Abstract
The invention relates to a method for demoulding a vibro-moulding aluminum electrolytic electrode carbon block. The method is characterized in that the demoulding process is carried out after the vibratory compaction of the carbon block, a weight drop is lifted to the height that the carbon block is not right compacted by the weight drop in advance; then the mould is moved upward for demoulding; after the mould is completely separated from the carbon block, the weight drop is again lifted to the preset height, thus finishing the demoulding process. The method for demoulding the vibro-moulding compacted aluminum electrolytic electrode carbon block of the invention is also characterized in that the weight drop is lifted in two steps, after the weight drop is limited by contacting the upper part of the carbon block in the demoulding process after the advance lift, and no gravity is exerted on the carbon block, thus the stress caused by carbon block deformation in the demoulding process is avoided. The method effectively avoids crack resulting from decrease in cathode (anode) carbon blocks in the vibratory compaction process of prebaked cathode (anode) blocks for electrolytic aluminum.
Description
Technical field
The present invention relates to a kind of release method of electrolysis of aluminum electrode carbon piece of vibratory compaction.
Background technology
In the Aluminium Electrolysis process, the carbon piece is to use as consumable material-the moon (sun) utmost point, and its common preparation process is: feedstock production-calcining-middle comminution powder-batching-mix and pinch-vibratory compaction-cooling-roasting-finished product; Wherein vibratory compaction is one of important procedure of carbon product production, and it is to the carbon product product performance person of opening crucial effects.Vibratory compaction can not only make the carbon piece have the geometric shape of desired specification and rule, also can make simultaneously some physicalies of carbon piece, as density, physical strength, porosity, uniformity and electroconductibility etc. to a certain degree improvement, the performance of cloudy (sun) utmost point carbon piece directly has influence on the quality of electrolytic aluminum.
When the moon (sun) utmost point carbon block forming, the separating effect of mould and carbon piece has fundamental influence to carbon piece quality, if the disengaging weak effect between mould and the carbon piece, then possible: 1, frictional force between the two is excessive, then mould takes up certain altitude with the carbon piece, and carbon piece and mould break away from suddenly then, drops on the shaking table, the carbon piece crackle occurs or internal stress is excessive after the demoulding, becomes waste product after directly becoming waste product or roasting; 2, along with the application aborning of large-scale the moon (sun) utmost point carbon piece, when mould separates with the carbon piece after the vibratory compaction, form and to break away from the middle of the carbon piece and all around because frictional force and along with mould promotes, form the lower arcuate surface distortion of carbon piece when causing the demoulding, it is big or crackle occurs to separate the internal stress of back carbon piece.
At present, adopting the technology of the demoulding is that weight is risen to predetermined height, and mould rises then, carries out the demoulding, before each moulding to mould inner side brush oil.But this way has its bigger shortcoming: 1, all need before the moulding each time manually mould inner side brush oil, workload is bigger, influences automatic production; 2, this method can only be improved its disengaging effect, can not thoroughly solve the influence that the demoulding causes the carbon piece; 3, oil smoke is big, severe operational environment.
Summary of the invention
Purpose of the present invention is exactly the problem that exists at above-mentioned prior art, provide a kind of the lower arcuate surface distortion that overcomes formation carbon piece when determining carbon piece and the mould disengaging suddenly or the demoulding can be arranged, cause the carbon piece crackle to occur or internal stress is excessive, the release method of the electrolysis of aluminum electrode carbon piece of the vibratory compaction of the phenomenon that yield rate reduces.
The objective of the invention is by the following technical programs.
A kind of release method of electrolysis of aluminum electrode carbon piece of vibratory compaction, it is characterized in that its knockout course is after carbon piece jolt ramming moulding, earlier weight is promoted to the height that the charcoal piece just is not subjected to weight weight in advance, again with the capable demoulding of shift-in on the mould, after treating that mould and carbon piece break away from fully, promote weight again to predetermined height, finish knockout course.
The present invention is a kind of release method of electrolysis of aluminum electrode carbon piece of vibratory compaction, it is characterized in that described elder generation is promoted to weight after the charcoal piece just is not subjected to the height of weight weight to be the jolt ramming of carbon piece in advance, owing to weight and mould promote the recovery of elasticity amount that makes weight on the shaking table reduce caused shaking table vibroshock and since the lifting of weight and on the carbon piece because pressure disappears this recovery of elasticity amount sum on short transverse of caused carbon piece.
The release method of the electrolysis of aluminum electrode carbon piece of a kind of vibratory compaction of the present invention, weight promotes in two steps, weight is pre-promote after, weight contacts with charcoal piece top and spacing during the demoulding, but agravic applying pressure on the charcoal piece can not cause to produce the phenomenon that the distortion of charcoal piece produces stress in the knockout course.Prevented that effectively electrolgtic aluminium prebake the moon (sun) utmost point carbon piece from reducing the phenomenon that cloudy (sun) utmost point carbon piece cracks in vibratory compaction.
Embodiment
A kind of release method of electrolysis of aluminum electrode carbon piece of vibratory compaction, its knockout course is after carbon piece jolt ramming moulding, earlier weight is promoted to the height that the charcoal piece just is not subjected to weight weight in advance, again with the capable demoulding of shift-in on the mould, after treating that mould and carbon piece break away from fully, promote weight again to predetermined height, finish knockout course.Described elder generation is promoted to weight after the charcoal piece just is not subjected to the height of weight weight to be the jolt ramming of carbon piece in advance, owing to weight and mould promote the recovery of elasticity amount that makes weight on the shaking table reduce caused shaking table vibroshock and since the lifting of weight and on the carbon piece because pressure disappears this recovery of elasticity amount sum on short transverse of caused carbon piece.After pre-lift height is the jolt ramming of carbon piece and since weight and mould promote the recovery of elasticity amount that makes weight on the shaking table reduce caused shaking table vibroshock and since the lifting of weight and on the carbon piece because pressure disappears caused carbon piece recovery of elasticity amount sum on short transverse originally.
