Mechanical strength of electrode paste for submerged arc furnace
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 coarse and fine particles in the electrode paste are prone to stratification, 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 at Rongxin Carbon have read many domestic and foreign materials, but we have not found any materials that specifically discuss the mechanical strength of electrode pastes. In order to promote the improvement of the quality of electrode pastes, and for the manufacturers of electrode pastes to master the performance of electrode pastes, we are Rongxin Carbon. The mechanical strength of electrode paste is specially discussed.
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 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 the 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
