Overview
Silicon Slag, also known as silicon metal slag or silicon dross, is a by-product generated during the smelting of metallic silicon. Rather than being discarded as waste, this material is collected and processed to offer a cost-effective alternative source of silicon. It consists of a mixture of pure silicon and a silicon-iron alloy (silico-ferrite), making it a powerful deoxidizer and alloying addition in various industrial applications. Our hot-selling Silicon Slag is characterized by its high density, low impurity levels, and consistent chemical composition.

Main Applications
Deoxidizer in Steelmaking
Silicon Slag is widely used in the steel manufacturing process as a powerful and economical deoxidizer. The high silicon content effectively removes oxygen from molten steel, preventing blowholes and improving the density and quality of the final steel ingots.
Alloying Agent in Foundries
In iron foundries, particularly in the production of ductile iron and grey iron, silicon slag is used to adjust the silicon composition. It helps improve the fluidity of the molten iron and enhances the mechanical properties of the casting, such as strength and hardness.
Temperature Raising Agent
During the steelmaking process, the oxidation of silicon generates a significant amount of heat. This helps to accelerate the melting of scrap metal and increase the temperature of the molten bath, thereby shortening the production cycle and reducing energy consumption.
Production of Silicon Metal or Alloys
It can be used as a raw material for producing certain low-grade silicon alloys, optimizing resource utilization and reducing production costs.
