The main requirements of a work roll for cold strip mills are as follows: mechanical resistance to withstand the strains from the rolling process, and wear resistance in order to provide high productivity to the rolling mill and enhance surface quality to the rolled strip.

Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.

Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around to 13mm. How does this work? First, the slabs coming from the continuous caster are pre-sorted in the slab yard.
