Claims (1)

Способ производства контактных проводов, включающий получение расплава, его легирование, вытяжку литой заготовки и формирование из нее методом пластической деформации требуемого профиля провода, отличающийся тем, что получение расплава осуществляют в печи с инертной атмосферой, рабочее пространство которой состоит из трех зон - зоны плавления, зоны легирования и зоны выдачи полученного расплава в кристолизаторы для вытяжки из них литой заготовки, в качестве легирующих используют элементы, имеющие гексагональную или тетрагональную кристаллические решетки, а формирование профиля провода осуществляют в два этапа - сначала получают методом волочения со степенью деформации 15-50% пруток, из которого затем прокаткой со степенью деформации 50-70% получают необходимый профиль провода.A method of producing contact wires, including obtaining a melt, alloying it, drawing a cast billet and forming the required wire profile from it by plastic deformation, characterized in that the melt is produced in an inert atmosphere furnace, the working space of which consists of three zones - a melting zone, alloying zones and zones for transferring the obtained melt to cristolizers for drawing cast billets out of them, elements having hexagonal or tetragonal cr crystal lattice, and the formation of wire profile is carried out in two phases - first, a method of drawing with a degree of deformation of the bars 15-50%, which is then rolled with a degree of deformation of 50-70% is obtained necessary wires profile.
