Abstract
The utility model discloses a phosphorus pig iron-casted cathode assembled carbon block. According to the electrolytic principle and the current distribution requirement, two sections of steel bars and a continuous steel bar are selected; a non-conducting filling material exists in the cathode carbon blocks of the steel bar sections and the continuous steel bar corresponding to the centre joint of two anodes; the same non-conducting filling material exists in the other position except the projection position of the anode; at the manual leg stretching position, the advance model is adopted; and the model shape is set according to the function of y=x2 parabola. According to the novel phosphorus pig iron-casted cathode assembled carbon block disclosed by the utility model, the current density of the cathode can be improved by 5-7%, and the problem that the phosphorus pig iron-casted cathode tank has insufficient heat capacity is solved effectively. The conductivity of the manual leg extending position is reduced from inside to outside gradually, so that an effective furnace upper part is formed conveniently and protect the manual stretching leg is protected, and furthermore the double aims of realizing good energy-saving and consumption-reducing index and prolonging the service life of the aluminum electrolytic cell can be achieved.
Description
Technical field
the utility model 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
the utility model provides a kind of phosphorus pig iron casting negative electrode assembling charcoal piece; Reach to improve current density and be convenient to form effective stove and help; 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.
The technical scheme of the utility model 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; Non-conductive packing material is arranged, and the anode orthographicprojection has same non-conductive packing material with external position; Be shaped as function y=x in the manual work position moulding of stretching one's legs

reach to improve current density and be convenient to form effective stove and help, and protect manual work to stretch one's legs, and realize good index and the raising aluminium cell life-span dp of saving energy and reduce the cost.
The novel phosphorus pig iron casting negative electrode assembling charcoal piece of
the utility model 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.
