Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

Changes in mill design using screw rolling in calibrated rolls were proposed and tested. Solid-phase welding in upgraded vacuum rolling mill was used to produce extended bimetal transition pieces with a helical texture that allows making sound solid-phase joints of more than 200 mm length of low-carbon steel and 08Kh18N10T steel. Investigation results were used to develop the technology of screw rolling in calibrated rolls. 12 Ref., 8 Figures.
Keywords: vacuum screw rolling, extended tubular element of the transition piece, bimetal composites, upgrading
