SUMMARY:Effect of steelmaking process conditions on cleanliness calcium and non-calcium treated steel in two different secondary refining process route
DESCRIPTION:In the current study, different process conditions with and without Calcium were applied to compare and investigate the steel cleanliness in terms of composition, quantity and size of non-metallic inclusions during refining process and continuous casting. 
The study was conducted in two different production routes and inclusions were characterized through ASTM E45 and SEM/EDS after the steel lamination. It consists to evaluate inclusionary results for heats treated in AHF (Aluminium Heating Furnace – similar CAS-OB) with Ca and RH (Ruhrstahl Heraeus) degasser without Ca on different process parameters such as killing tapping practices, slags addition, sulfur content and homogenization time control in order to have the same castability, properties and application of the final product.
The results showed that for Ca-treat steels in AHF process route, as expected, inclusions were mostly Ca-aluminates globular ones in bigger size than the ones found at RH process from which the best results showed smaller quantity of big inclusions, specially oxides.
