摘要

Process for galvanizing a steel strip (1) comprises passing the strip through a coating apparatus (2) and a continuous furnace (4). The strip is heat treated to form a zinc - iron layer depending on a characteristic measured value measured behind the oven. During a deviation of the measured value of the emission radiation or the gray value of the strip in the central region and in the side regions, the furnace efficiency is adapted to the corresponding characteristic values for an optimum alloy state of the surface of the strip. An Independent claim is also included for a device for galvanizing a steel strip.
