Abstract
The invention discloses a phosphorus pig iron cast negative electrode assembled carbon block. According to an aluminum electrolysis theory and a current distribution demand, two sections of steel sticks and a through long steel stick are selected; negative electrode carbon blocks of the two sections of steel sticks and the through long steel stick are opposite to centre joints of two positive electrodes; a non-conductive material is used for filling; the non-conductive material is used for filling the parts outside the positive projections of the positive electrodes; at a manual leg extension position, advanced shaping is adopted; and the shape is set according to a parabolic function y=x<2>. According to the phosphorus pig iron cast negative electrode assembled carbon block, the current density of the negative electrode is improved by 5 to 7 percent, and the problem that the heat capacity of the phosphorus pig iron cast negative electrode tank is insufficient is solved; the conductivity of the manual extended leg position is gradually reduced from inside to outside, so that an effective furnace upper is formed; and therefore, manual extended leg is protected; and dual purposes of obtaining high energy saving and consumption reduction indexes and prolonging the service life of an aluminum electrolytic cell are realized.
Description
Technical field
the present invention relates to technical field of aluminum electrolysis, specifically a kind of aluminum electrolyzing cell used phosphorus pig iron casting negative electrode assembling charcoal piece.
Background technology
along with the fast development of aluminium electrolytic industry, 200KA, 300KA, 400KA, and even design of 500KA grooved and application have obtained tremendous development.Energy consumption and carrying capacity of environment are seriously restricting the Sustainable development of aluminium industry.Got into since 21st century, exploitation of specially-shaped cathode electrolysis tech and application effectively improve electrolysis of aluminum utilization of power efficient.Full greying phosphorus pig iron technology is at home and abroad progressively promoted, and has further improved energy-saving and cost-reducing level.From beginning in 2008, the domestic full graphitized cathode carbon block of aluminium sector application that has, to planar cathode charcoal piece phosphorus pig iron casting test, ton aluminium direct current consumption is reduced to 12680 kwh from 13300 kWh.But also because specially-shaped cathode and negative electrode phosphorus pig iron casting charcoal piece have favorable conductive efficient, cause conducting electricity less demanding place, electrical efficiency is very good, has quickened the negative electrode loss, and manual work is stretched one's legs and do not formed effectively protection, causes the aluminium cell early damage.
Summary of the invention
the purpose of this invention is to provide a kind of phosphorus pig iron casting negative electrode assembling charcoal piece, reach to improve current density and be convenient to form effective stove group, and the protection manual work is stretched one's legs, and realizes good energy-saving and cost-reducing index and improves aluminium cell life-span dp.
Technical scheme of the present invention is: according to electrolysis of aluminum principle and distribution of current needs; Select two sections rod irons and elongated rod iron; Two sections rod irons and elongated rod iron cathode carbon pieces are at two anode centre joint correspondence positions; Take the better non-conducting material of plasticity to fill, the same better non-conducting material of plasticity that adopts is filled beyond the anode orthographicprojection; In the manual work position of stretching one's legs, adopt moulding in advance, the moulding shape is pressed function y=x

Para-curve is provided with.Reach to improve current density and be convenient to form effective stove and help, protect manual work to stretch one's legs, realize good index and the raising aluminium cell life-span dp of saving energy and reduce the cost.
novel phosphorus pig iron casting negative electrode assembling charcoal piece of the present invention can improve 5-7% with cathode current density, effectively solves the not enough problem of phosphorus pig iron casting cathode can thermal capacity.The manual work position conductivity of stretching one's legs is from inside to outside and progressively reduces state, helps forming effective stove group, and the protection manual work is stretched one's legs, and realizes good energy-saving and cost-reducing index and improves aluminium cell life-span dp.
