Inspection of graphite heater

　　The graphite heater shall be inspected and managed in the early stage before use, otherwise, the graphite heater may explode during use.

　　The following should be done:

　　1. First of all, check whether the graphite heater has cracks in the early stage of work. If there are no cracks, put the graphite heater above liubaidu and dry it sufficiently;

　　2. There shall be no ponding around the furnace and in the pit in front of the furnace, and there shall not be too many irrelevant objects piled near the graphite heater;

　　3. Strictly check whether there are explosives in the charge, preheat and keep dry when adding charge, and add graphite heater slowly.

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.
