Ferrosilicon is used as an inoculant and nodularizer in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and much better shock resistance than steel. In particular, ductile iron, its mechanical properties are at or close to those of steel. The ferrosilicon particle inoculant is formed by breaking the ferrosilicon into a certain proportion of small pieces and filtering through a certain number of sieves. The high-quality ferrosilicon inoculant has a uniform particle size and a

Silica is a factor that affects the quality of ferrosilicon 65: the raw material of ferrosilicon 65 is silica, and good silica has the characteristics of silica impurity content and uniform particle size, but must pay attention to the particle size of silica. Coke also plays a vital role in the quality of ferrosilicon 65: coke also plays a vital role in the production of ferrosilicon 65, and it is easy to produce good ferrosilicon 65 when choosing good cokes.

Ferrosilicon 72 and 75 generally refer to the difference in silicon content, our 72 generally has a silicon content of 72-80, 75# ferrosilicon refers to a silicon content greater than or equal to 75, and there are 75A, 75B, 75C ferrosilicon, 72# The ferrosilicon refers to the content of silicon greater than or equal to 72, such as 75 ferrosilicon and 72 ferrosilicon, both of which are national standard grades, in addition to non-standard ferrosilicon, such as 65 ferrosilicon, and other trace elements The content of aluminum in 75A# ferrosilicon is below 1.5, the content of 72 ferrosilicon is b

Ferrosilicon is used as an inoculant and nodularizer in the cast iron industry. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent. .

Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted by quartz and coke in an electric heating furnace. The content of the main component silicon is about 98% (in recent years, the silicon content of 99.99% is also included in metal silicon), and the remaining impurities are iron and aluminum. , calcium, etc.

The main function of 45 ferrosilicon is deoxidation and alloying. If the content is too small, the deoxidation of the weld metal will be insufficient; if the content is too large, the strength of the weld metal will be too high, and at the same time, the low temperature impact toughness of the weld metal will be reduced.
