Low Cost Smelting Raw Material Calcium Silicon Alloy

It is generally produced using either the electrocarbothermal or electrosilicothermal methods. Low-Cost Smelting Raw Material Calcium Silicon Alloy uses silica, lime, and coke as its primary raw materials. These are mixed in specific proportions and placed in an electric furnace at 1500-1800°C in a strongly reducing atmosphere. Under these high temperatures, the raw materials undergo a complex series of chemical reactions. For example, lime (CaO) and silica (SiO₂) first form a calcium silicate slag with a low melting point. Subsequently, a carbonaceous reducing agent (such as coke) undergoes a reduction reaction with the components in the slag, gradually forming a calcium-silicon alloy. During this process, calcium, due to its low boiling point, readily evaporates, producing calcium vapor. SiO₂ is also reduced to SiO₂ (gas). Therefore, the gases discharged from the furnace are primarily CO, Ca (gas), and SiO₂ (gas).

 1. Significant Low Cost: Utilizing the novel carbon-silicon thermal method, this method significantly reduces power consumption compared to traditional production methods.
 2. Excellent Deoxidation Performance: When added to the steelmaking process, the calcium-silicon alloy rapidly reacts with oxygen in the molten steel, significantly reducing the oxygen content and achieving deep deoxidation. This significantly improves the purity of the steel, laying the foundation for the production of high-quality steel.
 3. Effectively Reduces Inclusion Content: This alloy reacts with inclusions such as sulfides and nitrides in the steel to form low-melting-point calcium compounds.
 4. Abundant Resources and Stable Supply: Silicon and calcium, the primary elements that make up calcium-silicon alloys, are extremely widespread in nature and have abundant reserves.
