Ferroalloy basic purposes: basic classification. Ferroalloy variety, classification method is also more generally classified according to the following methods: Classification by ferroalloy main elements, mainly calcium aluminosilicate silicon alloy plant, manganese, chromium, vanadium, titanium, tungsten, molybdenum and other alloy. Classification according to the carbon content of the alloy, high-carbon, carbon, carbon, calcium aluminosilicate Buy low carbon alloy, ultrafine carbon and other varieties. The main method of ferroalloy production: classification by operating methods and processes. Intermittent smelting. Due to intermittent smelting process is carried out periodically aluminosilicate calcium alloy, which is also called cycle smelting. Given the characteristics of the smelting operation process is different in each period, operating power is also different. Smelting, carbon ferromanganese, medium, low, low carbon ferrochrome and other batch type smelting.
