A Mathematical Model for the Prediction of the Scale Layer Formation on ASTM A510/A853 Cold-Drawn Hypoeutectoid Steel Wire After Batch Annealing

Annealed hypoeutectoid ASTM A510/A853 steel wire is widely used in the construction industry due to its mechanical properties, which makes it a very versatile material work with. This concerns prediction of thickness scale layer once subjected batch annealing process. We propose mathematical model approach oxidation occurring during The treats this phenomenon as non-isothermic instance; takes input heating curve, cooling and holding time that corresponds cycles cycle. assume temperature outer spiral segments furnace atmosphere temperature. With aid model, possible predict oxide spirals annealed drawn coils after with reasonable accuracy. did not find visible evidence decarburization; steels study do decarburize. As an approximation, we assumed outside equals atmosphere.
