Mainly refers to the destruction of such elements and hinder the graphite ball elements, according to their mechanism of action can be divided roughly into three categories:
First, the ball-type anti-consuming elements, such as sulfur, oxygen, selenium, tellurium, etc., are magnesium, rare earth elements form compound, by consuming the ball elements to prevent the formation of spheroidal graphite.

The second is the realm of segregation ball interfering elements, including tin, antimony, arsenic, copper, boron, titanium, aluminum, etc. These elements enriched to grain boundaries, prompting the late carbon eutectic crystallization, the formation of abnormal dendritic graphite If higher levels of these elements can also contribute to the eutectic graphite medium distortion, to form a slug or a thick flake graphite.

Third, some intermediate ball interfering elements, such as aluminum, bismuth, they lower content starring role through segregation distortion contributed graphite, with higher levels of energy consumption when the ball elements.
