Description
Предметом изобретени вл етс способ защиты электролизеров дл борировани стальных деталей от разъедани расплавленной бурой.The subject of the invention is a method of protecting electrolyzers for boring steel parts from being eroded by a molten borax.
В известном способе защиту внутренней поверхности от воздействи расплавленной буры обеспечивают путем охлаждени наружной поверхности ванны проточной водой, что приводит к большим потер м тепла через стенку электролизера.In the known method, the protection of the inner surface from the impact of the molten borax is ensured by cooling the outer surface of the bath with running water, which leads to large heat losses through the cell wall.
Предлагаемый способ катодной защиты позвол ет устранить указанный недостаток путем соединени металлического корпуса ванны с отрицательным полюсом источника тока . Борируемые издели соедин ют через корпус BaiHHbi с отрицательным полюсом источника тока контактно. Дл этого электролизер изготовл ют в виде сборника расплавленного электролита и группы ванн, соединенных по принципу сообщаюп1ихс сосудов и приспособленных дл установки изделий.The proposed cathodic protection method eliminates this drawback by connecting the metal body of the bath with the negative pole of the current source. The products being bounded are connected through the BaiHHbi case to the negative pole of the current source with a contact. For this, the electrolyzer is manufactured in the form of a collection of molten electrolyte and a group of baths, connected according to the principle of communicating vessels and adapted for the installation of products.
На приведенной схеме такого устройства сборник /, где происходит расплавление электролита 2, соединен по принципу сообщающихс сосудов с группой отдельных ванн 3, За, 36 и т. д., в которые введены самосто тельные аноды 4, 4а, 46 и т. д.In the diagram of such a device, a collector /, where electrolyte 2 is melted, is connected according to the principle of communicating vessels with a group of individual baths 3, 3a, 36, etc., into which self-contained anodes 4, 4a, 46, etc., are introduced.
Издели 5, подлежащие борированию установлены так, что наход тс в контакте с корпусами ванн 3, За, 36 и т. д. Последние присоединены к отрицательному полюсу источника тока 6. Дл устранени разъедани сборника 1 расплавленной бурой 2 в электролит введен дополнительный анод 7 со значительно больщим сопротивлением в цепи. Дл регулировани уровн электролита сборник герметически закрыт заглушкой 8 с сальником 5, который служит дл ввода дополнительного анода 7, и соединен штуцером 10 с компрессорно-вакуумной устаповкой 11 через кран 12.Products 5 that are to be borated are installed so that they are in contact with bath bodies 3, 3A, 36, and so on. The latter are connected to the negative pole of current source 6. To eliminate corroding of collection 1 of molten brown 2, additional anode 7 is introduced into the electrolyte. Significantly greater resistance in the circuit. To regulate the electrolyte level, the collector is hermetically sealed with a plug 8 with an epiploon 5, which serves to introduce an additional anode 7, and is connected by a fitting 10 to a compressor-vacuum unit 11 through a valve 12.
Нагрев электролизера производитс в печах сопротивлени , газовых печах или токами высокой частоты. Дл предохранени наружных поверхностей сборника и ванн от окислени последние можно защитить алитированнем или обмазкой, а также созданием нейтральной газовой среды.The electrolysis cell is heated in resistance furnaces, gas furnaces or high frequency currents. To protect the exterior surfaces of the collector and the baths from oxidation, the latter can be protected by aluminizing or coating, as well as by creating a neutral gas environment.
