Performance characteristics of graphite & carbon blocks raw material anthracite
Anthracite is the main raw material of graphite & carbon blocks. The performance of anthracite is related to the performance of graphite & carbon blocks. Therefore, understanding and discussing the performance of anthracite is necessary to ensure the quality of graphite & carbon blocks. my country’s anthracite is mainly distributed in Shanxi, Ningxia and Guizhou. Shanxi is the producing area of anthracite, and Shanxi anthracite is mainly produced in Yangquan City and Jincheng City. Anthracite is an indispensable raw material for the carbon industry. It is mainly used for semi-graphite cathode carbon blocks, electric furnace carbon blocks, blast furnace carbon blocks, carbon electrodes and various pastes. Researching and discussing the various properties of anthracite is very beneficial for improving the quality of carbon products. We have been engaged in carbon work for many years. We have dealt with anthracite in the early 1980s until now. We have visited many places in Yangquan and Jincheng in Shanxi to learn about, inspect, sample, test, compare and analyze, and have accumulated a lot of data on anthracite. The data, and at the same time more than 20 years of use practice, can further research and verify various data of anthracite.
Data based on practical tests are convincing. Anthracite has a low true specific gravity, low ash content, and high sulfur content; Shanxi Jincheng area anthracite has a high true specific gravity, high ash content, and low sulfur content. The difference in the properties of anthracite in different regions should be related to the geological age of the formation of anthracite. Since the raw coal in the Jincheng area is really heavier than the raw coal in the Yangquan area, it can explain why the strength of the anthracite in the Jincheng area is good, and why the anthracite in the Jincheng area has good oxidation resistance. There are some differences in the properties of anthracite after high temperature calcination. The sulfur content of the calcined anthracite in Yangquan area hardly increased, and the specific resistance is 17% lower than that of the calcined anthracite in Jincheng, which may be related to the ash composition of the anthracite. Therefore, in the production process, if you produce graphite & carbon blocks and carbon electrodes, consider first Use calcined anthracite from Yangquan area. Understanding their performance is to improve the quality of the product and make better use. Sometimes you can combine the two to make the performance better.
