Abstract: A seawater corrosion-resistant marine engineering steel and a preparation method thereof are provided. The seawater corrosion-resistant marine engineering steel consists of the following chemical compositions in percentage by mass: C: 0.011-0.069%, Si: 0.11-0.29%, Cr: 1.51-1.99%, Nb: 0.02-0.05%, Zr: 0.01-0.02%, RE: 0.0034-0.02%, and the balance of Fe and inevitable impurities. The mass percentages of Zr element and RE element also satisfy the following formulas: 0.01%<Zr+RE<0.02%, and Zr/RE=1-3. The marine engineering steel is designed with cheap chemical compositions of low carbon, low silicon and medium chromium, and is completely free of valuable corrosion-resistant metal elements such as Ni and Cu.

Abstract: A method and device for separating and recovering heavy metal ions through membrane-forming mineralization fixation, applicable in the domain of acid wastewater treatment containing heavy metal ions. The process involves mixing composite mineral particles with heavy metal acidic wastewater, then conducting a first hydration reaction under static conditions. This leads to adsorption, precipitation, and crystallization of heavy metal ions in the wastewater via a colloidal liquid membrane, resulting in particles coated with a mineralized membrane. These particles exhibit a gap between the mineralized membrane and their core. The next step is to separate these coated particles and recover them. The preparation of composite mineral particles involves mixing sodium carbonate/sodium silicate, bentonite, carbide slag, and water, followed by a second hydration reaction and subsequent granulation, aging, and dehydration condensation. The particle sizes of both bentonite and carbide slag are maintained at ?74 m.
