    Bright Annealing Tube Production Control:

    • Smelting raw materials must have good control, the level required to meet the microstructure times better level.
    • Cold rolling volume control and reasonable within the organization in order to avoid defects.
    • Mold control, to ensure the inner and outer surface roughness R a ≤ 0.3μm.
    • Bright annealing control to ensure reasonable mechanical properties and surface brightness, and eliminate the pass mechanical polishing (MP), to ensure the smoothness of the inner surface under microscopic state, to avoid transmission fluid residues.
    • Cleaning the control surfaces should have the products delivered better cleanliness and cleanliness, with metallic colors, no oil adhesion, oxide adhesion.
    • Single hats loss prevention bagging, overall braid or wooden packaging.

    The material of the stainless steel round bar is from Jiuli and Baosteel China, we control the quality from the very start. We polished three times to make sure the surface is perfect bright and smooth, and without any deficiency in quality.

    The Bright Annealing Tube System can either be placed standalone or in-line with surface reduction equipment to create a total in-line process. Innovative design allows for easy changeover from product to product, and each system is equipped with automatic power control and precision temperature control through recipe parameters.

    • Designed for ease of operation and maintenance
    • Automatic speed sensor controls power proportionate to line speed
    • Recipe storage and retrieval
    • Integrated temperature sensing
    • High wear ceramic tube guides
    • Integrated pumping system
    • Solid state inverters, operating in both medium and high frequencies

    Bright annealing (BA) refers to stainless steel material is heated in closed furnace in reducing atmosphere of inert gases, common Hydrogen gas, after fast annealing, rapid cooling, stainless steel has a protective layer on the outer surface, no reflect in open air environment, this layer can resist corrosion attack. In general, material surface is more smooth and brighter.

    Bright Annealing Tube

    Tube is processed in bright annealing finish, in this process, some factors are important for quality tube, if bright annealing process is not proper, that will result in crack, then may corrosion.

    Before Bright Annealing

    The surface of the tube must be clean, no other foreign matter, any matter left on the tubing surface can cause damage during the process.

    Inserted Gas

    Annealing atmosphere should be free from Oxygen, isolating material, creating a vacuum condition. Inserted gas, common dry hydrogen or argon, can obtain bright result.

    Annealing Temperature

    Annealing temperature should be noticed depending on different stainless grades, commonly Austenitic steels annealing temperature is at least 1040 degree, soak time is not important. high temperature must be required to have brighter appearance. Heating is done as fast as possible, slow heat results in oxidation.

    Some Ferritic stainless steels require lower annealing temperature, such as TP439, cannot be effectively bright annealed, Water quenching will cause scale formation.
