Description
тел и стенки изложницы, обращенной к слитку.bodies and walls of the mold, facing the ingot.
Изложница работает следующим образом .The ingest works as follows.
По мере наполнени изложницы металлом его тепло передаетс стенкам изложницы . Часть этого тепла поглощаетс стенками изложницы, а друга часть материалом-наполнителем . Материал-наполнитель значительно быстрее передает тепло вверх, которое обогревает стенки изложницы в верхних менее прогретых ее сло х. При этом количество тепла, передаваемое стенкам полости, обращенным во внутрь изложницы , значительно больше тепла, передаваемого стенкам полости, обращенным к наружной поверхности изложницы вследствие отличи их площадей. По мере наполнени изложницы металлом градиент температуры между ними постепенно снижаетс . Это позвол ет уменьшить интенсивность теплоотдачи от слитка к изложнице и содержать металл слитка в расплавленном состо нии более длительное врем . Создаютс более благопри тные услови дл питани тела слитка металлом прибыльной части.As the mold is filled with metal, its heat is transferred to the walls of the mold. Some of this heat is absorbed by the walls of the mold, and the other part is absorbed by the filler material. The filler material transfers heat up much faster, which heats the walls of the mold in the upper less heated layers. At the same time, the amount of heat transferred to the cavity walls, which are turned inside the mold, is much greater than the heat transmitted to the cavity walls, which are turned to the outer surface of the mold, due to the difference in their areas. As the mold is filled with metal, the temperature gradient between them gradually decreases. This makes it possible to reduce the heat transfer rate from the ingot to the mold and to keep the ingot metal in the molten state for a longer time. More favorable conditions are created for feeding the ingot body with metal from the profitable part.
Использование предлагаемых изложницUse of the proposed molds
позвол ет снизить расход металла на первом переделе примерно на 2%, улучшить качество проката и поковок, сократить расход изложниц на 3-5 кг на тонну стали. allows to reduce the consumption of metal in the first stage by about 2%, to improve the quality of rolled products and forgings, to reduce the consumption of molds by 3-5 kg per ton of steel.
