Abstract
Steel wire coils are used as semi-finished products for the production of fastener billets. The process usually requires preliminarily drawing wire coil to reduce the diameter of products. The drawn wire usually has to be annealed to improve the cold formability. In the fastener industry, most companies use a subcritical process for spheroidized annealing. The quality of spheroidize annealed steel wire affects the forming quality of screws. Various parameters affect the quality of spheroidized annealing such as spheroidized annealing temperature, prolonged heating time, furnace cooling time and flow rate of nitrogen. The effects of spheroidized annealing parameters affect the quality characteristics of wires, such as tensile strength and hardness. In this study, a series of experimental tests are carried out and Taguchi method is used to obtain optimum spheroidized annealing conditions to improve the mechanical properties of two AISI 1022 low carbon steel wires, WA and WB. It is revealed experimentally that, for wire WA, spheroidized annealing temperature and prolonged heating time are the significant factors; however, for wire WB, spheroidized annealing temperature and furnace cooling time are the significant factors to influence the mechanical properties of steel wires.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
