In the production of aluminum electrolysis plant, anode is known as "the heart of electrolysis", and the casting quality of anode phosphorus pig iron directly affects the high and low power consumption of tons of aluminum. In the process of casting phosphorus pig iron, due to the differences in the formula, casting process and casting level of phosphorus pig iron, the electrode assembly quality will be greatly different, which is manifested in the difference of electrode power consumption after assembly. Especially in the production practice of large-scale pre-baked aluminum electrolytic cell, the current intensity is generally large, and the voltage drop (even if it is very small) at each place is also a large number for a long time. How to reduce the casting voltage drop of phosphorus pig iron and reduce the loss of "black" voltage is an important index to achieve the fine production of electrolytic aluminum. In addition, in the production and assembly of the anode steel claw, due to the differences in the material itself of the molten steel claw and the structural steel claw, or the differences in the casting process, welding process, and the level of implementation personnel, the final result is a huge difference in the quality of the anode steel claw. Bad casting and welding steel claw, which has large resistance and poor conductive ability, will cause high loss in the later production process, resulting in a large amount of electricity wasted, reducing the economic benefits of the plant. Improving the anode steel claw body voltage drop and weld voltage drop also has a great significance of energy saving and consumption reduction.

    Therefore, it is necessary to develop an online equipment that can detect and reflect the casting quality in time. Combining years of experience in developing equipment for the aluminum industry, Zhengzhou Jingwei Technology Industry Co., Ltd. has developed JW-1802E anode assembly quality on-line tester, which is designed by adopting high-precision constant-current power supply technology, measurement technology, infrared temperature measurement technology, and embedded software technology, and is able to accurately measure the casting quality. With accurate measurement, convenient operation and stable performance, this online device is a targeted inspection system for anode assembly workshop.

    Real-time and comprehensively reflect the production quality of this anode assembly production plant. According to the change of casting quality, when there is a big casting voltage drop, it will give a feedback to the process links to check the problem timely to avoid quality problems in the production line batch

    It can lay the foundation for the fine management of digital factory. The groups are classified according to different inspection results and different voltage drops detected. And in the subsequent electrolysis workshop when changing the electrodes, the anodes with the same voltage drop range are changed into the electrolysis cells with the same voltage drop range, so as to improve the current equalization of the anodes and the smoothness of the electrolysis cells' operation.
