ELECTROPLATING SOLUTION CONCENTRATION

Steel sheet is tinned by leading it through a series of tanks containing electrolyte. The tin electrolyte concentration in the last tank is important for the surface quality of the product.

Concentration measurement of tin in the electroplating solution

A concentration of tin which is too high causes deposits on the roller, leading to indentations in the surface of the steel sheet. Tin concentration that is too low leads to voids and imperfections in the product surface.
