Description
II
Изобретепне относитс к металлургии и может использоватьс при получении высокоKfitecTiieniioii стали с низким содержанием вредпых примесей, неметаллических включепий , а также газов.The invention relates to metallurgy and can be used in the preparation of high KfitecTiieniioii steel with a low content of harmful impurities, non-metallic inclusions, as well as gases.
Известен способ разлпвки стали с пропусканием металла в процессе разливки через огпеунорный фильтр.There is a method of razvpvki steel with the transmission of metal in the process of casting through ogneunorny filter.
Однако при его применении удаление мелких включений незначительно. Контактный слой стали у поверхности фильтра охлаждаетс , так как температура фильтра существенпо ниже температуры жидкой стали, и вл етс преп тствием дл адгезии поверхностью фильтра неметаллических включений, особенно мелких, обладаюи1:их педостаточиой энергией .However, when applied, the removal of small inclusions is insignificant. The contact layer of steel at the surface of the filter is cooled, since the temperature of the filter is substantially lower than the temperature of the liquid steel, and is an obstacle to the adhesion of the surface of the filter to non-metallic inclusions, especially small ones, possessing 1: their energy efficiency.
Целью изобретени вл етс увеличение степени очистки металла.The aim of the invention is to increase the degree of metal purification.
Дл этого по описываемому способу фильтр перед заливкой стали нагревают до температуры 1200-1400°С и поддерживают ее в течение всего процесса фильтрации.To do this, according to the described method, the filter is heated to a temperature of 1200-1400 ° C before pouring the steel and maintain it during the entire filtration process.
Предлагаемый способ, кроме того, предусматривает осуществление фильтрации стали под вакуумом и в,атмосфере инертного газа.The proposed method, in addition, provides for the implementation of the filtration of steel under vacuum and in the atmosphere of inert gas.
а также в оегун1.ем магнитном поле, направленном вдоль нотока металла.and also in ogun1.em magnetic field directed along the metal notoka.
Предлагаемый способ позвол ет удал1Г1ь из сталп крупные (более 100 мкм) и средние неметаллические- включени и повыспть пластические свойства (относительное сужение и ударную в зкость) на 15-20%, что не обеснечипаетс фнльтрац 1сй без подогрева до высоких температур.The proposed method allows the removal of large (more than 100 microns) and medium nonmetallic inclusions and increases the plastic properties (relative narrowing and impact strength) by 15–20%, which does not disintegrate into high temperatures.
