である。(Means for solving the problem) In other words, the gist is that in the alloying treatment of zinc-coated steel strip, the plated steel strip is heated by blowing hot exhaust gas and at the same time static pressure is generated. Galvanized steel is characterized by suppressing the vibration of the band and then heating the plated steel band by heat convection to alloy it. In the alloying process of galvanized steel strip and the alloying process of galvanized steel strip, the plated W4 steel is heated by blowing hot exhaust gas at the same time to generate static pressure to suppress the vibration of the galvanized steel strip. Galvanized steel strip is a galvanized steel strip in which the galvanized steel strip is heated and alloyed by convection, and then gas is sprayed onto the galvanized steel strip to cool it and at the same time generate static pressure to suppress the vibration of the galvanized steel strip. This is an alloying treatment method.

A steel strip 1 whose surface has been cleaned in a plating pre-treatment furnace (not shown) is introduced into a hot-dip galvanizing bath 2 to be plated, and then introduced directly above, where gas is injected from a gas injection/zurle 3 to achieve a predetermined adhesion. control the amount,
Next, in a heating furnace 5 comprising a burner 4, heated exhaust gas of 800 to 900° C., such as combustion exhaust gas from a coke oven, is blown onto the plated steel strip 1 to heat it and slightly alloy it.

ｉｌ＋御ができる。At this time, the hot exhaust gas discharge pressure is 100 to ZOOmmAq, and the static pressure is generated to be about 301Aq or more. Jilt,
As shown in FIG. 2, when the spinal pressure is about 301 Aq or more, the vibration width of the plated steel strip becomes about 511II11 or less, and scratches on the plated steel strip can be reliably prevented. In addition, when controlling the amount of plating deposited using a gas wipe, it is possible to reliably prevent the plating surface from forming a serpentine pattern and achieve uniform adhesion of 1lff.
You can control il+.
