Abstract

The invention discloses a production method of an aluminum electrolysis continuous prebaked anode. The method comprises a bonding method of stud nut adjustable hollow filling, molten aluminum pouring-mechanical composite steel claws, a new anode carbon block and an old anode carbon block and a heat preservation mode for cooperative use of the stud nut adjustable hollow filling, molten aluminum pouring-mechanical composite steel claws and the anode carbon blocks. According to the production method, the old anode carbon block is consumed, the new anode carbon block is connected and then consumedagain, another new anode carbon block is connected in a circulating mode, so that the production of the continuous prebaked anode is realized, the resistivity of an anode assembly is reduced, hollowfilling, molten aluminum pouring and mechanical composite steel claws and the anode carbon blocks are are convenient to use, the bonding of the new anode carbon block and the old anode carbon block isfirm and reliable, the resistance between the new anode carbon block and the old anode carbon block is small, the electrolysis energy consumption is reduced, the residual electrode is eliminated, theconnection is convenient and safe, the heat insulation effect is good, the heat energy loss is small, the power consumption of an electrolytic cell can be greatly reduced, and the production cost islow.

Description

Technical field

[0001] The invention relates to a production method and structure of an aluminum electrolysis continuous prebaked anode, belonging to the technical field of aluminum electrolysis continuous prebaked anode. Background technique

[0002] 1. In the existing pre-baked anode electrolytic aluminum production, the anode steel claws and the anode carbon block are all connected by phosphorus pig iron casting. On the upper surface of the pre-baked anode carbon block in the conductive direction, there are 2 to 4 with a diameter of 160-180mm , A round groove with a depth of 80~110mm, commonly known as a carbon bowl. When the anode is assembled, the carbon bowl is used to place the anode claw head. The anode claw head is cast in the carbon bowl with phosphorous pig iron. The steel claw head and the aluminum conductive rod pass through the aluminum Steel explosion welding connection, so that the anode conductive rod and the anode carbon block are connected as a whole to form th...
