Ferrosilicone Alloy 72

Ferrosilicon 72 is used as an inoculant and spheroidizing agent in the cast iron industry. Adding a certain amount of ferrosilicon to pig iron can prevent the formation of carbides in iron and promote precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent in ductile iron production.

Do you know the precautions when smelting ferrosilicon 72?

Raw material selection: choose raw materials of stable quality and composition according to the requirements, control the content of impurities in silica, especially Al2O3, MgO, SiO2 content in silica 97% or more CaO, and other harmful impurities. At the same time, the quality of coke used for smelting should also be strictly controlled, with high fixed carbon content and less impurities introduced by ash.

Dosing and mixing: According to the specifications of the ferrosilicon to be produced, calculate the mixing proportion and mix the raw materials in sufficient quantity so that the composition is homogeneous. In this way, the silicon recovery rate can be increased and the product quality can be improved.

Melting process: reasonably control the melting temperature and melting time, so that the iron and silicon are fully reacted. Temperature and time are important factors affecting the silicon content of ferrosilicon, too high or too low temperature, too long or too short time will affect the quality of the product. Therefore, in order to meet the requirements of silicon content and product composition, it is necessary to choose suitable melting process parameters.

Equipment maintenance: Check and maintain the melting equipment regularly. The quality of the equipment directly affects the quality and yield of the product, so it is necessary to regularly maintain and repair the equipment to ensure its stability and reliability.

Chemical Analysis: Ferrosilicon is regularly chemically analyzed to control its composition and quality. To guarantee the quality of the products, problems in the products can be detected in time by chemical analysis, and the production process can be adjusted according to the analysis results.
