Abstract
The invention discloses a vertical charging method for roasting carbon blocks, relating to the technical field of production of pre-baked anodes for electrolytic aluminium. The method comprises the following steps: after laying fillers by a multifunctional overhead crane, placing a charging die (3) on the fillers; laying the fillers in a fillers filling area (4) of the charging die again; subsequently pulling the fillers out of the charging die; and arranging raw carbon blocks (1) organized in groups at the spacing of the fillers that are laid again. The invention also discloses a charging die (3) that is used for the vertical charging method for roasting carbon blocks. The charging die (3) is grid-shaped and all grids are arranged alternately; the large grids are carbon black containing areas (5); and the small grids are filler filling areas (4). The method and the die effectively solve the problems of corner collapse, edges collapse and the like of the roasting carbon blocks in the vertical charging process, thus improving the qualified rate of the roasting finished product, and reducing production cost.
Description
Technical field
The present invention relates to electrolgtic aluminium prebaked anode production technical field, be specifically related to the method and the shove charge mould thereof of the vertical shove charge of a kind of burning carbon piece.
Background technology
Along with the fast development of China's aluminium industry, drive the carbon element production scale and constantly enlarge, automaticity improves constantly, and the multifunction crane technology is constantly perfect, and the baking carbon blocks furnace structure also constantly develops towards narrower, darker direction.
At present the carbon element factory adopts large-scale open type roasting mode, and the roaster charging mode also has original dress for sleeping in to change upright dress into, and to be that every hopper is upright adorn three layers of livings carbon piece to upright dress charging mode, seven every layer, is provided with the 45o rib for ease of its end of the demoulding during living carbon block forming.Adopt upright dress promptly can improve the unit production capacity and can improve the coefficient of overall heat transmission again, reduce the unit consumption index.Yet, since multifunction crane lifting when giving birth to the packaged stove of carbon seven be one group, edges and corners, adjacent two carbon pieces bottom form the dead angle, make inserts can not effectively be filled into edges and corners, carbon piece end; In the roasting process, give birth to the carbon piece and be heated coal pitch of agglomerant is moved, cause edges and corners, carbon piece end after the roasting arrisdefect to occur easily, fall phenomenon such as rib, form the piece that gives up, directly influence the baking carbon blocks qualification rate, cause energy waste.
Summary of the invention
Burning carbon piece edges and corners formed dead angle, arrisdefect and fall problem such as rib when technical problem to be solved by this invention provided the vertical shove charge of a kind of effective solution, and then raising roasting product qualified rate, reduce production costs the shove charge mould of packaged stove method of the carbon of energy savings and use.
The present invention solves its technical problem and adopts following technical scheme:
The method of the vertical shove charge of burning carbon piece of the present invention, be after multifunction crane is with the inserts lay, on inserts, place the shove charge mould again, at the inserts fill area of shove charge mould lay inserts once more, pull out the shove charge mould afterwards, place the living carbon piece of marshalling at the inserts interval of secondary lay.
Be better implement the invention, before multifunction crane lay inserts, will give birth to the charcoal piece and organize into groups.
When implementing the method for the vertical shove charge of burning carbon piece of the present invention, required shove charge mould is a lattice-shaped, and big or small lattice are alternately arranged successively, and described big lattice are carbon piece rest area, and described little lattice are the inserts fill area.
After adopting this mould to implement according to above-mentioned shove charge method, can be directly at place, dead angle, adjacent two livings carbon piece ends, lay inserts in advance, guarantee the packaged stove of life carbon after, unsettled phenomenon does not appear in the end corner angle.Give birth to the carbon piece in roasting process, during the softening migration of pitch, the end corner angle have inserts to support, and the carbon piece is not easy to form and falls rib, make burning carbon piece end arrisdefect, fall rib and the probability that produces useless piece reduces more than 90%.
Description of drawings
Fig. 1 organizes into groups the structural representation of charcoal piece for the present invention;
Fig. 2 is the structural representation of shove charge mould of the present invention;
Among the figure: 1, give birth to the carbon piece; 2, lead angle; 3, shove charge mould; 4, inserts fill area; 5, carbon piece rest area.
The specific embodiment
In conjunction with Fig. 1, at first will give birth to the carbon piece and organize into groups, specifically be that seven living carbon pieces are one group, yi word pattern is arranged, and per two living carbon piece 1 edges and corners form lead angle 2; Adopt multifunction crane at the indoor lay inserts of roaster afterwards; In conjunction with Fig. 2, on inserts, place shove charge mould 3,, pull out shove charge mould 3 afterwards at the inserts fill area 4 of shove charge mould 3 lay inserts once more, at the inserts interval of lay once more is that carbon piece rest area 5 is placed the living carbon piece of finishing group, carries out the shove charge roasting.
The shove charge mould 3 that adopts in the present embodiment is lattice-shaped, and big or small lattice are alternately arranged successively, and big lattice are carbon piece rest area 5, and little lattice are inserts fill area 4.By at inserts fill area 4 lay inserts once more, make inserts effectively be filled into edges and corners, carbon piece end, become useless piece thereby avoid two charcoal piece edges and corners, burning carbon piece bottom to form the dead angle, thereby improved the baking carbon blocks qualification rate, saved the energy.
Claims (3)
1. the method for the vertical shove charge of a burning carbon piece, it is characterized in that: be after multifunction crane is with the inserts lay, on inserts, place shove charge mould (3), at the inserts fill area (4) of shove charge mould lay inserts once more, pull out the shove charge mould afterwards, place the living carbon piece (1) of marshalling at the inserts interval of lay once more.
2. the method for the vertical shove charge of burning carbon piece according to claim 1 is characterized in that: before multifunction crane lay inserts, will give birth to charcoal piece (1) and organize into groups.
3. when implementing the method for the vertical shove charge of the described burning carbon piece of claim 1, it is characterized in that: required shove charge mould (3) is a lattice-shaped, and big or small lattice are alternately arranged successively, and described big lattice are carbon piece rest area (5), and described little lattice are inserts fill area (4).
