Description
Известны высокочастотные вакуумные печи дл плавки металла, у которых первична обмотка трансформатора расположена вне вакуумной камеры, а индуктор и вторична обмотка трансформатора, электрически св занные между собой, расположены в вакуумном пространстве . Предложенна печь отличаетс от известных тем, что у нее индуктор и вторична обмотка трансформатора выполнены в виде двух индуктивно св занных коаксиальных катушек, охлаждаемых водой. Така конструкци индуктора и вторичной обмотки трансформатора обеспечивает повышение коэффициента индуктивной св зи печи.High frequency vacuum furnaces for melting metal are known, in which the primary winding of the transformer is located outside the vacuum chamber, and the inductor and the secondary winding of the transformer, electrically interconnected, are located in vacuum space. The proposed furnace differs from the known ones in that the inductor and the secondary winding of the transformer are made in the form of two inductively connected coaxial coils cooled by water. This design of the inductor and the secondary winding of the transformer provides an increase in the inductive coupling coefficient of the furnace.
На чертеже изображена печь с частичным разрезом.The drawing shows a furnace with a partial cut.
Вакуумна камера / выполнена в виде цилиндра из изол ционного материала (например, кварца) с двум металлическими водоохлаждаемыми крышками 2. Цилиндр служит изол тором дл двух концентрических катушек, представл ющих собой воздушный трансформатор: наружна катушка 3 вл етс первичной обмоткой трансформатора, а внутренн катушка 4, наход ща с в вакуумной камере, вл етс вторичной обмоткой. Эта обмотка подключена к индуктору 5, выполненному в виде катушки, коаксиально расположенной внутри вторичной обмотки. Тигель 6 с металлом помещен в индукторе.The vacuum chamber / is made in the form of a cylinder of insulating material (for example, quartz) with two metal water-cooled lids 2. The cylinder serves as an insulator for two concentric coils, which are an air transformer: the outer coil 3 is the primary winding of the transformer, and the inner coil 4, being in a vacuum chamber, is a secondary winding. This winding is connected to the inductor 5, made in the form of a coil, coaxially located inside the secondary winding. Crucible 6 with metal is placed in the inductor.
Толщина стенок вакузмной камеры выбираетс такой, при которой обеспечиваетс высокий коэффициент св зи между обмотками трансформатора . Величина св З:И в системе индуктор-металл определ етс в предложенной печк только толщиной стенок тигл и поэтому вл етс максимально возможной дл данной системы.The wall thickness of the vacuum chamber is chosen such that it provides a high coupling coefficient between the transformer windings. The magnitude of the bond G: And in the system, the inductor-metal is determined in the proposed furnace only by the thickness of the crucible walls and therefore is the maximum possible for this system.
