Claims (2)

1. Способ изготовления порошковой проволоки в металлической оболочке с фальцевым швом, включающий формирование из ленты U-образного желоба с вертикальными стенками различной высоты, заполнение желоба порошковым материалом, разравнивание и уплотнение порошка в желобе верхним приводным валком прокатной клети, формирование замкнутой трубчатой заготовки с фальцевым швом и ее редуцирование в трехвалковых калибрах с уменьшением диаметра заготовки в каждом из них до 8%, отличающийся тем, что ширина формируемого U-образного желоба равна диаметру замкнутой оболочки порошковой заготовки, при этом предварительно разравненный и уплотненный в желобе порошковый наполнитель дополнительно обжимается валками прокатной клети перед формированием замкнутой трубчатой оболочки.1. A method of manufacturing a flux-cored wire in a metal sheath with a seam seam, comprising forming a U-shaped gutter with vertical walls of various heights from the tape, filling the gutter with powder material, leveling and compacting the powder in the gutter with an upper drive roll of the rolling stand, forming a closed tubular blank with a seam seam and its reduction in three-roll calibers with a reduction in the diameter of the workpiece in each of them to 8%, characterized in that the width of the formed U-shaped groove is equal to the diameter ru of the closed shell of the powder billet, while the pre-leveled and compacted powder filler in the trough is additionally crimped by the rolls of the rolling stand before forming the closed tubular shell. 2. Способ по п.1, отличающийся тем, что дополнительное обжатие порошка в U-образном желобе осуществляют в прокатной клети гребнем верхнего валка, на котором выполнен овальный ручей радиусом, равным половине диаметра формируемой трубчатой заготовки.2. The method according to claim 1, characterized in that the additional compression of the powder in the U-shaped trough is carried out in the rolling stand by the crest of the upper roll, on which an oval stream is made with a radius equal to half the diameter of the formed tubular workpiece.
