Inoculant Fesiba Ferrosilicon (FeSiBa) is used as an effective inoculant to produce high quality castings of gray iron and ductile iron. It can increase the graphitization core, refine and promote the A-type graphite in the grey iron castings and enhance the strength of the ductile iron castings. It can also reduce the tendency of chilling, improve the machinability and the surface hardness of the gray iron castings.
In addition, it can effectively increase the degree of eutectic undercooling, refining the cluster, promoting graphite nucleation, strengthening the pearlite matrix, improving the material properties and significantly improving the casting performance. It can also promote the formation of spherulitic graphite, which greatly enhances the strength of the ductile iron castings.
Compared with other inoculants, FeSiBa is softer, easier to dissolve and absorb, and less gas content. It can be absorbed by molten iron in a much greater quantity than other inoculants, and its anti-decay ability is stronger.
It is more suitable for ductile iron castings with strict requirements on air tightness or leakage, as well as those of fine-grained iron. It can be used to inoculate ductile iron castings in the ladle with long heat preservation time and long pouring time, and can prevent the formation of cracks caused by oxidation or sulfur deposition in the ductile iron.
With its strong deoxidation capacity and desulfurization function, it can be used to treat a variety of steels and other metals and alloys. It can also reduce impurities and gas elements in molten steel, reduce the internal combustion rate, and avoid the formation of smoke.
This product is mainly used for the production of ductile iron castings and other special steels, such as spherulitic steel. It can reduce the sensitivity of wall thickness and the formation of segregations, improve the processing performance, and decrease the concentration stress.
For ductile iron castings, it can make the graphite balls in the ductile iron smaller and rounder, and improve the spheroidization grade. It can also make the spheroidization decline be stopped, the wall thickness sensitivity be reduced, and the organization be uniform.
Compared with other inoculants, it is more suitable for ductile iron castings that are subjected to high pressure. It can be used to inoculate large-sized ductile iron castings, nuclear power, wind power and other castings. It can also be used to inoculate the spherulitic graphite of universal tool castings.
The global market for Foundry Used Inoculant Fesiba Ferrosilicon is estimated to reach US$4.3 Billion by 2020. This market is primarily driven by the increased demand for electrical steel, which uses a considerable amount of silicon and ferrosilicon to improve the conductivity and resistivity of the cast iron.
The global market for Foundry Used Inoculant Ferrosilicon is expected to grow at a CAGR of 2.4% during the forecast period. The United States, China, and Europe are the key regional markets. This growth is mainly attributed to the increasing demands for steel and other aluminum and ferrosilicon products.
