摘要： The present invention relates to a vertical type stream plating apparatus for plating the surface of a metal strip (1) with tin, chromium, copper or the like. Fundamentally, the apparatus comprises an electrolyte feeding nozzle for feeding an electrolyte into a space between electrodes, a side seal provided on both sides in the widthwise direction of the electrode and a pressure equalizing chamber (18) provided on the backside of the electrode (17). The apparatus further comprises a electrode having a plurality of through holes communicating with the pressure equalizing chamber provided in an electrode box, waste electrolyte equipment provided with a waste electrolyte box for gathering and discharging the electrolyte and a seal equipment provided at the lowermost portion of the apparatus for preventing the outflow of the electrolyte. The above constitution enables the flow rate distribution of the electrolyte in the widthwise direction of the strip to be made more homogeneous than the prior art and enables the flow rate of the electrolyte to be increased without causing problems of vibration (fluttering phenomenon) of the strip and adsorption of the strip to the electrode, which contributes to an increase in the speed of plating and an improvement in the quality of plating.

摘要： PURPOSE:To prevent a strip from being vibrated or fluttered by providing a liq. discharge box at the upper part of a vertical tank, surrounding the strip with a partition wall pierced with many holes in the box and discharging the liq. through the hole. CONSTITUTION:A strip 1 is vertically supported by a deflector roll and introduced into a vertical tank. The liq. is discharged fro a liq. discharge box 2 provided at the upper part of the tank by the ascending flow velocity. A partiton wall 5 is provided in the box 2 to surround the strip 1. The ascending liq. flow is passed through the many holes 5-1 formed in the partiton wall 5, converted little by little to the horizontal flow and discharged into the outer liq. discharge box 2. The partiton wall 5 also acts as a breakwater, and the vibration of the strip 1 caused by the liq. current is reduced.

摘要： PURPOSE:To make the device integral and compact by disposing a settling chamber above a dissolving chamber, disposing a filter in the treating liquid outlet of the upper part of this settling chamber and connecting a metal introducing pipe to the lower part of the settling chamber. CONSTITUTION:This metal ion dissolving device is formed of ' a vertically long integral cylindrical structure provided with the settling chamber 2 in the upper part of the dissolving chamber 1. A filter unit 9 and the final treating liquid outlet 13 are disposed in an overflow section 7 of the settling chamber 2. The treating liquid is replenished from a circulating tank through a treating liquid supply port 12 into a treating liquid replenishing chamber 6 in the lower part of the device. The treating liquid is supplied through a perforated plate 4 into the dissolving chamber 1. Metallic particles/pieces are replenished from a charging port 16 existing upper than an overflow 7 bath surface by a metallic particle/piece introducing pipe 3 into the dissolving chamber 1 without disturbing the flow of the settling chamber 2. The dissolving chamber 1 stores the metallic particles/pieces and allows the treating liquid rising from the lower side to pass through these particles/pieces, thereby dissolving the metallic particles/ pieces as metal ions into the treating liquid.
