor, and it is difficult to obtain Dense electrodes. The electrode paste is consumed too quickly. The proper height of the electrode paste column is beneficial to improve the quality of electrode firing and reduce consumption.

Electrode paste is the conductive electrode of various submerged electric furnaces, and it is an indispensable product in industrial production. We have read many domestic and foreign materials, but have not found any materials that specifically discuss the mechanical strength of the electrode paste. In order to promote the improvement of the quality of the electrode paste, and for the manufacturer of the electrode paste to master the performance of the electrode paste, we will specifically discuss the mechanical strength of the 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. The mechanical strength itself includes compressive strength and has certain relevance. As a national standard, it may not be able to All things are put into quality standards, but the national standard is the standard more than ten years ago. The electrode paste industry has developed rapidly over the past ten years. When our factory specifically discusses the strength of electrode paste, we have to do a more comprehensive Explore.

The mechanical strength of the electrode paste includes compressive strength, flexural strength and tensile strength. The mechanical strength of carbon products is anisotropic, that is, the composition of the raw material particles of carbon products is different in the horizontal and vertical directions. Due to the production method of the electrode paste, we will not discuss the anisotropy of the electrode paste’s mechanical strength here. The composition of the raw materials of the electrode paste, that is, different raw materials, the particle size and ratio of the raw materials, the thickness and ratio of the powder, and the content of coal pitch all have an impact on the mechanical strength of the electrode paste. We will discuss it separately. Only the influence of the temperature change of the electrode paste on the mechanical strength during the sintering process is discussed here.
