Abstract
Disclosed is a manufacturing method for a tinplate, relating to the technical field of steel plate manufacturing. With regard to the manufacturing method for a tinplate: in the step of flattening a base plate, double stands are used for flattening, a first stand working roller have a surface roughness value Ra of 1.6-1.7 μm and a rolling force of 5000-6000 kN, and a second stand working roller have a surface roughness value Ra of 0.5-0.6 μm and a rolling force of 3000-4000 kN; in the step of electroplating the base plate, an electroplating solution have a Snconcentration of 14-19 g/L; and in the step of passivating the base plate, a passivation solution have a temperature of 41-43° C., a pH value of 4.4-4.6, and a concentration of 16-18 g/L, the passivation electric charge density being 120-180 C/m.
