Ferroalloy basic purposes: pure metal additives steelmaking aluminum, titanium, nickel and silicon metal, metal manganese, chromium and the like. Some easily reducible oxides such as MoO, NiO, also used in place of ferroalloys. In addition steelmaking Deoxidants, there nitride alloys, such as nitrided ferrochrome, ferromanganese, etc., and mixed with heating agent heat iron alloy. The main method of ferroalloy production: classification by operating methods and processes. Intermittent smelting. Intermittent concentrate smelting charge is added to the smelting process or batch furnace. Generally divided into two periods of melting and refining steel Deoxidants Hebei, in the melting of the electrode is buried in the charge; and refining of steel-making electric arc Henan Deoxidants plant exposure, and refining of EAF is exposed refining is completed, alloy and slag discharge, and then proceed to the next load of new material melting furnace.
