铝用炭素主要分为炭素阴极和炭素阳极两大类。铝电解槽阳极有阳极糊和预焙阳极之分,前者用于自焙阳极电解槽,后者用于预焙阳极电解槽。阴极炭块又分为无烟煤炭块、半石墨质炭块、石墨质炭块和石墨化炭块。 Aluminum carbon is divided into carbon cathode and carbon anode two categories. The anode of the aluminum cell has an anode paste and a prebake anode. The former is used to self-roast the anode cell and the latter is used to prebake the anode cell. Cathode carbon block is divided into anthracite coal blocks, semi-graphitic carbon blocks, graphite carbon blocks and graphitized carbon block.
