Description

Изобретение относитс  к производству бесшовных гор чекатаных труб из стали и сплавов , а именно к технологии удалени  окалины с поверхности гильз-труб в гор чем состо нии и может быть применено на любой трубопрокатной установке, имеющей в своем составе прошивной стан или пресс.The invention relates to the production of seamless hot-rolled pipes from steel and alloys, namely, to the technology of removing scale from the surface of the liner pipes in a hot condition and can be applied to any pipe-rolling installation having a piercing mill or a press.

Известны способы очистки в потоке трубопрокатных установок внутренней поверхности труб-гильз, нагретых до 1200-1300°С от окалины и других инородных тел продувкой их сжатым воздухом или воздушно-вод ной смесью. Однако при очистке этим способом происходит интенсивное окисление металла внутренней поверхности гильзы-трубы, а при очистке воздушно-вод ной смесью - ее значительное охлаждение.Methods are known for cleaning the pipe-rolling installations in the flow of the inner surface of pipe-sleeves heated to 1200-1300 ° С from scale and other foreign bodies by blowing them with compressed air or an air-water mixture. However, when cleaning by this method, intense oxidation of the metal of the inner surface of the tube-tube occurs, and during cleaning with an air-water mixture, its considerable cooling.

Предлагаемый способ отличаетс  тем, что их продувку осуществл ют газообразным веш ,еством, химически нейтральным по отношению к металлу гильзы-трубы, имеюш,ему 1200-1300°С, например, сухим вод ным паром , что обеспечивает качественную очистку внутренней поверхности гильзы трубы, исключа  при этом ее окисление и образование других дефектов.The proposed method is characterized in that they are purged with gaseous suspension, chemically neutral with respect to the metal of the sleeve-pipe, having 1200-1300 ° C, for example, with dry steam, which ensures high-quality cleaning of the inner surface of the sleeve of the pipe, excluding its oxidation and the formation of other defects.

Слиток или заготовку прошивают в гильзутрубу , которую затем непосредственно в потоке трубопрокатной установки продувают сухим вод ным паром или другим газообразным вешеством, не вызывающим окислени  гор чего металла. В результате продувки с внутренней поверхности гильзы-трубы удал етс  окалина и другие инородные тела. Очищенную гильзу-трубу передают дл  дальнейших операпий на следующие агрегаты трубопрокатной установки.The ingot or billet is stitched into the sleeve, which is then directly in the stream of the pipe-rolling installation is blown with dry water vapor or other gaseous substance that does not cause oxidation of the hot metal. As a result of the blow, scale and other foreign bodies are removed from the inner surface of the sleeve-tube. The cleaned sleeve tube is transferred for further operations to the following units of the pipe rolling installation.
