Abstract

See full text

A continuous galvanizing line having an annealing furnace of an all radiant tube heating type includes a moisture removal device, dew-point meters, outlets through which the atmospheric gas in the furnace is collected and inlets through which the atmospheric gas from which moisture has been removed with the moisture removal device is fed into the furnace, the dew-point meters and the outlets being placed at least at two points which respectively exist on a side wall in the vicinity of the entrance of the annealing furnace and on a side wall in the vicinity of the furnace top or the furnace bottom at a position where a steel sheet has a maximum end-point temperature, the inlets being placed at two points which respectively exist on side walls on the sides opposite to the sides of the two points for the outlets in the height direction of the furnace, making it possible to steadily control the dew-point of the atmospheric gas to be −45° C. or lower and −80° C. or higher throughout the whole area of the annealing furnace.
