Manufacturers supply ferrosilicon, low ferrosilicon, high carbon ferrosilicon, ferromanganese and other ferroalloy products with favorable prices, and can provide various processing particle sizes such as natural blocks, standard blocks, granules, and powders according to customer requirements.

Product content

Si: 15-20%, Fe: 75-80%, S: 0.02% or less, C: 0.2% or less, P: 0.4% or less, Al2O3: 1.5% or less, MgO: 1.5% or less

Low Ferrosilicon Uses

1. Low ferrosilicon can replace some ferrosilicon alloys by deoxidizing and increasing silicon, increasing iron, effectively controlling the temperature of molten steel, and does not affect the absorption rate of other alloys during use;
2. Low-silicon molten iron can reduce the amount of ore and scrap steel, and ensure the normal heating rate of the molten pool metal, thereby realizing less slag steelmaking, reducing lime consumption and improving metal yield;
