Study of Parameters of Electrodispersion of SSu3 Alloy Waste

The purpose of this study is to study the influence of the parameters of an experimental installation for electroerosive dispersion, namely, the voltage at the ends of the electrodes, the frequency of electrical pulses and the capacity of discharge capacitors on the productivity of the process of obtaining the charge of the SSu3 alloy of the acid battery plate

Methods. To carry out the study, a number of experiments were performed on an experimental installation for electroerosive dispersion (. The dispersion process was carried out at the following installation parameters: voltage 100– 200 V, 25.5.–65.5 UF, 25–75 Hz, constant parameters in this study were: the distance between the electrodes  100 mm, dispersion time 300 min. On this equipment, a charge of lead-antimony alloy was obtained in the form of powder. Then the resulting charge was weighed on a laboratory scale "MASSA K", model VK-1500. 

Results. During the study, it was found that the productivity of the charge in the form of lead-antimony alloy powder is higher when the indicator of the variable parameter is higher. When changing the pulse repetition frequency, the maximum powder output was obtained at the highest frequency parameter – 75 Hz. Also in the course of the study, the dependence of the powder yield during the electrodispersion of the lead-antimony alloy SSu-3 with such an installation parameter as the voltage on the electrodes was established, with the same values of frequency and capacitance, it is noted that the higher the voltage index, the higher the productivity of the process, and, accordingly, the production of lead-antimony powder. A study of the performance of lead-antimony powder when changing the capacitance parameter of discharge capacitors showed a direct relationship, the largest powder yield is achieved at the maximum allowable capacity of discharge capacitors at this installation – 65.5 UF.

Conclusion. The obtained results can be used for further study and improvement of the composition and structure of the alloy, as well as for the selection of optimal operating modes of the installation in further studies.
