Latest Patents

Song is associated with 1 patent, titled “Manufacturing Method for Tinplate.” The invention describes a process for producing tinplate through controlled flattening, electroplating, and passivation.

During flattening, the method uses two stands. The first stand has working rollers with a surface roughness of Ra 1.6–1.7 μm and a rolling force of 5,000–6,000 kN. The second stand uses rollers with a surface roughness of Ra 0.5–0.6 μm and a rolling force of 3,000–4,000 kN.

For electroplating, the disclosed process specifies a tin concentration of 14–19 g/L in the plating solution. During passivation, it specifies a solution temperature of 41–43°C, a pH of 4.4–4.6, a concentration of 16–18 g/L, and an electric charge density of 120–180 C/m. Together, these parameters define key conditions for the tinplate manufacturing process.
