Production Processes and Strengthening Mechanisms
Production Processes
Smelting
Utilizes oxygen top-blown converters or electric arc furnaces to control impurity levels (P ≤ 0.035%, S ≤ 0.035%).
Rolling
Employs thermo-mechanical controlled processing (TMCP) to refine grain structures, thereby enhancing strength and toughness.
Heat Treatment
Normalizing is required for some steel grades (e.g., thick plates), while quenching and tempering are used for high-strength engineering machinery steels.
Strengthening Mechanisms
Fine-Grain Strengthening
Alloying elements (e.g., Nb, Ti) inhibit grain growth during processing. Smaller grain sizes increase the density of grain boundaries, which hinder dislocation movement and improve strength (e.g., precipitation of niobium/titanium carbonitrides).
