Hydrochloric Acid (HCL)
Hydrochloric acid (HCL) is widely used in pickling lines within cold rolling mills to remove oxide scales from the surface of hot-rolled steel.
This process enhances surface quality, corrosion resistance, and mechanical properties before further processing.
Oxide Scale Removal: Reacts with iron oxides to clean the steel surface.
Surface Preparation: Ensures smooth and defect-free steel for rolling.
Improved Coating Adhesion: Essential for galvanizing and painting applications.
Efficient Pickling Process: Used in continuous and batch pickling lines.
HCL Vapors: Can be emitted during pickling, requiring proper ventilation and treatment.
Acid Regeneration: Some mills use acid recovery systems to minimize waste.
Safety Measures: Operators must follow strict handling protocols to prevent exposure.
