Abstract
To improve the pickling efficiency of oxide scales formed on hot-rolled 45# steel, this study investigates the influence of oxide-scale microstructure on pickling behavior by employing a series of representative oxide scales generated under simulated coiling conditions. The results demonstrate that oxide scales formed under different coiling parameters exhibit pronounced differences in layered structure, phase constitution, and interfacial characteristics, which in turn lead to significant variations in pickling efficiency. In particular, the presence of continuous metallic Fe layers and eutectoid structures within the oxide scale markedly impedes the pickling process, whereas oxide scales dominated by FeO are more readily removed, thereby facilitating more efficient pickling.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
