Preparation of electrode paste before filling

 Before filling, the electrode paste shall be broken into 80 ~ 100mm small pieces, so that the electrode paste can pass between the two ribs smoothly. If the particle size is too large, the electrode paste suspension fault is easy to occur; If the particle size is too small, it is easy to cause paste spraying. It is better to buy the finished electrode paste. If the material supplied by the manufacturer is qualified, it can be directly filled. The powder of broken electrode paste is reduced, the utilization rate of electrode paste is improved, and the cost of calcium carbide is reduced. Use a forklift to transport the electrode paste to the carbide furnace with a trolley or special tools, and use an electric hoist to lift the electrode paste into the electrode barrel. Pay attention to lifting * during filling.

　　When installing the electrode paste, pay attention not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid the electric ignition accident. Every time the electrode paste is filled, the site shall be cleaned, especially the electrode paste scattered on the equipment.

　　When adding electrode paste, it is necessary to pay attention that people do not touch the two-phase electrodes at the same time to prevent electric shock. It is also important to note that the two-phase electrodes should not be removed at the same time for conductive objects to prevent power connection.

　　In addition, most of the electrode pastes in China are square three pieces. It needs to be broken in use. At present, some manufacturers have improved the shape of electrode paste and made it into ellipsoid with appropriate particle size. For example, the sealed electrode paste produced by Fuzhen carbon is 72mm * 65mm * 120mm, with a mass of about 500g. It has the following advantages:

　　(1) Convenient loading, unloading, storage and transportation;

　　(2) The finished products are screened and the slag is removed in the loading and other processes for many times without weight loss;

　　(3) Less dust pollution, *, reliable;

　　(4) The particle size is moderate, and no electrode paste spraying accident will occur.

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.
