Description
1-1зобретение относитс к способам получени заготовок ИЗ жидкого металла на установках непр ерывной разливки. Известен способ получени заготовок на установках непрерывной разливки, заключающийс в том, что металл подают -в радиальный кристаллизатор и выт гивают заготовку вверх, при этом давление в жидкой сердцевине регулируют электромагнитными насосами. По предлагаемому способу дл повышени скорости разливки металла в начале периода остановки заготовки увеличивают давление в жидкой сердцевине, а перед .выт гиванием заготовки снижают давление. На чертеже изображена установка непрерывной разливки металла дл получени заготовок по предлагаемому способу. Жидкий металл из ковша / через сифонную систему 2 подают снизу в радиальный кристаллизатор 3. Перед началом разливки в кристаллизатор ввод т затравку 4, соединенную с выт гивающим устройством 5. Заготовку 6 после образовани корочки затвердевшего металла выт гивают, ввод т в зону действи электромагнитных насосов / и делают остановку . В начале периода остановки электромагнитными насосами увеличивают давление в жидкой сердцевине и прижимают корочку металла к стенкам кристаллизатора дл интенсивного отвода тепла. В конце периода остановки сниж:ают давление в жидкой сердцевине, чтобы исключить возможный разрыв корочки после отхода ее от стенок кристаллизатора при усадке. Затем заготовку выт гивают на определенную высоту п повтор ют операции. Предмет изобретени Способ получени заготовок на установках непрерывной разливки металла с радиальным кристаллизатором, при котором осуществл ют периодическое выт гивание заготовки вверх и регулирование давлени в жидкой сердцевине, например, с помощью электромагнитных насосов , отличающийс тем, что, с целью повышени скорости разливки, в начале периода остановки заготовки увеличивают давление в жидкой сердцевине, а перед выт гиванием заготов ки снилсают давление.1-1, the invention relates to methods for producing blanks from liquid metal in continuous casting plants. A known method for producing blanks in continuous casting plants consists in that the metal is supplied to the radial mold and the workpiece is pulled upwards, while the pressure in the liquid core is controlled by electromagnetic pumps. According to the proposed method, in order to increase the speed of metal casting at the beginning of the blanking period, the pressure in the liquid core is increased, and the pressure is reduced before the extraction of the workpiece. The drawing shows the installation of continuous casting of metal to obtain blanks for the proposed method. Liquid metal from the ladle / through the siphon system 2 is fed from below into the radial mold 3. Before starting casting, a seed 4 is introduced into the mold, connected to a pulling device 5. The workpiece 6 is drained after the formation of a hardened metal crust / and make a stop. At the beginning of the stopping period, electromagnetic pumps increase the pressure in the liquid core and press a metal crust against the walls of the mold for intensive heat removal. At the end of the stopping period, the pressure decreases: the pressure in the liquid core in order to exclude a possible crust rupture after its separation from the walls of the crystallizer during shrinkage. Then, the workpiece is stretched to a certain height n and the operations are repeated. The subject of the invention. A method for producing blanks in continuous casting plants of metal with a radial crystallizer, in which the billet is periodically stretched upwards and pressure is controlled in the liquid core, for example, by means of electromagnetic pumps, characterized in that, in order to increase the casting speed, the stopping time of the workpiece increases the pressure in the liquid core, and before stretching the workpiece, the pressure is released.
