Ferro Silicon 75

Ferrosilicon 75 refers to FeSiAl1.5-A (commonly known as 75A, 75# ferro silicon), which is a high-silicon ferrosilicon with a silicon content of about 75%. When producing ferrosilicon 75, like ferrosilicon 72, it is also necessary to use silica and coke as raw materials and smelt in a submerged arc furnace. Different from the production of ferrosilicon 72, it is necessary to control the appropriate raw material ratio and operating conditions during the smelting process to ensure that ferrosilicon with high silicon content is obtained. In addition, to improve the purity and stability of ferrosilicon, appropriate amounts of auxiliary agents, such as oxidants, alloying elements, etc., are sometimes added.

The main uses of ferrosilicon 75 are as deoxidizer and alloying agent in the steelmaking industry and as inoculant and spheroidizing agent in the cast iron industry.

Specifically, ferrosilicon 75 can effectively remove oxygen from molten steel and improve the purity and quality of steel. At the same time, it can also be used as an alloying element additive to improve the properties of steel.

In addition, ferrosilicon 75 is also used as a reducing agent in ferroalloy production and has applications in other aspects.

1. Steel industry: ferrosilicone 75 is an indispensable deoxidizer in the steelmaking industry, which can ensure the quality of steel and reduce steel's phosphorus and sulfur content.

2. Foundry industry: Adding an appropriate amount of ferrosilicone 75 to the molten iron can prevent the iron from forming carbides, promote the precipitation and spheroidization of graphite, and act as an inoculant and spheroidizing agent.

3. Magnesium metal manufacturing industry: Ferrosilicone 75 is often used in the high-temperature smelting process of magnesium metal in Pidgeon magnesium smelting to replace the magnesium in Cao.Mgo.
