Annealed Black Wire Is A Kind Of Black Steel Wire That Has Been Annealed At High Temperatures. In The Manufacturing Process, The Steel Wire Goes Through Multiple Processes Such As Drawing, Pickling, Cold Drawing, Annealing, Etc., And Finally Forms A Black Steel Wire Product.
The Annealed Black Silk Is Characterized By A Smooth Surface, No Obvious Rust Spots And Oxide Layers, And Has High Strength And Toughness. Due To The Annealing Treatment, The Grains Of The Steel Wire Are Rearranged And Crystallized, Which Improves The Performance Of The Steel Wire.
Annealed Black Wire Is Widely Used In Construction, Furniture, Machinery Manufacturing, Electrical Appliances Manufacturing, And Other Fields, Such As Making Grids, Sieves, Springs, Mechanical Parts, Wires, Etc. Due To Its Smooth Surface, High Strength, And Good Toughness, Annealed Black Silk Has Important Application Value In Various Fields.
High Strength: After Annealing, The Annealed Black Wire Has High Strength And Toughness, And Can Withstand Large Tension And Pressure.
Good Plasticity: Annealed Black Silk Has Good Plasticity, Can Be Bent, Stretched And Other Deformations Within A Certain Range, And Is Suitable For Various Complex Processing Techniques.
Good Corrosion Resistance: After Surface Treatment, The Annealed Black Wire Has Good Corrosion Resistance And Can Be Used In Harsh Environments Such As Humidity, Acid, And Alkali.
Easy To Weld: Annealed Black Wire Has Good Welding Performance, Can Be Welded With Other Metal Materials, And Is Suitable For Various Complex Processing Techniques.
Production Process
Raw Material Preparation: Select Appropriate Metal Materials, Such As Tungsten, Molybdenum, Niobium, Etc., And Mix Them In A Certain Proportion To Prepare Uniform Alloy Powder.
Sintering: The Alloy Powder Is Sintered At a High Temperature To Form A Hard Green Body.
Forging: The Sintered Body Is Forged To Form The Desired Shape And Size.
Heat Treatment: Heat-Treat The Forged Black Silk, Usually By Annealing Process, To Soften It To A Certain Degree And Improve Its Ductility And Machinability.
Drawing: Drawing The Annealed Black Wire To Make Its Diameter And Length Reach The Required Size And Precision.
Cleaning And Packaging: Clean And Pack The Drawn Black Silk To Ensure Its Surface Is Clean And Smooth, And To Prevent Contamination And Damage During Transportation And Use.
