VAI pickling for ultra thin hot strip in ACB

摘要

In 2000 ACB (Aceria Compacta de Bizkaia, Bilbao, Arcelor) decided to double the capacity of the thin slab caster and of the hot mill by increasing the yearly production from 100, 0000 to 180, 0000 t/y. To cover a larger market for the additional tonnage a new pickling line had to be installed. As the upstream plant can roll ultra thin hot strip, the objective is that the pickling line should be able to process thin gauges and to supply the market with strip similar to cold strip.
