Abstract
The utility model relates to a steel claw for an aluminum electrolysis prebaked anode, which comprises four claws. The utility model is characterized in that the end surface of an upper cross beam of the steel claw for the aluminum electrolysis prebaked anode is symmetrically lengthened by 30mm in the direction towards the outside, R20 circular arc transition is added outside the claw according to the circular arc symmetry, the lower end of a symmetrical line of the first claw and the fourth claw is inclined by 5mm towards the outside, the bottom end of the first claw and the fourth claw has the conicity of 15/30, the width of cross section of the upper cross beam of the steel claw is 100mm, and the height is 160mm. Compared with the prior art, the utility model has the advantages that the investment is low, the design does not need additional investment, and only a little change is needed to be carried out on the original mold. The length of the steel claw is lengthened, the heat radiation area of the upper part of the steel claw is enlarged, the heat storage quantity of the cross beam of the steel claw is effectively reduced, the steel claw does not have obvious elastic deformation in the use period, any alignment and cutting welding are not needed, the work intensity is greatly reduced, the operation efficiency is improved, the service life of the steel claw is prolonged, and the energy consumption is effectively reduced.
Description
Technical field
The utility model relates to used for aluminium electrolysis prebaked anode production technical field, particularly a kind of used for aluminium electrolysis prebaked anode steel pawl.
Background technology
Pre-baked anode steel grab is indispensable parts during electrolyzer is produced, and along with the develop rapidly of aluminium industry, prebaked cell is with very fast replacement past backwardness, high energy consumption, with serious pollution self-roasting tank, and the usage quantity of pre-baked anode steel grab will constantly enlarge.Pay attention to the problem that pre-baked anode steel grab occurs in the production use, the way of seeking to solve, thereby the operational efficiency of raising Aluminum Electrolysis Production.
Bending deformation is the difficult problem that aluminum electrolysis industry faces in the pre-baked anode steel grab, the stably manufactured of aluminum electrolysis industry, aspect such as enhance productivity and save energy and reduce the cost are all caused disadvantageous effect, each manufacturing enterprise has all found out many ways and has solved and handle, and does not overlap the terms of settlement that everybody is satisfied with but search out one at present as yet.Several terms of settlement that present each corporate boss will adopt have: (1) changes whole deformed steel claw; (2) change interior curved pawl head method; (3) curved pawl head method in the cut-out; (4) the alignment welding process is severed in the part; (5) steel pawl straightener.But the whole bag of tricks is defectiveness all, or has increased the pressure drop of steel pawl, or efficient is lower or the like, therefore all can not satisfy economy, principle efficiently.In the steel pawl there be the major cause of bending deformation: the rigidity of (1) steel pawl crossbeam is not enough, is recycling about 12～15 all after dates, and bending deformation is excessive in producing gradually under the effect of hot environment and charcoal piece gravity, and can't use; Specific volume is less mutually with the inside upper part entity for (2) two outer pawl outer upper crossbeam entities, asymmetric, inboard quantity of heat storage is more than outside quantity of heat storage, and outside end face area of dissipation is inboard big, make that inboard speed of cooling is slow than the outside, when shrinking, outside cooling, aggravated the interior bending deformation of steel pawl during inner arc cooling simultaneously with the inboard plasticity compression of the condition of high temperature.
Summary of the invention
The purpose of this utility model provides a kind of used for aluminium electrolysis prebaked anode steel pawl, and steel pawl structure and size are innovated improvement, under the situation that does not increase any labour intensity and other energy consumption, preferably resolves problem on deformation curved in the steel pawl.
The technical solution of the utility model is:
Used for aluminium electrolysis prebaked anode steel pawl upper beam end face symmetry direction lengthening 30mm laterally, increase end face entity volume, improve end face heat accumulation area, the relative heat accumulation that dwindles the outside in 1, the 4 pawl upper beam is poor, cooling speed is poor outside reducing in the pawl, reaches the purpose of bending deformation in reducing; Increase the arc transition of R20 according to the inner arc symmetry in the pawl outside, to strengthen outer arc pulling force relative equilibrium in the pawl; 1,4 pawl symmetric line upper ends is remained unchanged (30mm), and the lower end 5mm that tilts laterally provides the reversible deformation surplus when curved in 1,4 pawls, and 1,4 pawl bottoms are 15: 30 tapering, to increase the reversible deformation surplus; For improving the steel pawl in hot rigidity down, reduce under the condition of high temperature because of four paws antianode load-bearing unbalance stress and deadweight distortion, the increase current channel increases to 100mm with steel pawl upper beam cross-sectional dimension (from 80mm); Highly (from 140mm) increases to 160mm.
The utility model compared with prior art has following positively effect:
1. less investment, the design need not extra investment, only needs do slightly to change to original mould to get final product.
2. the extended length of steel pawl has increased the area of dissipation on steel pawl top, effectively reduces the quantity of heat storage of steel pawl crossbeam.
3. steel pawl of the present utility model does not have tangible elastic deformation in life cycle, need not do any alignment and cut weldering, has reduced labour intensity greatly, improves operational efficiency, and the life cycle that has prolonged the steel pawl effectively reduces energy consumption.

Embodiment
Used for aluminium electrolysis prebaked anode of the present utility model steel pawl upper beam end face symmetry direction lengthening 30mm laterally, increase end face entity volume, improve end face heat accumulation area, the relative heat accumulation that dwindles the outside in 1, the 4 pawl upper beam is poor, cooling speed is poor outside reducing in the pawl, reaches the purpose of bending deformation in reducing; Increase the arc transition of R20 according to the inner arc symmetry in the pawl outside, to strengthen outer arc pulling force relative equilibrium in the pawl; 1,4 pawl symmetric line upper ends is remained unchanged (30mm), and the lower end 5mm that tilts laterally provides the reversible deformation surplus when curved in 1,4 pawls, and 1,4 pawl bottoms are 15: 30 tapering, to increase the reversible deformation surplus; For improving the steel pawl in hot rigidity down, reduce under the condition of high temperature because of four paws antianode load-bearing unbalance stress and deadweight distortion, the increase current channel increases to 100mm with steel pawl upper beam cross-sectional dimension (from 80mm); Highly (from 140mm) increases to 160mm.
