Abstract
The utility model relates to an anode carbon block for a pre-baked aluminum electrolytic cell, which is mainly applied to the production of the pre-baked aluminum electrolytic cell and the production of the anode carbon block. The anode carbon block for the pre-baked aluminum electrolytic cell is characterized in that seven to ten ferro-phosphorus ring cable-stayed grooves are arranged in a prefabricated carbon bowl at the upper part of the anode carbon block; the horizontal projective planes of the ferro-phosphorus ring cable-stayed grooves are over 15mm in width and are over 13mm in depth. In the production process of the aluminum electrolytic cell, by adopting the technical scheme of increasing the number of the cable-stayed grooves of the prefabricated carbon bowl of the anode carbon block and widening the dimensions of the depth and the width of the cable-stayed grooves, not only can the conduction contact area of the anode carbon block and a ferro-phosphorus ring be increased and the ferro-carbon contact voltage drop be reduced, but also the connecting strength between an anode steel claw and the anode carbon block can be improved.
Description
Technical field: a kind of pre-calcining electrolytic cell is mainly used in the production of pre-calcining electrolytic cell and the production of anode block with the anode anode block.
Technical background: be configured with the prefabricated carbon bowl of several phosphorus pig iron rings that are used to cast on the existing general anode carbon block for aluminium electrolysis tank, realize being connected with the conduction of anode steel jaw head.In order to improve the bonding strength between ferrophosphorus ring and the anode block, prevent that it from coming off, on anode block ready-formed carbon bowl peripheral side wall, be configured with the little groove that tiltedly draws that six roads slightly tilt.The width of horizontal projection that this six road is little tiltedly to draw groove is about 12 millimeters, and the degree of depth is about 12 millimeter.
Existing general anode carbon block for aluminium electrolysis tank has following shortcoming, and the one, after the diameter of carbon bowl was confirmed, the thermal interface contact area of ferrophosphorus ring and carbon bowl was less, caused the volts lost of iron carbon contact higher; The 2nd, the strength of joint of ferrophosphorus ring and anode block carbon bowl is lower, is prone to cause coming off between ferrophosphorus ring and the anode carbon bowl; The 3rd, along with the increasing of anode block volume and weight, the little design strength of joint of the carbon bowl of groove that tiltedly draws in above-mentioned six roads can not adapt to large-scale aluminum electrolytic cell development and the energy-saving and cost-reducing needs of producing.
Summary of the invention:, improve strength of joint and conductivity between anode block and the anode steel jaw in order to overcome the above-mentioned defective of general at present anode carbon block for aluminium electrolysis tank carbon bowl design.The present invention has designed a kind of novel aluminum electrolyzing cell used prebaked anode carbon piece.
A kind of pre-calcining electrolytic cell with the characteristic of anode anode block is; Structure is provided with 7 to 10 road ferrophosphorus rings tiltedly to draw groove, its ferrophosphorus ring tiltedly to draw the width of the horizontal plane of groove is more than the 15mm on the prefabricated carbon bowl in the top of anode block, and the degree of depth is more than the 13mm.
According to technique scheme, a kind of pre-calcining electrolytic cell has arc transition with the rib point position of the intersecting lens of the horizontal plane that tiltedly draws groove of the prefabricated ferrophosphorus ring carbon bowl of anode anode block.
In the aluminium cell production process; Adopting the present invention to add the prefabricated carbon bowl of anode block tiltedly draws groove quantity and widens the size technologies scheme that it tiltedly draws depth of groove and width; The conductive contact surfaces that not only can improve anode block and ferrophosphorus ring is long-pending; Reduce the contact drop of iron carbon, can also improve the strength of joint between anode steel jaw and the anode block.
Description of drawings: a kind of pre-calcining electrolytic cell of the present invention is then more clear through embodiment and description of drawings with anode anode block structural design scheme and constructional feature.
The sectional drawing of Fig. 1 anode block.
The existing general anode block fragmentary top plan view of Fig. 2.
The fragmentary top plan view of Fig. 3 aluminum anode carbon of the present invention piece.
Shown in its figure: 1 anode block, 2 prefabricated carbon bowls, 3 tiltedly draw groove
Specific embodiments: a kind of pre-calcining electrolytic cell of the present invention is that the carbon bowl of antianode carbon piece on existing basis undergoes technological transformation with anode anode block characteristics; To be arranged on the ferrophosphorus ring that is used on the anode block cast improves; The groove that tiltedly draws that soon designed originally in the carbon bowl strengthens intensification; And by 6 original roads be increased to 7 to more than, and realize increasing iron carbon contact area with this, improve the purpose of iron carbon bonding strength.Changing carbon welding bell tool in the generalized case download anode carbon block forming technology gets final product.
Like Fig. 1, shown in Figure 3, be configured with 8 roads on the carbon bowl on the anode block and tiltedly draw groove, tiltedly draw groove to Duo twice than 6 roads in the original design existing general anode block carbon bowl.It is more than the 16mm that its ferrophosphorus ring tiltedly draws the width of the horizontal plane of groove, and the degree of depth is that the rib point position of intersecting lens of the horizontal plane that tiltedly draws groove of the above carbon bowl of 13mm has arc transition.
Claims (2)
1. a pre-calcining electrolytic cell is used the anode anode block, it is characterized in that: being configured with 7 to 10 road ferrophosphorus rings on the carbon bowl of anode block, tiltedly to draw groove, its ferrophosphorus ring tiltedly to draw the width of the horizontal plane of trench recess be more than the 15mm, and the degree of depth is more than the 13mm.
2. use the anode anode block according to the described a kind of pre-calcining electrolytic cell of claim 1, it is characterized in that; Ferrophosphorus ring tiltedly draws on the stupefied point in the horizontal plane angle of trench recess and has little arc transition.
