Abstract
The invention relates to structure technology of a steel bar group of a cathode block., which has a biggest difference from the universal steel bar group of the cathode block at present that: only one cathode steel bar is arranged in a steel bar groove of the cathode block; and the two sides of a steel bar are both provided with steel bar ramming pastes which are connected with the cathode block. Compared with the prior art, the novel steel bar group of the cathode block adopts a new technical scheme that: two cathode steel bars are arranged in the steel bar groove; the steel bar ramming pastes are arranged between two steel bars, and the outer side faces of the two cathode steel bars are connected with the cathode block through a high-resistant conductive adhesive. The novel steel bar group of the cathode block is used for constructing a cathode lining of an aluminium electrolysis cell and can greatly reduce contact voltage of iron and carbon so as to achieve the aim of reducing power consumption of structural resistance of the aluminium electrolysis cell.
Description
Technical field
A kind of novel cathode carbon piece rod iron group is used building by laying bricks or stones of pre-calcining electrolytic cell electro-conductive liner for cathode.
Technical background
Cathode block and cathode steel bar are the main conductive material components of building electro-conductive liner for cathode of aluminium-electrolytic cell by laying bricks or stones, the two existing general combination is, open two rectangle steel bar troughs along its length in the cathode block bottom, a negative electrode is just excellent on putting in the middle of again in the rectangle steel bar trough, the gap about about 15mm is respectively left between cathode steel bar both sides and the rectangle steel bar trough and top, do packing material with special carbon element of graphite rod iron paste between its gap, adopt and manually make firm by ramming in a down-to-earth manner with pneumatic facility, cathode steel bar and cathode block are fitted together, as the conductive component of aluminum cell cathode inner lining.
Existing general in the cathode block steel bar trough, the cathode block rod iron group of solid rod iron ramming paste is pricked in both sides, be used for building by laying bricks or stones of cathode lining of electrolytic bath, main drawback is: the thickness of ramming paste is thicker, rod iron is stuck with paste fugitive constituent and is overflowed after the roasting, and porosity increases, rod iron stick with paste material self than resistance value height, cause the volts lost of cathode lining of electrolytic bath bottom land to increase, average iron carbon contact drop reaches about 125mV.Cause the Aluminum Electrolysis Production power consumption to increase.
Summary of the invention
In order to overcome now general cathode block rod iron group, iron carbon touch voltage depreciation is too high between cathode steel bar and the cathode block, the shortcoming that resistivity is bigger than normal the present invention proposes a kind of new iron carbon that can reduce between cathode block and the cathode steel bar in conjunction with the design structure scheme of contact drop.
A kind of technical scheme of novel cathode carbon piece rod iron set constructor is: in the steel bar trough of cathode block bottom two cathode steel bars are set along its length, cathode block and junction, cathode steel bar interface use high-temperature electric conduction glue as the interface junction condensation material, adopt the rod iron ramming paste as packing material in the middle of two rod irons, cathode block and cathode steel bar are configured to cathode block rod iron group.
Adopt a kind of novel cathode carbon piece rod iron group of this technical scheme structure, because iron carbon interface is in conjunction with having adopted conductivity to be better than the conductive resin of rod iron paste as iron carbon bond material, shortened the conduction distance between the iron carbon, reduced between the two the interface in conjunction with resistance, be used for building by laying bricks or stones of aluminum cell cathode inner lining, the contact drop of iron carbon is significantly reduced.Thereby reach the purpose that reduces the power consumption of cell construction resistance.

A kind of novel cathode carbon piece rod iron set constructor gives further specifying in year in conjunction with the accompanying drawings and embodiments.
Fig. 1 is the facade structural map of a kind of novel cathode carbon piece rod iron set constructor embodiment.
Fig. 2 is the I of a kind of embodiment of Fig. 1---the I sectional drawing.
Shown in its figure:
1 cathode block, 2 cathode steel bars, 3 rod iron ramming pastes, 4 conductive resins, 5 steel bar troughs.
Specific embodiment
A kind of novel cathode carbon piece rod iron its technical scheme of group such as accompanying drawing Fig. 1, shown in Figure 2, distinguishing with the maximum that shows general cathode block rod iron group is that a cathode steel bar (2) only is set in same cathode block (1) steel bar trough (5) in the past, all there is rod iron ramming paste (3) rod iron (2) both sides, are connected with cathode block (1).And new solution adopts is two cathode steel bars (2), and rod iron ramming paste (3) is arranged in the middle of two rod irons (2), and what the outer side of two cathode steel bars (2) adopted is that resistant to elevated temperatures conductive resin (4) is connected with cathode block (1).
Conductive resin between the iron carbon (4) necessarily has resistance to elevated temperatures, adopts resin as in conjunction with cakingagent usually, and adopting Graphite Powder 99 or boron carbide powder is that aggregate is made, and is applied to during use on cathode steel bar (2) and cathode block (1) bonding surface after the rust cleaning.
The construction technology of rod iron ramming paste (3) is basic identical with existing general technical matters.
Claims (1)
1. a novel cathode carbon piece rod iron group is formed by cathode block (1), cathode steel bar (2), rod iron ramming paste (3) structure, it is characterized in that: in cathode block (1) bottom steel bar trough (5), last two cathode steel bars (2) are set along its length, cathode block (1) and cathode steel bar (2) junction, interface use high-temperature electric conduction glue (4) as the interface junction condensation material, adopt rod iron ramming paste (3) as packing material in the middle of two rod irons (2), cathode block (1) and cathode steel bar (2) are configured to cathode block rod iron group.
