This production line is cold rolling steel strip continuous annealing galvanizing production line, functions including annealing, restoration, galvanizing, straightening, passivating, etc.
This galvanizing line adopts “L” annealing furnace layout. Cold rolled steel strips enter the annealing furnace for annealing and restoration, and then enter zinc pot for hot dip galvanizing in airtight conditions, during which the thickness of zinc coating are controlled by air knife and after cooling exported to be the final galvanized steel strips. Quality of the zinc coating surface and mechanism performance and glancing flatness of the steel strips are improved via wet temper gauge & leveler and straightener, and the passivation is realized during the post-process. Finally the ready galvanized steel coils come out.
This production line mainly includes:
Decoiling section
Welder + crescent shear
Entry horizontal accumulator
Restoration purposed annealing furnace
Zinc pot
Air knife system
Cooling system after galvanization
Online zinc coating thickness Gauge(optional)
Skin pass
Stretching bending straightener
Passivation process section
Exit vertical accumulator
