The cause of electrode paste leakage and its preventive treatment 1

 　　The cause of electrodepaste leakage and its preventive treatment

　　Electrode leakage refers to the liquid electrode paste melted in the electrode, which flows out from the damaged electrode cylinder. There are two locations where the leakage occurs: one is below the bottom ring (copper tile), and the other is above the bottom ring (copper tile).

　　(1) Causes of electrode leakage

　　When the consumption speed of the electrode is greater than the sintering speed, the softening section of the electrode is pressed below the conductive element (copper tile). The electrode current exceeds the safe current that the motor barrel can withstand, and the flow paste or soft break will occur.

　　①The quality of electrode paste is not good

　　The volatile content and softening point of the electrode paste are too high, which causes the three-phase electrode to be in a state of underburning, which cannot meet the requirements of the production process, and causes the paste to leak when the electrode is pressed and discharged: the ash content of the electrode paste is too high, which causes the electrode to be consumed quickly. The sintering speed can not meet the consumption speed at all, causing paste leakage.

　　② Unreasonable way of adding up

　　If the paste is not added according to the process requirements, the paste column will be added too high, resulting in slow volatilization of volatiles, and electrode underburn; the paste column is too high, causing the electrode's own weight to exceed the clamping force of the electrode clamping system, causing the electrode to slide down and causing electrode leakage paste.

Study on impurities in high purity flake graphite

Image
 　　For the analysis of trace impurities in high-purity flake graphite, the sample is usually pre ashed or wet digested to remove carbon, the ash is dissolved with acid, and then the impurity content in the solution is determined. The ashing method does not need to use ultra pure acid to dissolve the ash, thus avoiding the risk of introducing the elements to be measured, so it is used more. It is also very difficult to detect the ash content of high-purity flake graphite, because the enriched ash needs to be burned at high temperature, and it is difficult to separate the ash from the sample boat at high temperature, which makes it impossible to accurately determine the composition and content of impurities. 　　The existing methods all take advantage of the characteristic that the platinum crucible does not react with acid, use the platinum crucible to burn the high-purity flake graphite to enrich ash, and then directly heat the sample in the crucible with acid to dissolve th

General technical index requirements for electrode paste

Image
 Electrode occupies an important position in submerged arc furnace. The working conditions of the electrode are bad, the current passing through is high, the temperature difference between the two ends is large, and the production is affected by the impact of mechanical, electrical and charge collapse... Mechanical strength, higher electrical resistivity, better thermal shock resistance, oxidation resistance and smaller thermal expansion coefficient. Generally speaking, the quality of electrode paste is controlled by the following five indicators: 1. Ash: Ash is the residue of electrode paste when it is burnt to constant weight at 850℃-870℃. It belongs to inorganic minerals. It has high ash resistivity, poor strength, high power consumption, and large electrode consumption. In the event of a hard breaking accident, the ash content is a very important indicator, and the lower the better. 2. Volatile matter: Volatile matter refers to the mass loss of electrode paste under the condition o

Performance characteristics of anthracite electrode paste

 Anthracite is the main raw material of electrode paste. The performance of anthracite is related to the performance of electrode paste. Therefore, it is necessary to understand and discuss the performance of anthracite to ensure the quality of electrode paste. Anthracite coal in China is mainly distributed in Shanxi, Ningxia and Guizhou. Shanxi is the origin of anthracite, which is mainly produced in Yangquan and Jincheng. Anthracite is an indispensable raw material for carbon industry. It is mainly used in semi graphite cathode carbon block, electric furnace carbon block, blast furnace carbon block, carbon electrode and various pastes. Studying and discussing various properties of anthracite is very beneficial to improve the quality of carbon products.
