摘要： PURPOSE:To improve the solderability and corrosion resistance of an iron plated steel plate by electrolytically tinning the steel plate and subjecting the tinned plate to a reflow treatment. CONSTITUTION:A steel plate is plated with iron to make the surface of the steel plate close to pure iron. This iron preplated steel plate is electrolytically tinned and heat treated by a conduction or induction heating method. The pure iron and tin are subjected to a reflow treatment under contacting state to form a sound iron-tin alloy layer. Thus, the corrosion resistance is improved, and the solderability is not deteriorated by the alloy and shows a favorable value.

摘要： PURPOSE:To produce a titled steel plate having a good one side plated surface and a uniform and smooth non-plated surface by introducing a steel strip applied with a shield film on the non-plating surface into a hermetic structure of a non-oxidative or reducing atmosphere and subjecting the same to one side plating. CONSTITUTION:A steel strip 5 applied with degreasing, reducing and annealing treatment is introduced into a snout 4. In a turn roll 6 section, gaseous O2 or steam is blown from the spray nozzle 11 of a shield film imparting means 10 to the non- plating surface of the strip 5 to form a shield film of 10-1,000Angstrom thicknesses. Thence, this is introduced into a seal box 3 of the hermetic structure maintained in a non-oxidative or reducing atmosphere, where it is guided onto a molten metal bath surface by guide rolls 7, 7'; at the same time part of molten metal 2 is flowed and built up via a flow through 9 by an electromagentic pump 8, whereby it is touched and stuck to the one side of the strip 5, after which the plating metal stuck on the surface to be plated is wiped away with a wiping nozzle 9', whereby it is controlled to a desired coating weight.

The plate is then treated with cathodizing in aqueous solution contg. chromate, bichromate or its mixture, and contg. 5g/l or less of SO4 concentration, at pH 3 or more, and at temperature 50 deg.C or more. Next, the plate is surface-treated with high temperature water of 65-100 deg.C for 0.3-10sec. The process removes SO4 , F , or other anions from the chromate layer, reduces Cr to Cr , and removes the remaining Cr .
