Abstract

DC60 (28/05/40) Tinplate in a tin bath for tin plating containing 40 to 100 g / l Sn ions, preferably 20 to 400 g / l phenol sulfonic acid. L, the relative speed difference between the griddle to be The plating and the quenching solution were set at 2 to 20 m / s until the tinplate product was obtained, plating was done at the most efficient current density over a wide range of at least 80 A / sq. Decimeter, or at The most efficient current density over a wide range of at least 250 A / sq. Decimeter is tin plated in a tin bath for tin plating containing Sn 40 ions to 100 g / l, preferably with phenolic acid. 20 to 400 g / l sulfonic, differential relative speed Between the steel plate to be impregnated and the quenching solution was set at 2 to 20 m / s until a tinplate product was obtained. The plating is done at the most efficient current density in A wide range of at least 80 amperes / sq. Decimeter, or at the most efficient current density in the range. At least 250 amperes / square decimeter
