Description
Обычно примен емые покрыти электродов дл электропечей подвергаютс окислению, что приводит к повышенному расходу ЭоТектродов и большим просто м печей.Commonly used electrode coatings for electric furnaces are subject to oxidation, which leads to increased consumption of EOtelectrodes and more simply m furnaces.
По существуюшим способам дл запциты от окислени поверхности электродов их покрывают слоем керамической массы, котора при нагреве образует защитную оболочку из глинозема н кремнезема (авт. св. № 90171). При этом покрытие электродов керамической массы осуществл етс предпри тием, производ шим плавку.According to the existing methods for protection from the oxidation of the surface of the electrodes, they are coated with a layer of ceramic material, which, when heated, forms a protective sheath of alumina and silica (ed. St. 90171). In this case, the coating of the electrodes of the ceramic mass is carried out by the enterprise, which produces melting.
В отличие от известных способов в описываемом, с целью повышени работоспособности электродов, предлагаетс в качестве заш,итного сло примен ть ПJaмoтoгpaфитoвy o смесь, предохран юшую от сгорани .In contrast to the known methods in the described, in order to improve the efficiency of the electrodes, it is proposed to use a mixture of anti-combustion mixture as a protective layer.
Дл этого при изготовлении электродов на их поверхность впрессовываетс слой из графитоЕпамота: .механической графита и шамота , затворенной на каменноугольной смоле.To do this, in the manufacture of electrodes, a layer of graphite-emulsion is pressed onto their surface: mechanical graphite and chamotte, closed on coal tar.
Процесс обжига и графитизаци электродов осушествл ютс по обычной технологии производства графитированных электродов.The firing process and the graphitization of the electrodes are carried out according to the usual technology for the production of graphite electrodes.
На фиг. 1 схематичноизображено строение электрода в зажиме головкп электрододержател ; на фиг. 2 - то же, в рабочем пространстве печи.FIG. 1 schematically depicts the structure of the electrode in the clamping chuck of the electrode holder; in fig. 2 - the same, in the working space of the furnace.
Отформованный сырой электрод состоит из сердцевины / и графитошамота 2. С продвижение.м электрода в рабочее пространство печи углерод графитошамота 2 сгорает и на поверхности электрода образуетс инертна оболочка из шамота 3, котора предохран ет сердцевину / от интенсивного окислени . Таким образом, в рабочем пространстве печи графитированный электрод преобретает третий зашитный слой - шамот 3.The formed raw electrode consists of a core / and graphite chamfer 2. With the electrode advancing into the working space of the furnace, graphite chamfer 2 carbon burns and an inert shell of chamotte 3 forms on the electrode surface, which prevents the core from intense oxidation. Thus, in the working space of the furnace, the graphitized electrode acquires a third protective layer - chamotte 3.
