FeSiMg (Nodulizer)
Ferro silicon magnesiumalloy is composed of silicon, calcium, magnesium, rare earth by remelting, it is an
excellent nodulizer with strong effect of deoxidation and desulfurization.
Nodulizer with magnesium content4%, 5%, 5.5%, and RE between 1% to 2%, is usually used in medium frequency
furnace production and low sulfur iron water process. It has an advantage of mild nodulizing reaction and elements
easy to absorb. Magnesium content of 6% 7% are medium magnesium nodulizer, usually used in cupola and
electric furnace duplex smelting, or smelting of pearlite ductile iron castings in medium frequency furnace.
Determining appropriate nodulizing agent addition amount according to the thickness of casting part and the
sulphur content of iron water, which has wide application andbroad nodulizing process. Series of high magnesium
nodulizer, suitable for cupola, iron water of sulphur content 0.06%-0.09%, addition amount is between 1.6%-2.0%.
Low aluminium nodulizer is used to produce casting parts easily to have pinhole defect and the casting having
aluminum content requirements in the molten iron. Pure Ce&La nodulizer has pure molten iron, round graphite ball.
