Talking about the choice of electrode paste for anthracite
Anthracite is the main raw material of electrode paste. The performance of anthracite is related to the performance of electrode paste.
Anthracite is the main Raw material of electrode paste. The performance of anthracite is related to the performance of electrode paste. Therefore, understanding and discussing the performance of anthracite is necessary to ensure the quality of electrode paste.
China's anthracite coal is mainly distributed in Shanxi, Ningxia and Guizhou. Anthracite in Dawukou, Ningxia is the best quality anthracite. Anthracite is an indispensable Raw material for the 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 the various properties of anthracite is beneficial to improving the quality of carbon products.
We have been engaged in carbon work for many years. We have been dealing with anthracite since the early 1980s. We have visited Ningxia Coal Mine many times to understand, inspect, sample and test, compare and analyze, and accumulated a lot of data on anthracite, and there are more than 20 Years of use practices can further study and verify various data of anthracite. The data on the practice test is convincing.
Anthracite has a low specific gravity, low ash content and high sulfur content; the anthracite coal in Shanxi Jincheng area has a high specific gravity, high ash content and low sulfur content. The difference in the performance of anthracite in different regions should be related to the geological age of anthracite formation. Since the true proportion of raw coal in Ningxia is larger than that in Yangquan, it can explain why the strength of anthracite in Ningxia is good, and why the anthracite in Ningxia has good oxidation resistance. There are some differences in the performance of anthracite after high temperature calcination. The sulfur content of calcined anthracite in Ningxia has hardly increased, and the specific resistance is 17% lower than that of Jincheng calcined anthracite, which may be related to the ash composition of anthracite. Therefore, in the production process, if the production of electrode paste and carbon electrode is first considered to use Dawu Calcined anthracite in the mouth area.
