Abstract
Belonging to the technical field of aluminum electrolysis, the invention especially relates to an anode ledge elimination agent and a use method thereof. Technically, the invention aims to provide an agent able to raise ledge temperature and eliminate ledge through temperature rise. In order to solve the problem, according to the provided technical scheme, the elimination agent comprises the following components by weight: 1-5% of NaF, 5-50% of Al2O3, 5-70% of Al, 1-20% of LF, 1-20% of KF, 1-5% of Fe, and 1-5% of SiO2. After adding the elimination agent to a ledge part, the ledge temperature can be raised, the electrolyte liquid temperature at the ledge can be lowered, and the degree of superheat between the electrolyte body and the ledge can be increased, thus promoting rapid melting of the ledge.
Description
Technical field
The invention belongs to technical field of aluminum electrolysis, relate in particular to a kind of anode stretch one's legs digestive pharmaceutical and using method thereof.
Background technology
The burner hearth of Hall-Ai Lu aluminium cell is the important component part of electrolytic cell, is the basic of whole electrolytic process. ButAlong with applying of Low Voltage Technique, electrolytic cell heat income reduces, and generally presents bight cooler, and electrolyte is a large amount of in bightSolidify, the bight phenomenon of growing up of stretching one's legs, causes electrolytic cell burner hearth deformity, and horizontal current increases, and affects electrolytic cell stability and electricityStream efficiency. And the easy bending anode bus of stretching one's legs greatly, has a strong impact on the normal operation of electrolytic cell.
Process at present the way of stretching one's legs and have corner insulation method and artificial treatment method. Corner insulation method is by strengthening outside bightInsulation is melted and is stretched one's legs, and its keeping warmth space is little, stretches one's legs and is difficult to fusing; Artificial treatment method is that anode is put forward will stretch with overhead traveling crane afterwardsLeg is destroyed, and this method exists drawback: itself firm and infusibility of, stretching one's legs, and overhead traveling crane is difficult to thoroughly process; Two, process the process of stretching one's legsTime is longer, and labor workload is large, and causes a large amount of thermal loss; Three, artificial treatment weak effect, after processing, a period of time stretchesLeg can be grown up again repeatedly, and the problem of stretching one's legs cannot be effected a radical cure.
