Abstract
Техническое решение относится к области обработки металлов давлением, в частности к изготовлению проволоки методом ее многократного волочения. Техническим результатом является повышение микросплошности поверхности проволоки, ее прочности, ее электропроводности, а также снижение затрат на изготовление проволоки. Технический результат получен электротехнической проволокой из алюминиевого сплава, содержащей сердечник и расположенный вокруг него упрочненный слой микросплошности, полученный пластической деформацией поверхности проволочной заготовки, плотность и микросплошность упрочненного слоя больше плотности и микросплошности сердечника. Сплав содержит железо, кремний, церий, лантан, празеодим, алюминий. Предусмотрен способ изготовления проволоки, характеризующийся тем, что осуществляют холодное волочение проволочных заготовок через калиброванный волок, проводят отжиг и естественное охлаждение заготовок в холодной печи, имеющую температуру окружающей среды, далее разогревают в печи до 350-450°С и выдерживают в нагретом состоянии. После заготовки остужают и сваривают их концы, образуя длинную плеть, которую подвергают волочению, причем изложенный цикл обработки плети проволочной заготовки проводят многократно.The technical solution relates to the field of metal forming, in particular to the manufacture of wire by the method of its repeated drawing. The technical result is to increase the microsurface of the wire surface, its strength, its electrical conductivity, as well as reducing the cost of manufacturing wire. The technical result was obtained by an electrical wire made of aluminum alloy, containing a core and a reinforced micro-continuity layer located around it, obtained by plastic deformation of the surface of the wire blank, the density and micro-continuity of the reinforced layer are greater than the core density and micro-continuity. The alloy contains iron, silicon, cerium, lanthanum, praseodymium, aluminum. A method of making wire is provided, characterized in that cold drawing of wire blanks is carried out through calibrated fiber, annealing and natural cooling of billets in a cold furnace having an ambient temperature is carried out, then heated in a furnace to 350-450 ° C and kept in a heated state. After the workpiece is cooled and their ends are welded, forming a long whip, which is subjected to dragging, and the described loop processing cycle of the wire blank is carried out repeatedly.
