In present world clean steel has important role. Because of its good ductility and formability it is widely used in numerous applications. For making this special type of steel one should take care of inclusions present in steel. Formation of nonmetallic inclusion has severe effect on properties of steel. Non metallic inclusion comes out during rolling hence they are unwanted. If inclusions are intimately distributed in steel then it can be count under tolerance limit. But inclusions formed by reoxidation has size more than 100 micro m. Reoxidation in steel occurred due to huge availability of oxygen from atmosphere. That result in formation of large size inclusion in killed steel
