Advantages of ferrosilicon particles:
(1) Homogeneous composition, slight segregation;
(2) Uniform particle size, no fine powder, stable inoculation effect;
(3) Stronger inoculation effect than ordinary ferrosilicon, less prone to slag formation;
(4) Extend the service life of the mold and reduce surface defects;
(5) Reduce pinholes, improve the surface quality of cast pipes, and improve the first inspection pass rate;
(6) Eliminate micro-shrinkage and improve the quality of casting processing.
Ferrosilicon particles can be used not only in the steel industry, but also as a widely used metallurgical material in the iron foundry industry. This is mainly due to the fact that ferrosilicon particles can be used by cast iron manufacturers to replace primers and spheroidizers. In the iron industry, the price of silicon particles is much lower than that of steel, and they are easier to melt. Ferrosilicon particles have a uniform inoculant and have a better inoculation effect during casting. They can contribute to sludge precipitation and graphite spheroidization and are essential metallurgical materials for the production of ductile iron.
