FeSiMgRe alloy refers to an alloy prepared by adding calcium, magnesium and rare earth to ferrosilicon.
It is also called magnesium alloy spheroidizing agent.
It is added as a spheroidizing agent in the production of ductile iron to turn flake graphite into spherical graphite.
It can significantly improve the strength of cast iron and has the functions of degassing, desulfurization and deoxidation.
Its use in the metallurgical and foundry industries is increasing.
Among them, magnesium is the main spheroidizing element and has a direct impact on the spheroidizing effect of graphite.
