Ferro silicon slag

Ferro silicon slag is mainly used in steel slag to restrain pig iron and smelting and casting iron, etc., silicon in ferro silicon slag reacts with oxygen in the furnace to generate SiO2 at the same time, releases a large amount of heat, improves the temperature in the furnace, reduces the use of coke, saves a lot of smelting costs, improves smelting output and saves smelting costs, but also increases the fluidity of molten iron, is conducive to slag removal, increases pig iron labels, improves the toughness and machinable cutting ability of cast iron.
