Prebaked-anode template for aluminium electrolysis and preparation and forming technology thereof

Abstract

The invention relates to a prebaked-anode template for aluminium electrolysis and a preparation forming technology thereof, belonging to the technical field of kneading forming technology. The prebaked-anode template mainly comprises a template base plate and a pulling ejection device. The prebaked-anode template is characterized in that the right-angled template of the template base plate of the prebaked-anode template is set to be a chamfer template, a plurality of grooving plates used for the grooving of the bottom of the prebaked-anode are arranged on the upper surface of the template base plate longitudinally or transversely, the grooving plates have the flat-plate structure, corresponding demoulding grooves are arranged on the pulling ejection device according to the height and width of the grooving plates of the template base plate; the prebaked-anode template and the pulling ejection device can be prepared according to the above structure, the quality of the anode is optimized and increased; and the ton aluminum prebaked-anode consumption can be effectively reduced. The O2, CO2 and CO gases generated in the electrochemical reaction process of electrolysis can be effectively removed and the sudden anode effect caused by gas separation can be avoided. The wettability of the molten cryolite electrolyte to the shoe pole surface of the anode can be well maintained so that powerful current can smoothly pass through the electrolytic bath. The power consumption and carbon consumption of the electrolytic aluminium are reduced, thus reducing the exhaust emission in the aluminium electrolysis process and the pollution to the atmospheric environment.

Description

technical field [0001] The invention belongs to the technical field of prebaked anode kneading molding for electrolytic aluminum. Background technique [0002] Since Guizhou Aluminum Plant introduced Nikkei's first prebaked anode forming production line in 1980, to the mid-1990s, my country's prebaked anode forming technology can be summarized into one stage; to the beginning of this century, domestic aluminum prebaked anode vibration Machinery manufacturers, combined with international successful advanced technology experience, have also produced aluminum prebaked anode vibration forming machines with similar vibration forming methods. For example, a rotary three-position forming machine is used; Luoyang Vibration Machinery Manufacturing Factory; Shenyang Borida Engineering Machinery Company, two vibration forming machines manufactured; 1. The bottom palm of the anode is flat, without slots, and without chamfers. 2. The anode is the heart of electrolysis, and the quality of...

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a prebaked anode template for electrolytic aluminum and its manufacturing process to solve the problem that the bottom palm of the prebaked anode in the prior art is flat, which is prone to produce a large amount of slag. As a result, the consumption of the anode is increased; a large amount of anode slag enters the molten electrolyte, which increases the viscosity and uncleanness of the molten electrolyte; destroys the technical conditions of the aluminum electrolysis process; correspondingly increases the consumption of electric energy and the loss of prebaked anodes, etc. question
