Payback calculations
The payback calculation of the Zinc Coating Control System is always an local estimation of factors. Calculation itself is straight forward procedure.
Compared to manual control the zinc saving can be expected to be some 5-7 %.
Compared to an outdated control system the savings might be some 3-4 %.
Following is an sample calculation:
Zinc:
Production = 300.000 ton/a
Average thickness = 1.1 mm
Average width = 1.2 m
Average coating = 137 g/m2/side
Zinc price = 2200 $/ton
Base material price = 800 $/ton
Base material scrap price = 300 $/ton
Zinc saving = 4 %
Area = 2 x 300.000 ton/a / 0.0011 m / 7.86 ton/m3 = 69.000.000 m2/a
Zinc saving = 4 % x 137 g/m2 x 69.000.000 m2/a = 380 ton/a
Saving when the coils are sold by area = 380 ton/a x 2200 $/ton = 840.000 $/a
Saving when the coils are sold by weight = 380 ton/a x (2200 - 800) $/ton = 530.000 $/a
Base material:
50 coils/d
coating thickness change coils 20 %
scrap saving in product change 15 m
Base material saving = 48 w/a x 7 d/w x 50 coils/d x 20 % x 15 m x 0.0011 m x 1.2 m x 7.86 ton/m3 = 520 ton/a
Base material saving = 520 ton/a x (800 - 300) $/ton = 260.000 $/a
Additional benefits:
better line utilization
better strip uniformity
operator can concentrate on the quality

Delivery options
The Zinc Coating Control System can be delivered directly to the end customer or as in many cases the air knife or coating gauge supplier integrates it into his electronics and bundles it to the overall delivery. This advanced ad on product gives a nice edge for the equipment suppliers business.
