Ferro Silicon Magnesium Alloy

Applications: Ferro Silicon Magnesium alloy is used to produce Nodulizer, vermicularizer and inoculation. It is also used as additive and alloying constituent to make iron and steel.

Properties: This product is a kind of alloy that we add Calcium, Magnesium and Rare-earth to Ferrosilicon and also called as Magnesium alloy Nodulizer which is a good kind of Nodulizer. Its mechanical strength is high. It also has good desulfurization and deoxidization effects.

1. Production technology:

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. Ferrosilicon and Ce-La mish metal, or rare earth silicon and magnesium is the main raw materials of FeSiMgalloy. The production of FeSiMgis performed in submerged arc furnace, medium frequency furnace can also be used.

2. Product application:

Nodulizer with magnesium content4%5%5.5%, and REbetween 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.after nodulizing process.

3. Size and packing:

FeSiMg alloy is gray solid, with ferrosilicon as raw material, and adjust the proportioning of calcium-magnesium-rare earth into the best range, so it reacts smoothly. Rare earth-mg-SI-Fe alloy grades the thickness does not exceed 100mm; rare earth-mg-SI-Fe alloy standard size is 10-30mm, and15-30mm in two ways. According to different purposes, customers can specify a particular size, such as:1-4mm, 1-5mm, 5-15mm, 3-25mm, 8-40mm, 25-50mm , also in accordance with user requirements.
