Abstract
1. СПОСОБ ПОЛУЧЕНИЯ ОТЛИВОК, в том числе непрерывных слитков произвольного сечения с использованием электромагнитного поля для удержания и обжатия расплава, о т л и ч а rant и и с я тем,что, с целью бесконтактного формообразования отливки, разлагаемый металл или сплав в жидком виде подают в электромагнитное поле, удерживающее его в заданных контурах отливки, и одновременно с электромагнитным воздействием на разливаемый материал осуществляют принудительное его охлаждение, обеспечивающее кристаллизацию, по крайней мере, оболочки,способной вьщержать давление жидкой фазы.2.Способ по п. 1, отличающийся тем,что, с целью компенсации статического давления в распла-i ве, создают неравномерное электромагнитное поле путем выбора формы, линейных размеров шага и числа витков индуктора, а также конструкции внешних магнитопроводов.3.Способ по пп. 1 и 2, о т л и- чающийся тем, что,с целью изменения давления в затвердевающем металле, на него воздействуют бегущим магнитным полем.4.Способ по п. 1, отличающийся тем,что, с целью получения полых отливок, расплав заливают в электромагнитное поле в пространство между двумя концентрическими индукторами.5.Способ по п. 1, отличающийся тем,что,с целью формирования отдельных частей внешнего контура отливки, например днища слитков, используют огнеупорные поверхности.(Лi^РО^Од qD1. METHOD FOR GETTING CASTINGS, including continuous ingots of arbitrary cross section using an electromagnetic field to hold and compress the melt, which is tant and rant, and with the fact that, for the purpose of contactless shaping of the casting, a decomposable metal or alloy in a liquid the form is fed into an electromagnetic field that holds it in the specified casting contours, and simultaneously with the electromagnetic impact on the material being poured, it is forced to cool, providing crystallization of at least the shell capable of to press the pressure of the liquid phase. 2. Method according to claim 1, characterized in that, in order to compensate for the static pressure in the melt, they create an uneven electromagnetic field by selecting the shape, linear dimensions of the step and the number of turns of the inductor, as well as the design of external magnetic circuits .3. Method according to paragraphs. 1 and 2, because of the fact that, in order to change the pressure in the hardening metal, it is exposed to a traveling magnetic field. 4. The method according to claim 1, characterized in that, in order to obtain hollow castings, the melt is poured in the electromagnetic field into the space between two concentric inductors. The method according to claim 1, characterized in that refractory surfaces are used to form separate parts of the outer contour of the casting, for example, the bottom of ingots. (Li ^ PO ^ Q q
