Hot Dip Galvanizing Line

A Vietnamese steel manufacture were investing in a new green-field plant, which included a Hot Dip Galvanizing Line (HDGL) and a Colour Coating Line (CCL). Iconsys were successful in winning the contract for the electrical equipment for the Hot Dip Galvanizing Line.

The line consisted of an entry section with two uncoiler paths to the four strand horizontal accumulator, a process section with a horizontal furnace with carry-over rolls to support the strip. The hot strip then progressed through the furnace exit snout into the molten zinc.  The exit of the zinc was provided with an air knife with controlled airflow to remove excess zinc before passing through the cooling section to a skin pass mill, then through a leveller, a coater for anti-fingerprint laquer and into the vertical exit accumulator.
