Изобретение относитс к обработке металлов, а именно к устройствам дл непрерывного лить в форму с движущимис стенками.The invention relates to the processing of metals, namely, devices for continuous casting into molds with moving walls.
Известны роторные кристаллизаторы дл непрерывного лить , в которых форма дл заливки металла образована -желобом на внешней поверхности литейного кoлeta (ротора), вращающегос на горизонтальной оси, и замкнутым кольцом из ленты, охватывающим желоб .Rotary crystallizers for continuous casting are known, in which the mold for pouring metal is formed by a groove on the outer surface of a casting collar (rotor) rotating on a horizontal axis and a closed ring of tape surrounding the chute.
Недостатком известного устройства вл етс посто нство площади сечени литейной формы по ходу кристаллизации отливки. Уровень жидкого металла при заливке расположен обычно выше горизонтальной оси ротора на На сравнительно малом рассто нии от уровн заливки по ходу вращени образуетс внешн корка затвердевшего металла ,происходит ее усадка и возникает воздушный зазор между отливкой и формой. Интенсивность охлаждени резко умень7A disadvantage of the known device is the constancy of the cross-sectional area of the casting mold during the crystallization of the casting. The level of the liquid metal during casting is usually located above the horizontal axis of the rotor. At a relatively small distance from the fill level, an outer crust of the hardened metal is formed during rotation, it shrinks and an air gap occurs between the casting and the mold. Cooling intensity drastically reduced.
шаетс , и станов тс возможными локальные проплавлени тонкой корки жидким металлом сердцевины отливки-выплески , почти мгновенно затвердевающие, но способные служить очагами образовани трещин при разгибании отливки на выходе из кристаллизатора. Ниже горизонтальной оси ротора отливка за счет своего веса прижимаетс к ленте, и затвердевание с внешней стороны идет быстрее, а расплавленна сердцевина смещаетс к внутренней донной части сечени отливки, и по завершении кристаллизации в этой части наблюдаетс усадочна рыхлота, ослабл ю15 ща сечение именно Там, где действуют раст гивающие напр жени от изгиба при выводе отливки из ротора.The local penetrations of the thin crust with the liquid metal of the casting-splash cores, which almost instantaneously harden, but can serve as foci of cracking when the casting is extended at the outlet of the crystallizer, become possible. Below the horizontal axis of the rotor, due to its weight, the casting is pressed to the belt, and solidification from the outer side proceeds faster, and the molten core shifts to the inner bottom part of the casting section, and upon completion of the crystallization, shrinkage is observed in this part, weakening the cross section there, where tensile stresses from bending act when casting out of the rotor.
