Ferrosilicon can increase the temperature of molten steel during the steelmaking process.
This operation has several significant benefits
Promote the dissolution of alloy elements: High temperature helps to increase the solubility of alloy elements (such as chromium, nickel, etc.), making these alloy elements more evenly distributed in molten steel, improving the performance and quality of alloy steel.
Improve fluidity and pourability: High-temperature molten steel has lower viscosity and surface tension, which makes the molten steel easier to flow and pour, which is beneficial to obtaining more uniform and stable castings.
Reduce solidification shrinkage cavities and shrinkage porosity: High temperature helps to reduce the solidification shrinkage of molten steel during the solidification process, thereby reducing the risk of shrinkage cavities and shrinkage porosity in castings and improving the integrity and density of castings.
Reduce energy consumption: To a certain extent, increasing the temperature of molten steel can reduce subsequent reheating energy consumption and save energy costs.
In short, by increasing the temperature of molten steel, the solubility of alloy elements can be improved during the steelmaking process, the fluidity and pourability of molten steel can be optimized, the occurrence of casting defects can be reduced, energy can be saved, and production efficiency and product quality can be improved.
