Slab. Conventional and thin slabs with the presence of Ti or Ti+Nb are crack-sensitive due to precipitation of Ti, Nb(C,N) compounds during cooling. [EU-39.] . Prevention can be done by optimization of chemical composition or by modification of cooling strategy. In that case, thanks to the use of an ad-hoc simulator, it was possible to explore and test various cooling patterns. It was found that faster cooling is less detrimental for the analysed steels. For thin slab casting instead improvement of surface quality is attributable also to characterization of the passing to the equalization furnace. The influence of Nb and Ti on surface quality is also faced in another project. In particular, since their preferential precipitation sites at grain edges, in particular at slab off-corner, an innovative soft cooling strategy was implemented [EU-43.] (PRECIPITATION). The temperature of the broad face of thin slab with different widths was kept above 900 °C. The segregation of Nb was mitigated, and improvements in term of transverse crack were achieved, more significantly for smaller thickness. Transversal and star cracks have been investigated in [EU-44.] (DEFREE); quality problems of the slabs were reduced adopting a nickel coating of the mould surface and through identification of the influence of superheat and casting speed. Moreover, significant improvements have been obtained by optimization of the roller settings of the caster in order to better fit the natural shrinkage of steel. This involved a remarkable decrease of centreline segregation severity. [EU-48.] (PMAP) faced the hot ductility induced by Boron content into microalloyed slabs. The influence on precipitation distribution of microalloyed particles of various bending/straightening configurations has been studied the hot ductility of micro-alloyed steel grades is related to the time where precipitation is produced and to the strain rate: both the topics depend on the unbending radius. Unfortunately, during the experimental campaigns carried out during the project no influence of different bending/straightening configurations on precipitation distribution of microalloyed particles has been detected. The observation of segregation phenomena and especially of cracks induced by segregation contributed to the understanding of oscillation xxxx formation [EU-52.] (Determination of high temperature surface crack formation criteria in continuous casting and thin slab casting). The study of distribution pathway le...
