Abstract

The invention relates to the technical field of carbon anode heat insulation structures, in particular to a carbon anode heat insulation cover plate and a manufacturing method and a using method thereof. Raw materials of the carbon anode heat insulation cover plate comprise water glass, powder containing metallic aluminum and aluminum oxide, auxiliaries and water. When an anode needs to be replaced, by dismounting the anode heat insulation cover plate corresponding to the anode scrap needing to be replaced, the anode scrap can be lifted out of an electrolytic cell, then a new carbon anode is placed in the electrolytic cell, and finally the dismounted carbon anode heat insulation cover plate is restored. Through the steps, after the carbon anode heat insulation cover plate is used for insulating heat for the carbon anode, the heat loss is reduced, the procedures of replacing the carbon anode can be simplified, compared with existing procedures of replacing the carbon anode, the procedures such as material picking, shell breaking, block fishing, material covering and anode scrap cleaning are omitted, the anode replacing time is greatly shortened, the anode replacing workload is reduced, the current efficiency is improved, and the production cost is greatly lowered for enterprises.

Description

technical field [0001] The invention relates to the technical field of carbon anode heat preservation structures, and relates to a carbon anode heat preservation cover plate and its manufacturing method and use method. Background technique [0002] With the rapid development of my country's electrolytic aluminum industry, the unit production scale of electrolytic cells is getting larger and larger, and the demand for using alumina as a carbon anode covering material is increasing. When alumina is used as a carbon anode covering material, since alumina is bulk material , when the electrolyzer is used for a period of time, the aluminum oxide as the covering material is easy to crust, and when it is used again, the crust must be crushed, thereby increasing the labor intensity of the workers. When the anode (carbon anode) has worked in the electrolytic cell for a certain period (usually 30 days to 40 days), the anode needs to be replaced, that is, the residual electrode is taken ...
