Glass melting component

FIELD: glass melting. SUBSTANCE: invention relates to a method for producing a glass melting component, as well as the glass melting component. A method for producing a glass melting component that consists of a refractory metal in which the surface area of the glass melting component is compacted, at least partially, by applying a local compressive force. As a result, its porosity decreases in comparison with the volume part, which is located below the surface zone and has a residual porosity. After compacting the surface area, the glass melting component, or at least the surface area of the glass melting component, is heat-treated at a temperature higher than the recrystallization temperature of the refractory metal, so that grain growth is caused in the surface area. EFFECT: technical result is the provision of a method for producing a component for glass melting, which consists of a refractory metal with high resistance to glass melts. 14 cl, 5 tbl, 10 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 743 722 C2 (51) МПК C03B 5/43 (2006.01) F27B 14/10 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C03B 5/43 (2020.02); F27B 14/10 (2020.02) (21)(22) Заявка: 2018135612, 23.03.2017 (24) Дата начала отсчета срока действия патента: Дата регистрации: 24.02.2021 R U 23.03.2017 (72) Автор(ы): ТРАКСЛЕР Ханнес (AT), МАРК Михель (AT), ШИФТНЕР Роберт (AT), КНАБЛЬ Вольфрам (AT) (73) Патентообладатель(и): ПЛАНЗЕЕ ЗЕ (AT) 25.03.2016 AT GM 64/2016 (43) Дата публикации заявки: 27.04.2020 Бюл. № 12 (45) Опубликовано: 24.02.2021 Бюл. № 6 (56) Список документов, цитированных в отчете о поиске: WO 2011066126 A1, 03.06.2011.
