In metallurgy and material science, scot deoxidising tubes Cb3 are specialised tubes or containers used to remove oxygen from a substance or a gas mixture. Deoxidation is a crucial process since oxygen can have a number of detrimental impacts on metallic materials, including corrosion, embrittlement, and porosity. Depending on the exact use, different materials can be used to create these items. Alumina, zirconia, and graphite are some typical materials. The material or gas mixture that needs to be deoxidized is normally fed through these scot deoxidising tubes Cb3, which are usually situated in a high-temperature furnace or chamber.
