In these mills, low-thickness bar rolling (< 20 mm) is prone to cobbles, due to several operational reasons, which affects productivity. One major contributor is blockage of slitters and no-twist mill grooves due to excessive chip formation from the rolled bars.

Comparison between the surface defects caused by Al 2 O 3

Feb 12, 2019 · Al2O3 and TiN inclusions in interstitial-free (IF) steel deteriorate the properties of the steel. To decrease the defects of cold-rolled sheet, it is important to clearly distinguish between the degrees of damage caused by these two inclusions on the surface quality of the steel. In this study, a nanoindenter was used to test the mechanical properties of the inclusions, and the distribution Control of TiN precipitation behavior in titanium Although TiN precipitates play a major role in high titanium steels, the high content of Ti and N elements will lead to the precipitation of large-sized TiN, thus losing the effect of grain refinement [14,15]. In addition, the precipitation of a large number of fine carbides and nitrides in the steel will also cause the brittleness of the slab.

Defects / Imperfections in Welds - Slag Inclusions - TWI

The composition of the flux coating also plays an important role in the risk of slag inclusions through its effect on the weld bead shape and the ease with which the slag can be removed. A weld pool with low oxygen content will have a high surface tension producing a convex weld bead with poor parent metal Defects Introduced into Metals During Fabrication and Inclusion defects can potentially be encountered in any metal casting process and may have deleterious effects on the material. The formation of films along grain boundaries can result in low ductility at hot working temperatures. In bearings, high levels of inclusions may spall off in-service resulting in poor performance of the bearing and
