Ferroalloy uses: alloy called for deoxygenation deoxidizer. Steel of various elements on the bonding strength of the oxygen compound deoxidizer, namely oxygen capacity, from weak to strong in the following order: chromium, manganese, carbon, silicon, vanadium, titanium, boron, aluminum, zirconium, calcium. Thus Deoxidants price, usually steel deoxidation commonly used is made of silicon, manganese, aluminum, calcium, iron alloy composition. Development Trend of ferroalloy production technology: ferroalloy products structural changes occur, varieties for diversity. Overall trends can be described as: increasing the variety and take advantage of alloying elements; rational use of resources Deoxidants plant, product development direction to the composite; reduce harmful impurities in the alloy composition, the pure of direction; shorten the process, reduce energy consumption, improve production efficiency, thereby reducing the cost of production and consumption.
