At present, the quality inspection of the assembly of iron carbon modules in electrolytic cells is estimated by using a DC welding machine to conduct high current testing, as the current output is unstable. So the measurement results cannot intuitively reflect the assembly quality of the module. The iron carbon voltage drop tester jointly developed and produced by our company and China Aluminum Corporation adopts new power electronics technology, with a large current output, up to 2000A. The instrument adopts a 6-inch touch screen. Intelligent operation. Users only need to set the test current, and the instrument automatically outputs a high current through the program. When the set current is reached, the device automatically measures the resistance and voltage drop of the module, thereby quickly and accurately determining whether the module assembly is qualified.

The quality of the electrodes (anode carbon block, cathode carbon block) in the electrolytic cell has a significant impact on various economic indicators after the electrolytic cell is put into operation. When assembling electrodes, significant differences in the quality of electrode assembly are ultimately caused by differences in the materials themselves (mainly cathode paste, pig iron phosphate), or differences in assembly processes and the assembly level of assembly personnel. Electrodes with poor organizational quality have high resistance and poor conductivity, resulting in high losses in the later production process, causing a large amount of electrical energy to be wasted and reducing the economic benefits of the factory. In addition, improving the welding quality of electrode steel rod heads and reducing the pressure drop of the weld seam are also of great significance for energy conservation and consumption reduction.

This instrument can directly measure the resistance and voltage drop after electrode assembly, and display the experimental current, resistance, and voltage drop on the LCD screen. This instrument measures accurately, is easy to operate, and has stable performance, making it a highly targeted instrument. Users can timely and conveniently grasp the detailed data of electrode assembly through this instrument, thereby judging the quality of assembly, making it easier to correct assembly materials or modify assembly processes in a timely manner, and strengthening the control of assembly quality.

SFTW-200AThe iron carbon pressure drop tester can directly detect the assembly quality of iron carbon modules (anode carbon block, cathode carbon block) and steel rod head welding, thus selecting qualified iron carbon modules can save users a lot of electricity costs.Using customized testing lines and fixtures to make testing more convenient and fast. Reduced the workload of frontline workers.
