Preparation method of anti-alumina-electrolysis prebaked anode
The invention relates to a preparation method of an anti-alumina-electrolysis prebaked anode, which comprises the following steps: carrying out high-temperature calcination on petroleum coke to obtaincalcined coke, and crushing, screening and grading the calcined coke; adding the obtained calcined coke aggregate and powder into a kneading pot according to a designed proportion, performing kneading and preheating, adding an additive and a binder coal pitch, continuing heating, and uniformly kneading the materials to obtain anode paste; putting the obtained anode paste into a vibration formingmachine for vibration forming; cooling an antioxidant prebaked anode green body, and then placing the antioxidant prebaked anode green body in a roasting furnace for roasting; and after roasting is finished, performing cooling and discharging to obtain an anti-alumina-electrolysis prebaked anode finished product. The preparation method of an anti-alumina-electrolysis prebaked anode has the beneficial effects that the method is used for preparing an anti-alumina-electrolysis prebaked anode, so that the air reaction resistance and the carbon dioxide reaction resistance of the prebaked anode areimproved, the oxidation resistance of the prebaked anode is improved, the carbon residue amount of the anode is reduced, and the service cycle of the anode is prolonged by 1-2 days.
