Pre-Baked Carbon Anode plays a very important role in the process of aluminum electrolyzer and is known as the "heart" of electrolyzer.It is one of the basic raw materials of aluminum electrolysis industry, which leads the direct current into the electrolytic cell as a conductor and participates in the anode reaction process as the anode material of the electrolytic cell.Renewable resources carbon anode carbon block power supply solution of factory production use, restricted by electrolytic cell in use process, the anode carbon block at the top of the connection steel claw, unable to enter into the electrolyte, belongs to the natural oxidation part, through the optimization of molding machine mould reduce oxidation, reduce the weight of anode carbon block, at the same time, through technical innovation to improve equipment reliability.



After the mold optimization of Pre-Baked Carbon Anode, the total weight of anode carbon block was reduced by 18.44kg, among which the weight of the bottom four corners was reduced by 7.41kg from the strip edge to the round edge, the weight of the side four edges was reduced by 2.01kg, and the weight of the carbon block was reduced by 9.02kg after the upper convex block was optimized.The change of assembly method of screw shaft and bearing improves the reliability of the equipment and avoids the falling off of screw bearing.By optimizing the die of anode carbon block, it can not only reduce the weight of anode carbon block, save the cost, but also improve the reliability of the equipment.The optimized aluminium anode consumption can reduce 8.5 kg/t ist Al, according to the annual output of 120000 tons/year aluminium electrolytic a workshop production, carbon block unit price 2800 / ton, lower costs 2.958 million yuan
