Abstract
The utility model relates to a cathode shaped steel bar for aluminum electrolytic bath. It is characterized in that the shaped steel bar face is of small diameter in the head near to the bath lateral side; along the center of the bath, the bar surface increases in diameter gradually; the enlarged end of bar surface is embedded with a pylome. The utility model increases the effective contact area of the steel bar and the cathode carbon which are combined firmly. The distribution of electric current is improved in the cathode steel bar.
Description
Technical field
The utility model relates to a kind of aluminum electrolyzing cell used specially-shaped cathode rod iron.
Background technology
Cathode steel bar is the carrier in the aluminum cell current lead-in groove.Present cathode steel bar mainly contains two kinds of square rod iron and rectangle rod irons.The characteristic dimension of square rod iron sectional area is 200mm*200mm, is detected in part small pre-calcining groove at present.The characteristic dimension of rectangle rod iron sectional area is 65mm*180mm, is the principal mode of present aluminum electrolyzing cell used cathode steel bar, and a charcoal piece is placed two row's rod irons, is the improvement of the single rod of square shaped.
Present cathode steel bar has the following disadvantages: effective contact area of a, rod iron and cathode carbon pieces is less.B, rod iron shape are single, and be not enough with cathode carbon pieces bonded tightness degree.C, from the center of electrolyzer to sidepiece, the distribution of current inequality.More than 3 cause the iron charcoal contact drop between present cathode carbon pieces and rod iron higher.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned prior art, provides effective contact area of a kind of rod iron and cathode carbon pieces big, with the cathode carbon pieces bonded is tight, distribution of current equal, the low aluminum electrolyzing cell used specially-shaped cathode rod iron of iron charcoal contact drop between cathode carbon pieces and rod iron.
To achieve these goals, the utility model by the following technical solutions.
Aluminum electrolyzing cell used specially-shaped cathode rod iron is characterized in that being shaped as near groove sidepiece rod iron head of its cathode steel bar is little, the plate shape rod iron that increases gradually to the groove center direction, and on the plate face of the increase end of rod iron, have the through hole of perforation.
Aluminum electrolyzing cell used specially-shaped cathode rod iron of the present utility model is characterized in that the ship that is shaped as of its cathode steel bar is starched shape.
Aluminum electrolyzing cell used specially-shaped cathode rod iron of the present utility model is characterized in that being shaped as of its cathode steel bar is trapezoidal.
Aluminum electrolyzing cell used specially-shaped cathode rod iron of the present utility model is an abnormity, and is little near groove sidepiece rod iron head, increases gradually to the groove center direction; Various stress deformations on the suffered horizontal direction are evenly distributed on the whole rod iron.Owing to increase near the middle part contact area, can improve electric current distribution situation on cathode steel bar.Have the up/down perforation hole on the plate face, increased effective contact area of rod iron and cathode carbon pieces, reduced iron charcoal contact drop, rod iron is tightr with combining of cathode carbon pieces, has improved electric current distribution situation on cathode steel bar.

Embodiment
Aluminum electrolyzing cell used specially-shaped cathode rod iron, being shaped as near groove sidepiece rod iron head of its cathode steel bar is little, the plate shape rod iron 1 that increases gradually to the groove center direction, and on the plate face of the increase end of rod iron, have the through hole 2 of perforation.
During use, rod iron rod iron head small end is taken shape in cathode carbon pieces place near the groove sidepiece, the big end of rod iron rod iron head takes shape in the cathode carbon pieces, and the various stress deformations on the horizontal direction that cathode carbon pieces is subjected to are evenly distributed on the whole rod iron.Owing to increase near the middle part contact area, can improve electric current distribution situation on cathode steel bar.Have the up/down perforation hole on the plate face, increased effective contact area of rod iron and cathode carbon pieces, reduced iron charcoal contact drop, rod iron is tightr with combining of cathode carbon pieces, has improved electric current distribution situation on cathode steel bar.
Claims (3)
1. aluminum electrolyzing cell used specially-shaped cathode rod iron is characterized in that being shaped as near groove sidepiece rod iron head of its cathode steel bar is little, the plate shape rod iron that increases gradually to the groove center direction, and on the plate face of the increase end of rod iron, have the through hole of perforation.
2. aluminum electrolyzing cell used specially-shaped cathode rod iron according to claim 1 is characterized in that the ship that is shaped as of its cathode steel bar is starched shape.
