Description
Technical Field
The invention relates to the technical field of electrolytic aluminum anode steel claws, in particular to a mechanical composite steel claw with adjustable bolt and nut, hollow pouring and aluminum water pouring.
Background
In the existing production of electrolytic aluminum of a prebaked anode, an anode steel claw and an anode carbon block are all connected in a phosphorus pig iron casting mode, 2-4 circular grooves with the diameter of 160-180 mm and the depth of 80-110 mm are arranged on the upper surface of the prebaked anode carbon block in the conducting direction and commonly called as a carbon bowl, when the anode is assembled, the carbon bowl is used for placing an anode claw head, the anode claw head is cast in the carbon bowl by phosphorus pig iron, the steel claw head and an aluminum conducting rod are connected through aluminum steel explosion welding, and thus the anode conducting rod and the anode carbon block are connected into a whole to form an anode carbon block assembly.
In a phosphorus pig iron casting type connection, the temperature at which phosphorus pig iron is cast will be approximately 1700 ℃, although phosphorus pig iron is the smallest expansion coefficient in steel. But still much greater than the expansion coefficient of the carbon block. The phosphorus pig iron has an expansion coefficient of about 15 to 16 x 10-5Degree, expansion coefficient of the carbon block is 3.7-4.0 multiplied by 10-6The difference between the concentration of phosphorus and the concentration of carbon is more than thirty times, so that a certain gap is formed between the contraction of the phosphorus pig iron on the electrolytic cell and the carbon bowl, and the voltage drop between the phosphorus pig iron and the carbon bowl is about 150 mV.
The existing anode steel claw is integrally cast by molten steel and has a solid structure. Consists of steel claw head (connected with explosive sheet), steel claw beam and 2-8The steel claw foot is a solid cylinder, and the resistivity is higher, causing the current empty consumption too big. The largest production cost of electrolytic aluminum is electricity charge, the main raw material of the anode steel claw at present is A3 steel, and the resistivity of A3 steel adopted by the anode steel claw at present is 20 multiplied by 10 at normal temperature-8Ohm. m, and the resistivity of aluminum is 2.82 x 10-8Meter, the resistivity of aluminum is 14.1% of a3 steel; when the temperature is raised to 800 ℃ in the production process, the resistivity of the anode steel claw of the A3 steel is 118 multiplied by 10-8Ohm. meter, while the resistivity of aluminum is 12.39 x 10-8Ohm. meter, it can be seen that at 800 ℃, the resistivity of aluminum is only 10.5% of that of a3 steel. The prior anode component consists of an aluminum guide rod, an explosion sheet, an anode steel claw, phosphorus pig iron cast in a carbon bowl and an anode carbon block. In the electrolytic aluminum production process, the pressure drop between an aluminum guide rod and a transverse bus of an electrolytic cell is 27mv, the pressure drop of the aluminum guide rod is 11mv, the pressure drop of an explosion piece is 36mv, the pressure drop of a steel claw is 13mv, the pressure drop between phosphorus pig iron and a carbon bowl is 150mv, the pressure drop of an anode carbon block is 140mv, the total pressure drop of the whole anode assembly is 377mv, and the current power consumption per ton of aluminum is about 13000 degrees. The electric loss of the existing anode assembly reaches 1225 degrees/ton, and the anode assembly has huge electricity-saving potential.
The applicant of the invention reforms the anode steel claw and the anode carbon block on the basis of applying a series of continuous anode patents, and the continuous anode carbon block does not need to consume the carbon block to be very thin, so that the anode steel claw does not need to be worried about high-temperature ablation, deformation and damage.
The present inventor previously invented a common problem of a steel claw linked by a T-shaped and L-shaped fastening bolt and a flat frame and a flat rotating shaft of a cast-mechanical composite steel claw (the T-shaped patent is 201610104972.4, the L-shaped patent is 201610526791.0, and the frame and linkage patent is 201710088066.4). The device has no adjusting capability, and can not adapt to the fatal problems that the carbon block level and the guide rod are vertical and cannot be considered due to various deformation, low connecting precision, large weight, large size and the like of the anode guide rod, the steel claw and the carbon block. The requirement for the levelness of the carbon block and the verticality of the guide rod in the continuous prebaked anode electrolytic aluminum production is determined by objective production requirements. Generally, when the new carbon block and the old carbon block are butted, after the guide rod is locked, the horizontal maximum gap of the new carbon block and the old carbon block is preferably less than 2 mm. Deformation of the carbon block and large size of the anode steel claw assembly with the guide rod cause the problems of deformation of the aluminum guide rod and the steel claw in the using process.
The T-shaped and L-shaped fastening bolts are used for fastening the conductive surfaces of the carbon block and the steel claw and are responsible for rigid connection of the carbon block and the steel claw, and the adjusting function of adjusting the levelness of the carbon block and the verticality of the guide rod is not achieved in design principle and design idea.
As is known to all, the design of the steel claw does not simply consider the structure of the steel claw, the change of the structure of the steel claw is bound to the change of the structure of the carbon block, and further influences the change of a plurality of links such as the forming and the manufacturing of the carbon block, the design of the structure of the steel claw also needs to overcome a plurality of steel claws invented by the inventor in the past, and the requirements of electrolytic production on the final assembly precision of the carbon block, the steel claw and a guide rod assembly cannot be really met.
In conclusion, the existing prebaked anode technology and the continuous prebaked anode technology have the problems of high voltage drop and large electric loss of the anode assembly in the electrolytic production process. The existing various steel claws have no capacity of adjusting both the levelness of the carbon block and the verticality of the guide rod, can not really meet the requirement of continuous prebaked anode production on the final assembly precision of the carbon block, the steel claws and the guide rod assembly, and can not be popularized and used.
