Application of ferrosilicon (1) Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain qualified steel and ensure the quality of st...

Smelting ferrosilicon with Coke as a reducing agent, so that more easily carbon self-baking electrode, the use of coke brick masonry out of the iron mouth and flow iron groove, sometimes with graphite powder coated ingot mold, the use of carbon sample spoon to take liquid samples and so on. In short, smelting ferrosilicon reacts from the furnace to the iron, pouring process, the opportunity to contact with carbon is obviously a lot.

Some components of ferrosilicon, sometimes due to storage during the water or air humidity is too large, at the same time, aluminum, calcium and phosphorus impurity content is high, after a certain period of time, will produce powder phenomenon, and then release smelly, toxic phosphine ﹙PH3﹚ and hydrogen ﹙ASH3﹚ gas, serious and even may occur combustion phenomenon. Improper content of aluminum, phosphorus and calcium in Ferrosilicon will contribute to the ﹙ of ferrosilicon powder as shown in figure I ﹚. When the content of aluminum and phosphorus increases to a certain value at the same time,

Smelting ferrosilicon generally adopts mine heat furnace, which is produced by continuous operation method. The so-called continuous operation method, is that with the furnace after experiencing high temperature, continuous reaction and melting, so that the surface of the material down accordingly, while constantly adding new furnace, the furnace furnace is always in full condition. It is released periodically according to the amount of alloy accumulated in the furnace.

Ferroalloy used in iron and steel metallurgy and foundry industry, with the modern industry for the variety of steel varieties requirements, ferroalloy varieties are also expanding, with the development of modern materials technology.

Graphite powder excellent conductivity and anti-electromagnetic interference ability makes it in the electronic confrontation war outburst, in addition, its high temperature resistance, antioxidant and other properties in the aviation field has also been widely used, thus affecting the graphite powder ferroalloy market price.
