STABILISATION OF JET WIPED WIRE

摘要

The surface quality and lustre of galvanised wire produced by the gas jet wiping method and cooled by jets of a cooling fluid may be improved by exposing the wire to a reactive gas atmosphere containing sulphide or chloride radicals after the wire has passed through the gas jet wiping nozzle and before it is contacted by the cooling fluid. The wire is exposed to the reactive gas atmosphere for a sufficient length of time to form a protective surface coating of metal sulphide or chloride.
