第3図に示すストリツプ7への金属蒸気付着部
(ダクト6の開口部)において、蒸気もれは非常
に少ないので、式(1)の熱バランス式が成り立つ。 Since there is very little steam leakage at the part where the metal vapor is attached to the strip 7 (the opening of the duct 6) shown in FIG. 3, the heat balance equation (1) holds true.
γs×υ×d×w×Cs×(Ts out

In addition,
In formula (1), the unit of adhesion amount is expressed in Kg/ m2 ,
To express the film thickness (mm) like the signal from a coating amount detector, divide it by the specific weight of the metal.
式(1)を書き直せば式(2)を得る。 If we rewrite equation (1), we get equation (2).

きる。Qd = [γs × d × Cs × (Ts out - Ts in)] / H (2) In other words, if the plate thickness d and the strip temperatures Ts in and Ts out at the inlet a and outlet b of the metal vapor deposition area are known, The adhesion amount Qd can be obtained using equation (2).
The strip temperature sensor is installed at the inlet a and outlet b of the attachment part.
However, it is much cheaper than one adhesion amount detector and provides sufficient accuracy.

If we rewrite equation (3) as equation (2), we get equation (4)
is obtained.
