1.High quality with competitive price. 2. strong production capacity 3.Timely delivery 4.Safe package

       One useful by-product of the production processes is silica fume, which is later added to concrete mixes to improve compressive and bonding strength . A large portion of the global Ferro Silicon supply is manufactured in China, USA and India. The most basic definition of the Ferro Silicon production process would be that the silica (or sand) is mixed with coke, and then a reduction process takes place in the presence of millscale, scrap or another source of iron. A blast furnace is employed for Ferro Silicon production, but for larger contents of silica, an electric arc furnace is used.
