Silicon slag is actually produced in the process of producing ferro silicon alloy or silicon metal and other alloys in the electric furnace smelting process. Silicon slag is divided into ferro silicon slag, industrial silicon slag and silicon carbon slag.  The product, index type is different, price and use are also different.  

Accordingly, must distinguish the specific use of product, specific index model, purchase appropriate product.  The content of silicon slag is generally 30, 40, 50, 60. In most cases, many customers are used to replace ferrosilicon in casting to save cost, but also can be used to refine pig iron. The effect is very good, can save a lot of cost, is a product with relatively high economic benefit.  

For example, the silicon content of si slag 50 is about 50%, compared with other traditional ferro alloy products, silicon slag 50 factory price is both economical and affordable, can be used for deoxidation, casting, steelmaking and other industries.  Silicon slag 50 is used in remanufacturing process, which can effectively reduce production cost, strengthen resource recovery, greatly shorten deoxidation time and improve steelmaking efficiency.  

There is also a ferro silicon slag product, which can be used to replace ferro silicon with good effect. It contains pure silicon and iron, and the effect is very good. The silicon content is slightly lower, but the price is much cheaper than ferro silicon, which can replace ferro silicon and save cost. 

 Ferro silicon slag is suitable for cupola, electric furnace, converter.  Strong ability of deoxidation and desulfurization, effectively improve the fluidity of molten steel, purify molten steel, reduce impurities in steel, reduce steelmaking costs, improve economic benefits.
