Abstract
Experimental samples of steel-copper and copper composite conductors, including those from copper waste, were obtained according to the developed technology. The physical and operational properties of the copper composite material were investigated, special attention was paid to the wear resistance, which was tested as part of the working pantograph of the electric train, and the electrical conductivity of the obtained copper composite was investigated. It is shown that the electrical conductivity of the composite material made of copper is higher in the range of operating temperatures of the pantograph, and the wear resistance is much higher than that of the sample made of standard copper material.

Summary
Получены экспериментальные образцы сталемедного и медного композиционного проводника в том числе и из отходов меди по разработанной технологии. Исследованы физические и эксплуатационные свойства медного композиционного материала, особое внимание обращено на износостойкость, которую проверили в составе рабочего пантографа электрички, исследовали электропроводность полученного медного композита. Что электропроводность композиционного материала из меди выше в области рабочих температур пантографа, а износостойкость значительно выше, чем у образца из стандартного медного материала. Анализ публикаций по математическому моделированию процесса формирования непрерывнолитой, как и полунепрерывнолитой медной заготовки свидетельствует об их разнородности и немногочисленности, а наличия моделей описания процесса затвердевания сталемедной заготовки, получаемой в процессе взаимодействии расплава меди со стальной вставкой не выявлено.
