Non metallic inclusions (slags), branch-on through the casting
process, can occur in the steel. If slag is washed into the steel by an irregularity
during the cast, these non metallic inclusions can come to the surface proximity
of the ingot or strand. After rolling the pre-material these inclusions can lead
under unfavorable conditions to damages. Such defects are provable in the transverse
microsection. In this case titanium carbides and oxides are also available besides
the oxide slags.
