In the debugging of zinc wire dipping distance, keep the original speed unchanged, according to the time of dipping zinc, the diameter of steel wire, and then estimate the dipping distance. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.
