Ferroalloy basic purposes: ferro-alloys variety. By production methods Classification: new blast furnace iron alloy, calcium aluminosilicate alloy prices, ferroalloy furnace, calcium aluminosilicate new alloy production plant, furnace extrajudicial (metal calorimetry) ferroalloy, iron alloy vacuum solid state reduction, electrolysis ferroalloy, calcium aluminosilicate new alloy, in addition There are compact oxide and ferro-alloys and other special alloy heat. Ferroalloy is comprised of one or more kinds of metal or metalloid elements consisting of iron and alloy steel and as a deoxidizer, desulfurizer and alloy additives such as foundry industry. For example Ferrosilicon is an alloy of silicon and iron; ferromanganese alloy of manganese and iron; calcium alloy is an alloy consisting of silicon and calcium. On production methods and purposes, ferroalloy also include low iron alloy metal manganese, chromium, vanadium and industrial silicon.
