Abstract: A device for galvanically depositing a metal coating on a side of a metal strip includes an anode housing which is connected to a power supply and includes one or more planar, vertical electroplating plates. The metal strip is also connected to the power supply and serves as a cathode, and is supported for vertical movement past the electroplating plate a short distance therefrom and parallel thereto. The electroplating plate includes a generally vertical outlet slot which permits electrolyte to flow out of the anode housing to the region between the electroplating plate and metal strip, and a pump returns the electrolyte to the anode housing. In a preferred embodiment, the outlet slot tapers downwardly and is inclined at a small angle to a vertical reference.

Abstract: The output of coke ovens is increased if the brick constituting the wall between the flues and the coking chamber has a thermal conductivity matched to the rate at which the coke accepts heat. Magnesite has been found to have appropriate thermal conductivity. This material at the lower end of the coking range, namely 1200.degree. C, is impractical due to the fact that it develops cracks and flakes off. However at the higher end of the desired coking range, namely 1300.degree.-1400.degree. C, these difficulties do not appear, and the use of the material leads to increased output of the furnace. More particularly according to the invention firebrick is used which has a thermal conductivity of 2.0-6.0kcal/mh.degree. C and is composed of 20-45% SiC, 23-57% Al.sub.2 O.sub.3 with the remainder consisting of SiO.sub.2 and traces of other oxides.
