New silicon barium calcium alloy is composed of one or two or more metals or non-metallic 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 the production method and use in terms of new silicon barium calcium plant, ferroalloy also include low iron alloy metal manganese, chromium, vanadium and industrial silicon. Ferroalloy industry has experienced three periods: the blast furnace and electric large-scale development period. The new high-quality silicon barium calcium many new varieties, such as high-grade ferrosilicon, calcium silicon alloy, tungsten iron, molybdenum iron, low carbon ferromanganese and ferrochrome came into being. These varieties can not be produced in a blast furnace, so the development of electric technology. Especially with the implementation of long-distance transmission, a large number of electric technology developed.
