Title: Improvements in and relating to methods of annealing and coating wire and band-like material such as hoop iron
IPC: C23C2/02
Filed: 1933-07-24
Abstract: 420,458. Coating with metals. KARTENBERG, F., 16, Schulstrasse, Gevelsberg, Germany. July 24, 1933, No. 20809. [Class 82 (ii)] Wire or band-like material to be annealed and coated with metal by dipping in a continuous process is passed through cooling means, situated between the annealing means and the coating bath, which can be adjusted according to the nature of the material and its rate of travel so that the material is cooled down to approximately the temperature of the molten metal. Oxidation of the material is prevented by passing it through a protective layer, such as salt or coke, which extends either continuously from the annealing means to the coating bath, or from the annealing means to the cooling means and from the cooling means to the coating bath. In the form shown in Fig. 1 a wire b passes through an annealing bath a of molten lead, any excess lead being removed by layers d e of fine coke, coal dust &c. into a protective layer of salt f. A vessel g contains cooling liquid such as soldering fluid or water and the wire passes into the cooling liquid under a roller h. Either the vessel g or the roller h is movable vertically so that the time of immersion of the wire may be varied. The wire then passes through a protective layer f <1>, e.g. of salt, and into the bath of molten metal i. The salt f forms a protective layer on the wire which acts as a flux and is not removed by the cooling liquid if soldering fluid is used ; if water is used the wire must be passed through a flux after leaving the cooling bath and before entering the coating bath. In the form shown in Fig. 2 the protective layer consists of a continuous layer of coke f divided transversely by partitions q, pipes p from which cooling fluid may be sprinkled being situated above the compartments formed by the partitions. The floor o on which the layer f rests slopes downward and is provided with apertures for the discharge of excess liquid. The wire passes either above the partitions q or through comb-like clearances therein, the degree of cooling being regulated by the number of pipes brought into use. A chimney k is provided for the escape of gases and vapours. The bath of molten metal, e.g. zinc, need not be heated except by the waste gases from the heating of the annealing means.
