Abstract
The invention provides a method for connecting an electrolytic aluminum anode without pouring. In the method, a steel talon is manufactured into a wedge shape with a big end down cross section; the cross section of an anode carbon block is made into a boss shape, and a dovetail through slot is formed in the middle of the upper plane of the anode carbon block along the vertical direction; after the steel talon is put in the dovetail through slot, steel plates with the same number and same thickness are filled in gaps on two sides of the steel talon correspondingly, so that the two sides of the steel talon and the copper plates are closely jointed, and the two steel plates and the anode carbon blocks on two sides are closely jointed. The pouring connecting method of melting ferro-phosphorus is changed into a wedge plate compacting connecting method, an intermediate frequency furnace for melting ferro-phosphorus and pressure-disengaging equipment for disengaging a phosphorus iron hoop by pressure are canceled, so that the equipment investment is reduced, the labor intensity is reduced, and the working environment is improved; the profile steel talon is put in the dovetail through slot of the carbon block and compacted by a wedge-shaped stainless steel plate without pouring, so the operation is easy and convenient; and the conventional mode of combining the anode steel talon and the anode carbon block is changed, a transitional connecting mode of combining copper and carbon is adopted, so that the conductive contact area is enlarged, and the anode conductive drop can be effectively reduced.
Description
Technical field
The present invention relates to a kind of method of attachment of anode block and steel pawl in Aluminum Electrolysis Production.
Background technology
In Aluminum Electrolysis Production, anode is as one of raw materials for production, and ton aluminium consumption is very big.In order to produce needs, general electrolytic aluminium factory all is with the ferrophosphorus juice that melts anode block to be cast in the steel pawl both at home and abroad now.This mode of connection that adopts, energy expenditure is big, ton aluminium cost height, labour intensity is big, and labor condition is poor.Anode in use, electric current is that the ferrophosphorus by cast conducts to anode block because that ferrophosphorus contacts with anode block is bad, the pressure drop that has strengthened whole electric installation has increased energy consumption.Simultaneously, after anode block used, when cleaning steel pawl, took off a ferrophosphorus ring Asia that also needs handle to be cast on the steel pawl, and time-consuming, again contaminate environment.
Summary of the invention
The purpose of this invention is to provide a kind of new electrolytic aluminium anode carbon piece and the method for attachment of steel pawl, to overcome the problem that prior art exists.
Realize that the technical scheme that the object of the invention is taked is: the steel pawl is made cross section little wedge shape, and wedge shape is asymmetric for big down; It is boss shape that anode block is made cross section, in middle, last plane, longitudinally open a swallow-tail form groove, the less side of swallow-tail form groove two side angle and steel pawl angle equates, the cross section of swallow-tail form groove is greater than the cross section of steel pawl, after the steel pawl is put into the swallow-tail form groove, correspondence is inserted quantity and is equated in the space of steel pawl both sides, the copper coin that thickness is identical, in the bigger side of steel pawl angle, between steel pawl and each copper coin, insert a stainless steel clapboard identical, between steel pawl two sides and copper coin and stainless steel clapboard with the space angle, between stainless steel clapboard and the copper coin, fit tightly between two copper coins and the both sides anode block.
For preventing that anode block from crackle occurring after being depleted to a certain degree, on the boss on anode block top, jig is installed, boss is clamped from both sides.
Described jig is made up of clamp, clamping web plate, push bolt, and two clamps are located at respectively and clamp the web plate two ends, and clamp at one end is provided with push bolt.
For making things convenient for the stainless steel clapboard to be pressed into, there is a vertical surface at the one side middle part that steel pawl gradient is bigger.
Positively effect of the present invention is: changing fusing ferrophosphorus cast method of attachment is that clapboard compresses method of attachment, has cancelled the intermediate frequency furnace of fusing ferrophosphorus and the pressure-off equipment of pressure-off ferrophosphorus ring, has reduced facility investment, has reduced labour intensity, has improved Working environment; The deformed steel pawl is put into the swallow-tail form groove of carbon piece, compresses with the wedge shape stainless steel plate, need not pour into a mould, and is easy and simple to handle; Change existing anode steel jaw and anode carbon block steel carbon combination, adopt copper carbon in conjunction with excessive ways of connecting, it is long-pending to increase conductive contact surfaces, can effectively reduce the anode conducting volts lost.
Description of drawings
Accompanying drawing 1 is for adopting the present invention with steel pawl and vertical view after anode block is connected; Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to sectional view.
Embodiment
As shown in Figure 2, steel pawl 1 is made cross section for going up little wedge shape down greatly, and wedge shape is asymmetric, left side angle is 1.5 °, the right angle is 3 °, it is boss shape that anode block 2 is made cross section, in middle, last plane, longitudinally open a swallow-tail form groove 8, the less side of swallow-tail form groove 8 two side angles and steel pawl angle equates, the cross section of swallow-tail form groove 8 is greater than the cross section of steel pawl 1, after steel pawl 1 is put into swallow-tail form groove 8, correspondingly in the space of steel pawl 1 both sides put into the identical copper coin 4(of three thickness as shown in Figure 1), in the bigger side of steel pawl 1 angle, between steel pawl 1 and each copper coin 4, insert a stainless steel clapboard 5 identical, between steel pawl 1 two sides and copper coin 4 and stainless steel clapboard 5 with the space angle, between stainless steel clapboard 5 and the copper coin 4, fit tightly between two copper coins 4 and the both sides anode block 2.For making things convenient for stainless steel contract template 5 to be pressed into, there is a vertical surface 7 at the middle part of the one side that steel pawl 1 gradient is bigger; For preventing that anode block 2 from crackle occurring after being depleted to a certain degree, on the boss on anode block 2 tops, the both sides of steel pawl guide rod install a jig respectively, jig is made up of clamp 9,10, clamping web plate 3, push bolt 6, two clamps 9,10 are located at respectively and clamp web plate 3 two ends, clamp 9 at one end is provided with push bolt 6, and rotatably compressing bolt 6 can clamp boss from both sides.
