Description
(54) СПОСОБ НЕПРЕРЬГОНОЙ РДЗЛИВКИ МЕТАЛЛОВ(54) METHOD OF CONTINUOUS METAL BONDING
tt
Изобретение относитс к области металлургии, конкретнее к непрерывной разливке металлов и сплавов.The invention relates to the field of metallurgy, and more specifically to the continuous casting of metals and alloys.
Известен способ непрерывной разливки металлов, вклгочаюгоий пропускание $ потока жидкого металла через жидкий охладитель .The known method of continuous casting of metals, including the transmission of a stream of liquid metal through a liquid cooler.
Однако при таком способе недосуаточна устойчивость, потока жидкого металла в окружающем жидком охладителе tO ограничивает скорость разливки, ухудшает качество заготовок и приводит к нарушению процесса разливки.However, with this method, lack of stability, the flow of liquid metal in the surrounding liquid cooler tO limits the casting speed, degrades the quality of the workpieces and leads to disruption of the casting process.
С целью повышени устойчивости по-|5 тока металла fi окружающем жидком охладителе и ускорени скорости,разлив ,ки на поток разливаемого металла воздействуют nepeMeHHiavj магнитным полем напр женностью 10 - 10 а/м, 20 вектор индукции которого параллелен оси потока и примен; ют жидкий охладитель , электропроводность которого ниже , чем электропроводность разливаемого металла.25In order to increase the stability of the metal current fi surrounding the liquid cooler and speed up the spill, the nepeMeHHiavj is affected by a magnetic field with a strength of 10 - 10 a / m, the induction vector of which is parallel to the flow axis and applied; liquid cooler, the electrical conductivity of which is lower than the electrical conductivity of the metal being cast.
В результате взаимодействи магнитного пол с наведенными им же в разливаемом металле возникают объемные иептростре 1ительние силы, повышающие устойчивость потока разливае- 30As a result of the interaction of the magnetic field with bulk induced by it in the cast metal, three-dimensional gravitational forces arise that increase the stability of the flow of the casting 30
мого метаЛпа в окружающем жидком охладителе . .MyMalPa in the surrounding liquid cooler. .
Воздействие магнитным полем напр женностью менее 10 а/м не окажет Зс1метного вли ни на устойчивость верхности потока металла, так как создаваемые им силы будут соответствовать силам, действукицим на границе жидкостей с различием в плотност х менее чем - I кг/м, что позволит вес .ти разливку только со скорост ми, соOTjeeTCTByribuiMH ламинарному движению потоков. Воздействие на поток разливаемого металла переменным магнитным полем напр женностью большей чем 10 а/м сделает необходимым отвод теплового lioTOKaплотностью не менее чем 10 Вт/м, что будет больше максимсшьного теплового потоку, который может быть отведен через окружгиощий жидкий охлгцхитель.An impact with a magnetic field strength of less than 10 a / m will not have a significant effect on the stability of the metal flow surface, since the forces created by it will correspond to the forces acting on the boundary of liquids with a difference in densities less than –1 kg / m, which will allow weight .ti casting only at speeds, according tojeeTCTByribuiMH to laminar flow. The impact on the flow of the metal being cast by an alternating magnetic field with a intensity greater than 10 a / m will necessitate a thermal lioTOK removal with a density of not less than 10 W / m, which will be greater than the maximum heat flux that can be diverted through the surrounding liquid cooler.
