Description

(54) ФУРМА ДЛЯ ПРОДУВКИ МЕТАЛЛА(54) METAL BLOWING MILL

Проникновении кислорода в трубопровод природного газа (перепад давлений на обратном клапане 7 уменьшаетс  и он закрываетс .The penetration of oxygen into the natural gas pipeline (the pressure drop across the check valve 7 decreases and it closes.

В случае необходимости использовать защитный газ с удалением его из металла можно Применить несколько защитных сред, например , можно использовать азот, а в последней трети продувки аргон, способствующий удалению азота из металла.If it is necessary to use shielding gas and remove it from the metal, several protective media can be used, for example, nitrogen can be used, and in the last third of the purge argon can be used to remove nitrogen from the metal.
