Description
После этого размыкают электрическую цепь дорн-труба.After that, open the electrical circuit Dorn-pipe.
Тепло от трубы переходит к оребрению (дл интенсивпого отбора тепла примен ют обдув оребрени воздухом), температура трубы и ребер стремитс вырави тьс , труба остывает, происходит ее усадка, т. е. уменьшеиие ее диаметра .The heat from the pipe goes to the fins (for intensive heat extraction, air is applied to the fins), the temperature of the pipe and fins tends to flatten, the pipe cools, its shrinkage occurs, i.e. its diameter decreases.
В этот момеит начинают выт гивать дорн из трубы, чем и осуществл ют раздачу на величину усадки трубы, что достаточно дл плотного соединени ребер с трубой, а штанга при такой раздаче трубы работает только на раст л ение .At this moment, the mandrel begins to be pulled out of the pipe, and this distributes by the amount of shrinkage of the pipe, which is enough to tightly connect the ribs with the pipe, and the bar with this distribution of the pipe works only for extension.
