Abstract
The invention discloses an anode seamless grouting method used for reducing iron carbon pressure drop. According to the anode seamless grouting method, graphite powder and kerosene are mixed at a ratio of 3:10-1:2 so as to obtain a conductive slurry; and the conductive slurry is delivered into seams between ferrophosphorus rings and charcoal bowls. Compared with the prior art, the anode seamless grouting method is capable of reducing per ton aluminium technology AC power consumption 54kwh, reducing production cost greatly, and increasing enterprise profits; and is another electrolytic aluminium energy-saving production innovative technology following a series of low-temperature low-voltage energy-saving production innovative technology developing application such as abnormal shape cathode, grille type anode, and small electrode production.
Description
Technical field
The present invention relates to a kind of grouting method, be specifically related to a kind of seamless grouting method of anode reducing iron carbon pressure and fall.
Background technology
In recent years, the technological innovation that domestic electrolyzing aluminum industry is advanced by leaps and bounds shows, the difference between the actual power consumption of highly energy-consuming Aluminum Electrolysis Production and theoretical power consumption is likely constantly reduced by the innovative technology of many-sided multi-angle.Through long-term constantly exploration discovery, at present, after anode carbon block and steel pawl pass through phosphorus pig iron casting, ferrophosphorus liquid cooling meat, together with there will be between ferrophosphorus ring with charcoal bowl and not easily by the gap that it is found that, add top casting cavity, on average 75ml water can be held in the cavity, gap existed in each charcoal bowl group, air is poor conductor, the iron carbon pressure that the existence in this gap can increase aluminium guide bar group undoubtedly falls, reduce the conductance of anode system, that is, I monotechnics personnel have been found by creative work: the gap between ferrophosphorus ring and charcoal bowl, it is the major reason reducing anode system conductance.
Summary of the invention
For the problem that ferrophosphorus ring in prior art and the gap that occurs between charcoal bowl cause the iron carbon pressure increasing aluminium guide bar group to fall, the invention provides a kind of seamless grouting method of anode reducing iron carbon pressure and fall, the method greatly reduces iron carbon pressure and falls.
Technical scheme of the present invention realizes in the following manner: a kind of seamless grouting method of anode reducing iron carbon pressure and fall, it comprises the gap between ferrophosphorus ring and charcoal bowl, adopt Graphite Powder 99 and kerosene to be mixed into conductive paste according to the ratio of 3:10 ~ 1:2, then conductive paste is poured in the gap between ferrophosphorus ring and charcoal bowl.
Described Graphite Powder 99 and kerosene mix according to the ratio of 1:3 ~ 1:2.
Described Graphite Powder 99 and kerosene mix according to the ratio of 4:11.
Compared with prior art, for 400KA level aluminium cell, after carrying out back-grouting by conductive paste, test channel carbon pressure reduces to 85.2mv, than the 103.33mv before experiment, reduces 18.13mv, fallen 17.5% on a year-on-year basis, the every mv generally acknowledged with industry falls 3kwh electricity and calculates
A ton aluminium technique ac consumption 54kwh can be reduced, the specially-shaped cathode that continues, grid type anode, the another item electrolytic aluminum production energy-saving innovative technology since a series of low temperature low voltage production energy-saving innovative technology research and development applications such as low pole span production, greatly save production cost, add the profit of enterprise.

fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of seamless grouting method of anode reducing iron carbon pressure and fall, it comprises the gap 3 between ferrophosphorus ring 1 and charcoal bowl 2, adopts Graphite Powder 99 and kerosene to be mixed into conductive paste according to the ratio of 3:10 ~ 1:2, then conductive paste is poured in the gap between ferrophosphorus ring and charcoal bowl.
Further restriction, Graphite Powder 99 and kerosene mix according to the ratio of 1:3 ~ 1:2.
As preferably of the present invention, Graphite Powder 99 and kerosene mix according to the ratio of 4:11, farthest can reduce iron carbon pressure and fall.
