Abstract
The invention relates to an anode for aluminum electrolysis for solving the problems like poor binding force of an anode pellet and an anode steel stud, large resistance, high power consumption and anode shedding. The invention provides a double-gate energy-saving anode. The double-gate energy-saving anode comprises an anode, pellets and gates. The pellets and gates are located on the anode. The gates are arranged around each pellet in a form of a non-circumferential ring. Each gate has an inner diameter of 100-250 mm, an outer diameter of 150-400 mm and a central angle of 10-120 degrees. The double-gate energy-saving anode of the invention increases the effective contact area and binding force of the anode pellets and the steel stud, decreases the resistance of the parts, reduces the iron-carbon pressure drop, reduces the power consumption, and prevents the occurrence of anode shedding accident.
Description
Technical field
The present invention relates to anodes used in aluminum electrolysis, be specifically related to the energy-saving anode of a kind of double cast gate.
Background technology
The anodes used in aluminum electrolysis of prior art is imitative rectangular parallelepiped, top be provided with ball several, the degree of depth of ball is generally about 110mm, anode steel jaw is fixed with the casting of phosphorus pig iron liquid in ball, ball place suitable for reading is provided with the circumference type pouring gate of enlarged diameter, the height of pouring gate is generally about 10mm, the structure formation of this pouring gate increases the trend that anode ball becomes up big and down small, the bonding force of anode ball and anode steel jaw leg is deteriorated, anode steel jaw leg can be made time serious to shake in anode ball, this position resistance value is increased, power consumption is finally caused to increase, even there will be de-pole accident.
Summary of the invention
The object of the present invention is to provide the energy-saving anode of a kind of double cast gate, effectively can solve anode ball and the problem such as anode steel jaw leg bonding force is poor, resistance value is large, power consumption is high, de-pole.
Technical scheme of the present invention realizes in the following manner:
The energy-saving anode of a kind of double cast gate, it comprises anode and the ball that is positioned on anode and cast gate, and described cast gate is that the annulus of on-circular is distributed in around ball, and the internal diameter of cast gate is 100 ~ 250mm, and external diameter is 150 ~ 400mm, and central angle is 10 ° ~ 120 °.
Further, the internal diameter of restriction cast gate is 160mm, and external diameter is 260mm, and central angle is 60 °.
Further, limit cast gate and have 1.
Further, limit cast gate and have 2.
Further, 2 cast gates are limited symmetrical.
Further, the diameter of restriction ball is 160mm, and the degree of depth is 110mm.
Adopt technique scheme, the invention has the advantages that: the effective contact area and the bonding force that increase anode ball and steel pawl leg, reduce the resistance value at this position, reduce the iron-charcoal pressure drop at this position, reduces power consumption, and anti-anti-avulsion pole accident occurs.
