Nodulant

Nodulant refers to an alloy formed by melting ferrosilicon, calcium, magnesium, rare earth, etc. It is a good spheroidizing agent and has strong deoxidation and desulfurization effects. Ferrosilicon, rare earth ores and metallic magnesium are the main raw materials for the production of nodulant. The production of nodulant is carried out in submerged arc furnaces, which consumes a lot of power. Intermediate frequency furnaces can also be used.

Nodulant 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.

Nodulant is a gray-black solid. It is made from ferrosilicon as raw material, and the mixing ratio of calcium, magnesium and rare earth is adjusted to the optimal range to make it react smoothly. The casting thickness of each brand of nodulant does not exceed 100mm; the standard particle size of nodulant is 5~25mm and 5~30mm. According to different uses, customers can specify special particle sizes, such as: 5~15mm, 3~25mm, 8~40mm, 25~50mm, etc.
