Abstract

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.

利用电塑性效应实现拉丝机电传动的研究

分析各种测试，检查通过模具的线材，以增加其可塑性，提高毛坯质量。在计算和实验数据的基础上，比较了在连续式马弗炉中通过动线直接输送电流产生给定温度分布和通电加热时的能耗。在相应的数学模型上对每种方法的加热参数进行了数学建模。应用数学模型是基于热方程的边值问题。为了证实数学模型的充分性，在加热区控制点进行了温度测量的实验研究。对拉丝过程中产生电塑性效应的脉冲电流加热线材参数进行了计算。研究结果表明，为了提高拉拔过程中线材的塑性，宜采用脉冲电流。
