SUMMARY:Enhanced control technologies of hot rolling in an endless line
DESCRIPTION: We introduce and discuss two technical features of hot rolling in an endless line with the excellent application results. The first feature is functionality to establish rolling stability with high quality of products in endless rolling. The second feature is automation to enable multiple rolling modes. In an endless line, continuous caster and rolling equipment are directly connected via a tunnel furnace. There is a shear between caster and tunnel furnace. The line can be operated in 3 modes – “endless“, “semi-endless“ and “coil to coil“ rolling. With endless rolling, there is no shear cut between caster and tunnel furnace. The advantage of endless rolling is that ultra-thin coils can be produced stably with high product quality since, unlike a conventional hot rolling, there is no loss of tension at head/tail end. With semi-endless rolling, the caster output is cut into long slabs. The coiler entry shear is used to create several coils from a single slab. With coil to coil rolling, the caster output is cut into slabs. The mill and caster can operate at different speeds in semi-endless and coil to coil rolling. When rolling speed needs to be changed to satisfy production or operational requirements, coil to coil or semi-endless rolling can be selected. The multiple rolling modes feature provides flexible selection of rolling mode on a single line and expands both product types and operational flexibility. Finally, we show excellent control results in the actual line with the above technical features.
