Abstract

PURPOSE:To prevent sticking of spotlike zinc on both edge parts of the plating inhibiting surface of a steel strip by providing baffle plates that can be controlled of positions according to the width of the steel plate on both side parts of said parts so as to give no influences upon the flames of a flame wiper. CONSTITUTION:Baffle plates 21 are disposed on both sides of a strip 1 to prevent the arrival of the downward jet flow 15' from a jet flow injector 14 at around a zinc bath surface 9. The plates 21 are mounted slidably in the guides 22 mounted to a flame wiper 7, and their positions are changed by rotating a handle 25 so that the plates are disposed on both sides. Then, the jet flow 15' is prevented from turning round to the other sides at both ends of the strip as shown by a dotted line and the spotlike zinc sticking in the edge parts of the nonplated surface of the strip 1 is prevented thoroughly.

In FIG. At this time,
The area near the intersection of the inhibitor-applied surface 10 of the insect trip l and the plating bath surface 9 is heated with a combustion flame 8 by a flame wiper 7, and at the same time, pulling up of the plating zinc is inhibited.
-26991), on the other side in the plating direction 10', a jet fi 15 is formed by the jet flow injection device 14 for controlling the plating weight. Jet stream 15)
A flow is formed in the vertical direction as seen in Figure 1 along IJ knob 1, but the jink at both edges of IJ knob 13) fi15' (see Figure 2) is blocked by both edges. As a result, the temperature at the intersection of the inhibitor coating 11i+10 and the plating bath surface 9 decreases, and dotted zinc deposits occur on the edge portion of the strip 1 facing the inhibitor direction lO. As mentioned above, it was open.
