ferro silicon magnesium supplier
Ferro silicon magnesium refers to an alloy formed by melting ferrosilicon, calcium, magnesium, RE, etc. It is a good nodularizing agent with strong deoxidation and desulfurization effects. It is produced in submerged arc furnace or intermediate frequency furnace with ferrosilicon,RE ore and metal magnesium as the main raw materials.
Anyang Huatuo Metallurgy, as a professional ferro silicon magnesium supplier and exporter, has in the production and export of such product for more than 10 years. Rare earth magnesium ferrosilicon alloys are often supplied in two sizes of 5~25mm and 5~30mm. According to different uses, customers can specify special granularity, such as: 5~15mm, 3~25mm, 8~40mm, 25~50mm, etc.
According to the different content of RE and magnesium, the ferro silicon magnesium supplier always provide it in the grade of 1-6 FeSiMg, 3-8 FeSiMg, 5-8 FeSiMg, etc, the 3-8 is the commonly used type in Chinese market, the 1-6 grade is popular in Spain, Russia, etc countries.
In the production of ductile iron, the RE FeSiMg is added as a nodularizing agent, which can change the flake graphite into spheroidal graphite, which can significantly improve the strength of the cast iron, and also has the functions of degassing, desulfurization and deoxidation. Among them, magnesium is the main spheroidizing element, which has a direct influence on the spheroidizing effect of graphite.
Different product and different production craft will need different grade of FeSiMg in the production of ductile cast iron, if have the related requirement can consult us.
