Abstract
The utility model relates to a crimp device for large-scale pre-baked anode aluminum electrolytic cells and cathode square steels, which comprises a cathode square steel block (1), a crimp copper (2) of the steel, and an annealed aluminum bus-bar (6). The utility model is characterized in that the crimp copper (2) connected with the cathode square steel block (1) and the aluminum plate (3) connected with the annealed aluminum bus-bar are directly exploded into a composite body. The utility model not only overcomes the defects of steel welding technique and the serious damages to production caused by frequent power failures, but also solves the world technical difficulty of metal welding in strong magnetic fields. Compared with the prior art, each set of the crimp device has a less weld joint. For example, each 300 KA electrolytic cell has 104 fewer weld joints, thus the voltage drop is reduced accordingly. The utility model has the advantages of fewer welding and crimp points, low contact voltage drop, low power consumption, low production cost, low fieldwork mounting workload and low labor intensity, simple structure, easy mounting operation and reliable performance.
Description
Technical field
The utility model relates to large-sized prebaked cell for aluminum-reduction negative electrode square steel crimp technology device.
Background technology
Along with the continuous development of China's electrolytic aluminum industry, continuous upgrading China of technology has become world aluminum big producing country, adopts the above aluminium cell of 160KA to become China's aluminium industrial expansion main flow.Between recent years, domesticly generally adopt super-huge aluminium cell to strengthen China's aluminium industry competitive power in the world.Run into this global problem of steel disc welding technique between the negative electrode square steel and the soft band of negative electrode under the high-intensity magnetic field condition simultaneously.The welding scheme of present domestic employing is adopt to reduce potline current to 200KA or the welding of power failure way when electrolytic cell overhaul, so not only causes enormous economic loss and energy dissipation to enterprise, has also restricted China's aluminium industrial expansion.The crimp technology of domestic existing solution is copper al blasting piece and connector presser secondary welding technology, and this technical disadvantages is that weld seam is many, the electric current contact pressure drop is big, production cost is high.
Summary of the invention
The purpose of this utility model provides and a kind ofly need not reduce potline current or power failure when the overhaul electrolyzer, does not influence the large-sized prebaked cell for aluminum-reduction negative electrode square steel compression bonding apparatus of ordinary production.
The purpose of this utility model is achieved through the following technical solutions: large-sized prebaked cell for aluminum-reduction negative electrode square steel compression bonding apparatus comprises negative electrode square steel and negative electrode square steel crimping copper coin, soft aluminium busbar, it is characterized in that negative electrode square steel crimping copper coin that is connected with the negative electrode square steel and the aluminium sheet that is connected with soft aluminium busbar directly explode to connect to be combined into one.Promptly adopt an explosive welding composite molding of copper sheet and aluminium flake.
Large-sized prebaked cell for aluminum-reduction negative electrode square steel compression bonding apparatus of the present utility model had both overcome steel disc and had been welded to connect the defective of technology and the serious harm that frequently has a power failure production is caused, and had solved the unweldable global problem of the metal under the high-intensity magnetic field again.Every casing pressure tipping is put than prior art and is lacked weld seam one, and for example every 300KA electrolyzer just can lack 104 road weld seams, and volts lost reduces.The utility model weld, crimping point lack, and contact drop is low, and power consumption is low, and production cost is low.Little and the labour intensity of on-site installation work amount is low, and have simple in structure, easy for installation, advantages such as dependable performance.
