Abstract

Способ получения порошковой проволоки с повышенной плотностью порошкового наполнителя, включающий непрерывное формирование из металлической ленты U-образного профиля с одновременным заполнением его порошковым наполнителем с разравниванием и предуплотнением, формирование замкнутого трубчатого профиля оболочки с фальцевым замком и редуцирование, отличающийся тем, что предуплотнение и разравнивание порошка ведут на устройстве вибрационного типа, а редуцирование замкнутого трубчатого профиля с фальцевым замком производят в сдвоенной трехроликовой фильере, причем в первой группе роликов осуществляют образование трех глубоких гофров, обеспечивающих уменьшение поперечного сечения профиля до 20%, при этом один из гофров располагают в непосредственной близости к фальцевому замку, а во второй группе роликов, сдвинутых на 60° по оси формовки относительно первой, осуществляют калибрование профиля с одновременным поджатием трех образованных гофров с возможностью уменьшения площади поперечного сечения профиля до 25%.A method of producing a flux-cored wire with an increased density of the powder filler, including the continuous formation of a U-shaped profile from a metal tape with its simultaneous filling with a powder filler with leveling and pre-sealing, forming a closed tubular sheath profile with a rebate lock and reduction, characterized in that the powder sealing and leveling lead on the device of the vibrational type, and the reduction of the closed tubular profile with a rebate lock is performed in double a three-roller die, and in the first group of rollers, three deep corrugations are formed, which reduce the cross-section of the profile to 20%, while one of the corrugations is located in close proximity to the fold lock, and in the second group of rollers shifted 60 ° along the molding axis relative to the first, carry out the calibration of the profile with simultaneous preloading of three formed corrugations with the possibility of reducing the cross-sectional area of the profile to 25%.
