Lining process for cold ramming paste of submerged arc furnace 2

 　　At present, there are many companies preparing cold ramming paste for furnace building, mainly using calcined anthracite, graphite, etc. as aggregates, modified asphalt as binder, coal tar, resin, etc. as additives, and various anti-shrinkage materials. It is kneaded with the main raw materials. It is not only used for the overall construction of submerged arc furnaces, but also for partial repair of the furnace lining. However, due to process reasons, there is still layer-to-layer delamination, causing major accidents.

　　At present, through the efforts of many carbon material companies, the technology and process of cold ramming and pasting furnace construction have reached the higher requirements that can meet the construction of any kind of submerged arc furnace. Among them, Guizhou Congrey Carbon Material Co., Ltd. and its subsidiary Guizhou Ali Submerged Arc Furnace Technology Development Co., Ltd. and its R&D center conduct research and adjustments on the formulation of cold mash materials for different furnace types, different construction conditions and production requirements. 

For some special cases such as rare earth smelting electric furnaces, specific technical requirements are adopted and formulated to adjust the process parameters. Use cold ramming to reduce the inner diameter of the phosphorous furnace, change the unreasonable furnace production process coefficient, and increase the yellow phosphorus output accordingly. For example, the 3.2MVA phosphorous furnace of the Sanjiang Yellow Phosphorus Plant in Guiyang, about 4.5t before the renovation; 5t after the technical renovation many. The six 15MVA phosphorous furnaces of Qianneng Company were successfully modified by cold pounding process, which increased the output of each furnace from 17-18t to 21.5-22t. The electric power consumption of its electric furnace was 14500kWh/t before the technical reform, and after the technical reform, the power consumption was about 13,800kWh/t. Effectively realize the effect of increasing production and energy saving, and prolong the service life of the furnace body.

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.
