Above temperature, typically the temperature more than fusing point under the normal pressure of hot-dip aluminum bath 1.
The case where bath temperature of hot-dip aluminum bath 1 is adjusted to 20 DEG C higher than the fusing point of the hot-dip aluminum bath 1 or more of temperature
Under, though from the front end 12a of nozzle 12 spray non-active gas temperature be room temperature (such as 0 DEG C or more room temperature) if can
It accesses and is nearly free from the thin part of thickness of plating overlay film, in the hot-dip aluminizing steel wire 3 of surface almost non-cohesive aluminium block.Cause
This, never heats the non-active gas sprayed from the front end 12a of nozzle 12 and obtains being nearly free from plating overlay film
The thin part of thickness, from the perspective of the almost hot-dip aluminizing steel wire 3 of non-cohesive aluminium block of surface, the bath temperature of hot-dip aluminum bath 1
Lower limiting value be preferably regulated as the temperature of high 20 DEG C of fusing point or more than hot-dip aluminizing bath 1, be more preferably adjusted to compare hot-dip aluminizing
The temperature of high 25 DEG C of the fusing point of bath 1 or more.
From the viewpoint of improving the thermal efficiency, the upper limit value of the bath temperature of hot-dip aluminum bath 1 is preferably 800 DEG C or less, more excellent
It is selected as 780 DEG C or less, further preferably 750 DEG C or less.
In addition, being not easy to adhere to aluminium from the part that efficiently manufacture does not allow the thickness for being also easy to produce plating overlay film thin, on surface
From the perspective of the hot-dip aluminizing steel wire 3 of block, the bath temperature of hot-dip aluminum bath 1 is preferably 650~750 DEG C.
It should be noted that the bath temperature of hot-dip aluminum bath 1 is that temperature sensor is impregnated in apart from hot-dip aluminum bath 1
The value when position of bath face depth about 300mm will be measured near the steel wire 2 that hot-dip aluminum bath 1 lifts, the temperature
Sensor is made of thermocouple is inserted into the protection pipe for protecting thermocouple.
In the present invention, it is not easy from the part that efficiently manufacture does not allow the thickness for being also easy to produce plating overlay film thin, on surface
Adhere to from the perspective of the hot-dip aluminizing steel wire 3 of aluminium block, preferably before so that steel wire 2 is impregnated in hot-dip aluminum bath 1, keeps steel wire 2 logical
