Improvement of formability of continuously organic coated coils by controlling ageing behaviour of low carbon steel substrates

Objective

The aim of this project is to define low C steels and process conditions to manufacture continuous "COIL COATED" coils free from coil breaks (fluting) and stretcher strains after cold forming. The objective is to be achieved by exploring the possibility of using hot coils rolled in the austenitic and ferritic field with different chemical compositions. The effect of the chemical composition, hot rolling conditions both in the austenitic and in the ferritic phase, total thickness reduction during cold rolling, annealing cycle in the hot-dip zinc coating and continuous annealing lines, the repartition of pre- deformation between skinpass and stretch levelling in the galvanising or continuous annealing line on recrystallised ferrite grain size, yield point elongation and strain ageing index will be investigated. Also the response to pickling and the sensitivity of strip edges to crack appearance will be assessed.
