Abstract
La presente invención se refiere a un proceso para la producción de acero donde las inclusiones son generalmente de forma esférica, comprendiendo: A) producir un fundido de acero altamente refinado teniendo un contenido de azufre de no más de 0.005 por ciento en peso, un contenido de oxígeno disuelto de no más de 0.005 por ciento en peso y una temperatura que no excede de 3000 grados F; B) añadir el acero altamente refinado calcio en una cantidad de 3 a 25 veces la cantidad de azufre presente.
