Изобретение относитс к металлургии и может быть использовано при термической обработке проволоки.The invention relates to metallurgy and can be used in the heat treatment of wire.
Известен способ пуска установки электроконтактного нагрева проволоки, включающнй операцию прот жки проволоки над установкой , заправки ее на т нущий барабан и заправки при включенном напр жении нагрева под подгружатели заземленного и потенниального контактов. Однако такой способ пуска сопровождаетс часто перегревом и обрывом проволоки.A known method of starting the installation of electrical contact heating of the wire, including the operation of drawing the wire over the installation, charging it to a pull drum and charging it with the heating voltage turned on, under the loaders of grounded and potential contacts. However, this method of starting is often accompanied by overheating and breakage of the wire.
Цель изобретени - сокращение обрывов нроволокп при пуске многониточной установки путем увеличени длины проволоки, подключаемой па рабочее напр жение, что ведет к снижениЕо затрат труда, экономии металла и новышению производительности.The purpose of the invention is to reduce nolococ breaks during the start-up of a multi-line installation by increasing the length of the wire connected to the operating voltage, which leads to a reduction in labor costs, metal savings and increased productivity.
Поставленна цель достигаетс тем, что проволоку заправл ют сначала нод последНИИ по ходу ногружатель заземленного контакта , далее под погружатель потенциального контакта и затем под первый погружатель заземленного контакта.The goal is achieved by first threading the node of the last node along the grounding terminal, then under the potential contact plunger, and then under the first ground contact plunger.
На чертеже показана схема установки и положени проволоки в моменты операций пуска.The drawing shows an installation diagram and a wire position at the time of the starting operation.
Двпжущуюс проволоку 1, прот нутую над установкой, снимают с крюка 2 и заправл ют под последний по ходу движени проволоки погружатель 3 заземленного контакта-патентировочной ванны 4, а потом снимают с крюка 5 и заправл ют под погружатель потенциального контакта - ванны 6. Начина с этого момента, участок проволоки, равны) длине (), оказываетс включенным на рабочее напр жение. После окончани переходного процесса проволоку заправл ют под первый погружатель 7 заземленного контакта. При этом участок нагрева уменьшают до рабочего, равного длине ().Duplex wire 1 stretched over the unit is removed from hook 2 and tucked under the latter in the course of wire movement by the immersion submersible 3 of the grounded contact of the patented bath 4, and then removed from the hook 5 and charged under the potential contact immersion bath 6. At this moment, the wire segment, equal to the length (), is turned on for the operating voltage. After the end of the transition process, the wire is threaded under the first immersion 7 of the ground terminal. In this case, the heating section is reduced to the working equal to the length ().
Услови пуска установки данным способом значительно улучшаютс , так как длину участка проволокп, подключенного при пуске на рабочее напр жение, уменьшают до номинальной в два приема, благодар чему перегрев проволоки снижают до допустимых пределов, и иуск установки проходит без обрывов.The conditions for starting the installation in this way are significantly improved, since the length of the wire section connected during the start-up of the operating voltage is reduced to the nominal in two steps, whereby the overheating of the wire is reduced to permissible limits, and the installation is started without breaks.
