Hot dip galvanizing Continuous Annealing Technical Process：

Coil loading-> uncoiling-> cutting-> thickness detection->welding-> degreasing(alkalibrushing->electrolytic cleaning->water rinsing) ->hot air dryer -> entry accumulator -> annealing -> control cooling -> first cooling->over aging-> second cooling ->water quenching->intermediate accumulator->skin pass mill-> tension leveler-> passivation-> exit accumulator->side trimming->the inspection->cutting->recoiling->unloading-> packing
