High grade grinding ball steel is developed by Electric Furnace,refining and billet caster.The chemical composition is strictly controlled by narrow band,and the carbon segregation index is strictly controlled.The results show that the transverse section section shows that the crack is at a certain angle with the outer edge of the steel and has a certain depth,but the end is smooth and without sharp angle,it is judged as a folding defect.
