How To Purchase High-quality Noduliser Products

(1) The affinity of the noduliser element with elements such as sulphur and oxygen in the molten iron. A strong affinity forms a compound with these elements, which acts as an external core during the solidification of the molten iron, such as rare earth, magnesium and calcium nodulising elements.
(2) The ability of the noduliser element to change the graphite form from flaky to spherical.
(3) The density and boiling point of the noduliser are lower than those of molten iron. The low density allows it to float automatically in molten iron, and the boiling point is lower than the treatment temperature of molten iron. Magnesium can be converted to a gaseous state at this treatment temperature, and it has a self-agitation effect, thereby changing the nodulising effect.
(4) The magnesium oxide content in the noduliser is about 10% of the magnesium content.
(5) The noduliser is dense, without segregation, shrinkage cavities or porosity, and does not powder.
(6) The noduliser has a uniform particle size distribution, no powdery alloy, and preferably more deformed particles at obtuse angles.
(7) The composition of noduliser from different batches fluctuates little.
