Claims (2)

1. Способ изготовления порошковой проволоки для внепечной обработки стали, включающий формирование из стальной ленты U-образного желоба, заполнение желоба порошком наполнителя, создание трубчатого профиля с зет-образным замковым соединением и редуцирование полученной трубчатой заготовки, отличающийся тем, что U-образный желоб заготовки формуют без отбортовки краев желоба, при этом засыпанный порошок уплотняют в желобе приводным верхним валком прокатной клети перед созданием замкнутого трубчатого профиля, а редуцирование трубчатой заготовки осуществляют последовательным протягиванием через два круглых трехвалковых калибра с уменьшением диаметра заготовки в каждом из них до 8%.1. A method of manufacturing a flux-cored wire for out-of-furnace steel processing, comprising forming a U-shaped gutter from a steel strip, filling the gutter with filler powder, creating a tubular profile with a z-shaped locking joint and reducing the resulting tubular workpiece, characterized in that the U-shaped workpiece groove formed without flanging the edges of the gutter, while the powdered powder is compacted in the gutter with a drive upper roll of the rolling stand before creating a closed tubular profile, and reduction of the tubular otovki performed through sequential pulling the two circular three-roll caliber diameter reduction blank each including up to 8%. 2. Технологическая линия для изготовления порошковой проволоки для внепечной обработки стали, содержащая разматыватель рулонов, профилегибочный стан с горизонтальными и вертикальными неприводными клетями и дозатором для подачи порошка в заготовку, редукционный блок для получения окончательного размера проволоки, волочильный барабан и моталку для смотки проволоки в бунты, отличающаяся тем, что линия включает прокатную клеть с приводными валками, расположенную за дозатором, устройство для закрытия замка в трубчатом профиле, смонтированное за вертикальной формующей клетью, а также сдвоенную трехвалковую клеть с неприводными валками, установленную за последней формирующей клетью. 2. A technological line for the production of flux-cored wire for out-of-furnace steel processing, comprising a roll unwinder, a roll forming mill with horizontal and vertical non-driven stands and a batcher for feeding powder into the workpiece, a reduction unit for obtaining the final wire size, a drawing drum and a coiler for winding wire into riots characterized in that the line includes a rolling stand with drive rolls located behind the dispenser, a device for closing the lock in a tubular profile, mounted located behind the vertical forming stand, as well as a double three-roll stand with non-driven rolls, installed behind the last forming stand.
