Ferroalloy production technology development trend: Over the past twenty years, with the progress and development of the steel industry and science and technology, industrial production variety world ferroalloy smelting process, technology and equipment, energy saving, environmental protection, energy and resource recovery We have a rapid development and comprehensive utilization of breakthrough technologies. Ferroalloys purposes: for casting inoculant nuclei. One of the measures to improve the performance of cast iron and steel casting solidification conditions change. To change the solidification of high quality Si-Ba-Ca alloy, typically added before pouring some ferroalloys as nuclei Si-Ba-Ca alloy prices, grain center formed Si-Ba-Ca alloy, graphite becomes finely divided form, grains refining, improving performance of the casting.
