Rare earth ferrosilicon-magnesium alloy is a silicon iron alloy with a rare earth content in the range of 4.0%~23.0% and a magnesium content in the range of 7.0%~15.0%.
Rare earth magnesium ferrosilicon alloy refers to the alloy formed by melting ferrosilicon, calcium, magnesium, rare earth, etc. It is a good nodulizer and has strong deoxidation and desulfurization effects. Ferrosilicon, rare earth ores, and metal magnesium are the main raw materials for the production of rare earth magnesium ferrosilicon alloys. The production of rare earth magnesium ferrosilicon alloy is carried out in submerged arc furnace, which consumes a lot of power, and it can also be produced by intermediate frequency furnace.
Rare earth magnesium ferrosilicon alloy refers to the alloy prepared by adding calcium, magnesium and rare earth to ferrosilicon. It is also called magnesium alloy nodulizer. It is added as nodulizer in the production of ductile iron to change flake graphite into spherical graphite. It can significantly improve the strength of cast iron, and at the same time has the functions of degassing, desulfurization and deoxidation. The use in metallurgy and foundry industry is increasing day by day. Among them, magnesium is the main spheroidizing element, which has a direct impact on the spheroidizing effect of graphite.
Rare earth magnesium ferrosilicon alloy is a gray-black solid, which is made of ferrosilicon as raw material, and the ratio of calcium, magnesium and rare earth is adjusted to the optimal range to make it react smoothly. The casting thickness of each grade of rare earth magnesium ferrosilicon alloy does not exceed 100mm; the standard particle size of rare earth magnesium ferrosilicon alloy is 5~25mm and 5~30mm. According to different purposes, customers can specify special granularity, such as: 5-15mm, 3-25mm, 8-40mm, 25-50mm, etc.
Rare earth magnesium ferrosilicon alloy is one of the main raw materials for the iron and steel industry.
1. Nodulizer, vermicular agent and inoculant for cast iron. Rare earth magnesium ferrosilicon alloy, also known as magnesium alloy nodulizer, is a good inoculant with high mechanical strength and strong deoxidation and desulfurization effects.
2. Additives for steelmaking: light rare earth magnesium ferrosilicon alloy used in the production of nodularizers, vermicularizers, and inoculants, and also used as additives and alloying agents in the production of steel and iron. It is used for refining, deoxidation, denaturation, neutralization of harmful impurities with low melting point (Pb, arsenic, etc.), solid solution alloying, formation of new metal compounds, etc. to purify steel.
