摘要： PURPOSE:To prevent the treatment liquid from being diluted with the cleaning liquid by cleaning the metallic strip above wringer rolls to squeeze the treatment liquid from the surface treated metallic strip, and preventing the cleaning liquid from being mixed with the treatment liquid. CONSTITUTION:After the treatment liquid is squeezed from a metallic strip 1 which is surface treated in a vertical treatment tank 2 by a pair of wringer rolls 5, 5' above the tank surface. and the metallic strip is washed by spraying the cleaning liquid from spray headers 6, 6', and the cleaning liquid is stored at the upper part of the wringer rolls 5, 5'. The washing liquid flowing down along the surface of the wringer rolls 5, 5' by the rotation of the wringer rolls 5, 5' is wiped by elastic liquid removing plates 8, 8' which are continuously arranged over the whole width direction of the rolls, and collected in a cleaning liquid collecting pan 9. The cleaning liquid flowing down from both end parts of the wringer rolls 5, 5' is received by shaft end part liquid receivers 10, 10' provided to the lower part of the respective end parts and flows into the washing liquid collecting pan 9. This constitution prevents the cleaning liquid of the metallic strip 1 from being mixed with the treatment liquid.

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.

摘要： PURPOSE:To surely prevent warpage deformation without flawing a strip in continuous plating of molten metal onto this strip. CONSTITUTION:A sink roll 4, a lower support roll 5 and an upper support roll 6 are arrayed in order of the traveling pass of the strip 3 with the sink roll 4 in the lowermost position in a plating cell 1. The sink roll 4 is formed shiftably in a horizontal direction and the lower support roll 5 is formed shiftably in horizontal and vertical directions. The press-in quantity of the lower support roll 5 is optimized by changing the positional relation in the vertical direction in association with the positional relation in the horizontal direction between the sink roll 4 and the lower support roll 5, by which the warpage deformation is corrected to zero. Simultaneously, the generation of the pressing flaws and slip flaws on the strip 3 by the lower support roll 5 is obviated.

摘要： PROBLEM TO BE SOLVED: To improve the adhesion property of a plating metal and a metallic strip by an anodic treatment prior to a plating treatment at the time of electroplating the metal on the metallic strip subjected to the activation treatment by degreasing, washing and pickling. SOLUTION: The metallic strip S previously subjected to degreasing and washing is subjected to the activation of the surfaces by the pickling treatment and is washed again. At the time of transporting the metallic strip S by means of rolls 2a, 2, 2b and electroplating the metal on the surfaces by passing the strip in a plating cell 1, the metallic strip S is first passed through an inlet side pass section 8 and is subjected to the anodic treatment by supplying the current between the strip as an anode and an electrode 3 as a cathode, by which the surfaces of the metallic strip S are reactivated. In succession, the metallic strip S is passed through an outlet side pass section 9 and the metal is electroplated on the surfaces of the metallic strip S by supplying the current between the roll 2b as the cathode and the electrode 3 facing the roll as the anode. The plating layers having the excellent adhesion property to the metallic strip are thus obtd.
