AI Technical Summary
Existing technologies struggle to effectively control the surface quality, microstructure consistency, and sheet quality of ultra-wide and thin appliance panels under mainstream process equipment conditions, especially when the width is greater and the thickness is thinner, making it difficult to guarantee deep-drawing performance and corrosion resistance.
By designing and optimizing production processes with specific chemical compositions, including steps such as converter smelting, RH vacuum refining, continuous casting, hot rolling, and cold rolling, the content of chemical elements and the morphology of inclusions are controlled. Pure steel smelting and integrated production technology are adopted, combined with optimized cold rolling processes such as laminar flow cooling, U-shaped coiling, and tension-free finishing, to ensure high surface quality and microstructure properties of steel plates.
It achieves high surface quality, consistent microstructure and properties, and excellent sheet shape for ultra-thin and wide appliance panels, and possesses good deep-drawing performance and corrosion resistance, meeting the comprehensive quality requirements of high-end appliance products.
