摘要： A device according to the invention comprises trolleys arranged above a plating bath and movable in transverse directions of a steel strip, guide rollers secured to lower ends of vertical levers depending from the trolleys and in contact with edges of the strip by urging means such as counter weights acting upon the vertical levers, and shielding plates secured to the lower ends of the vertical levers below the guide rollers so as to shield undersides of the strip in the proximity of the edges from anodes immersed in the plating bath in opposition to the strip.The device according to the invention can maintain the positional relation between the edges of the strip and shielding plates notwithstanding staggering movements of the strip to prevent the edges of the strip from being excessively plated.

摘要： Improved recovery of tin from sludge formed during a halogen-type electrolytic tinplating of steel sheet comprises leaching the sludge with water at a pH of 7 or less, separating an iron-containing sludge remaining after the leaching, alkalifying the filtrate obtained in the first separation step to deposit tin-containing sludge, separating and recovering the tin-containing sludge deposited in the first alkalifying step, redissolving the tin-containing sludge in an alkaline solution, and electrolytic reduction of the alkaline solution. High purity metallic tin is recovered from sludge, at a high yield. Other materials are also recovered for reuse from the filtrate and precipitation, which are formed during the process, without pollution of the operational environment.
摘要翻译：在钢板的卤素型电解镀锡过程中形成的污泥中锡的回收率提高包括用pH为7以下的水浸渍污泥，分离浸出后剩余的含铁污泥，碱化第一次分离中得到的滤液分离和回收沉积在第一碱化步骤中的含锡污泥，再次溶解在碱性溶液中的含锡污泥，以及碱性溶液的电解还原。高纯度金属锡以高产率从污泥中回收。还可以回收其他材料，以便在过程中形成的滤液和沉淀物再次使用，而不会污染操作环境。

摘要： An apparatus for plating a metal strip in an electrolytic cell is provided with a supporting roll. The support roll is disposed apart from the deflector rolls by a predetermined distance and supports the metal strip in such a way that the catenary of the metal strip can be reduced. The distance is determined so that the catenary is 0.04 or less times of the distance between upper and lower electrodes in the electrolytic cell. When the metal strip is a steel plate having a density of 7.85.times.10.sup.-6 (kg/mm.sup.3), the predetermined distance l (mm) between the axis of the deflector roll and that of the supporting roll is subject to the following formula: ##EQU1## in which the distance between the upper and lower electrodes is .DELTA.D (mm), the thickness of the metal strip being t (mm), the width thereof being W (mm) and the tension applied to the metal strip being T (kg).
