Description
ществлена следующим образом. Между индуктором и вогнутой поверхностью каждой секции оболочки размещаетс на всю ее длину тонкий лист немагнитной стали, который привариваетс к выпуклост м секции оболочки . При этом полость между вогнутой поверхностью секции оболочки и этим листом делают герметичной и подсоедин ют ее к подвод щим и отвод щим охлаждающую среду системам .It is as follows. Between the inductor and the concave surface of each shell section, a thin sheet of nonmagnetic steel is placed over its entire length, which is welded to the convexity of the shell section. In this case, the cavity between the concave surface of the shell section and this sheet is sealed and connected to the inlet and outlet cooling systems.
При эксплуатации печи около охлаждаемой оболочки и особенно в более удаленных от центра участках тигл посто нно сохран етс слой сыпучего материала, компенсирующего деформации спеченной части тигл при его нагреве и охлаждении. В этой компенсации деформаций участвует и оболочка путем упругих деформаций ее вогнутых участков. Следовательно , получаютс услови посто нной более надежной компенсации термических деформаций спеченной части тигл , что приводит к удлинению срока службы тигл и вместе с тем обеспечивает жесткую св зь тигл с индуктором.During operation of the furnace near the cooled shell, and especially in areas more distant from the center of the crucibles, a layer of bulk material is constantly maintained, compensating for the deformation of the sintered portion of the crucible during its heating and cooling. The shell is also involved in this compensation of deformations by elastic deformations of its concave portions. Consequently, the conditions for a more reliable compensation of thermal deformations of the sintered part of the crucibles are obtained, which leads to a prolongation of the service life of the crucibles and at the same time provides a rigid connection between the crucibles and the inductor.
В описываемой печи стойкость футеровки больще вследствие более низкой средней температуры нагрева тигл . Кроме того, в ней исключаетс попадание жидкого металла на индуктор, так как, в случае проникновени металла до оболочки и даже ее проплавлени , что мало веро тно при условии наход щегос перед ней нерастрескиваюнхегос сыпучего сло и интепсивпого охлаждени оболочки, металл ггопадает в полости между индуктором и оболочкой и беспреп тственно падает. Оболочка в описываемой печи вл етс экраном, который может быть использован в известных схемах сигнализации о «проедании тигл , а 1Ю температуре отход щей охлаждающей среды , например, можно косвенно контролировать состо ние футеровки.In this furnace, the lining resistance is longer due to the lower average heating temperature of the crucibles. In addition, it eliminates the ingress of liquid metal on the inductor, since, in the case of penetration of the metal to the shell and even its melting, which is unlikely under the condition of the non-cracked bulk layer and the cooling of the shell in front of it, the metal drops in the cavity between the inductor and the shell and falls freely. The shell in the furnace being described is a screen that can be used in the well-known crucible eating signaling schemes, and the 1o temperature of the exhaust cooling medium, for example, can indirectly monitor the condition of the lining.
