Alumina And Its Role In Iron And Steelmaking Ispatguru

Alumina And Its Role In Iron And Steelmaking Ispatguru

Sep 08, 2017018332Alumina inclusions deteriorate the properties of steel. Alumina is solid at steelmaking temperature and is brittle in nature. On rolling, alumina inclusions break up which is a serious surface defect. The alumina may accumulate in the continuous casting nole causing clogging of the nole. This affects the steel flow rate to the mould.
