Research of Electric Drive of Drawing Mill with Implementation of Electroplastic Effect

Analyzed various tests to check the wire that moves through the die to increase its plasticity and improve the quality of the hairs. Based on the calculated and experimental data, a comparison was made of energy consumption when creating a given temperature distribution by direct transmission of electric current through a moving wire and its heating in a continuous muffle furnace. Mathematical modeling of the heating parameters of each method is performed on the corresponding mathematical model. The applied mathematical model is based on the boundary value problem for the heat equation. To confirm the adequacy of the mathematical model, experimental studies were carried out with temperature measurements at the control points of the heating zone. Calculations were made of the parameters of wire heating by pulsed current, which forms the electroplastic effect during drawing. According to the results of the study, it was found that in order to increase the plasticity of the wire during the drawing operation, it is advisable to use a pulsed current.
