We specialize in producing Silicon Barium Alloy, Silicon Aluminium Barium Calcium Alloy, Si-ca Alloy, Si-al-ba Alloy, Silicon Magnesium Inoculant, Ferro Silicon Inoculant, High Magnesium Alloy Lump, Ferro Silicon Briquette, Ferro Silicon, and other Ferro Alloys.
Why Choose Us
Electric Arc Furnace Smelting
The company uses a three-phase electric arc furnace to refine Ferro Silicon. The furnace's temperature control system, combined with automatic charging equipment, ensures stable silicon content control within ±1%, meeting the demands of highly consistent batch orders.
Screening System
Our proprietary crushing and three-stage screening system accurately grades the product into sizes ranging from 0–3mm, 3–10mm, and 10–50mm. This adapts to various uses, such as cored wire and ladle addition, reducing the number of sorting steps required by the purchasing department.
Multi-Factory Coordination Mechanism
Leveraging integrated production lines in Ningxia and Tianjin, we have established a cross-warehouse transfer mechanism for finished products. This allows us to maintain a stable monthly supply of over 5,000 tons, even during plant maintenance or peak season delivery periods.
What is Ferro Silicon
Ferro Silicon is an iron alloy composed of iron and silicon. It is mainly used for deoxidation, alloying and improving the hardness and strength of steel in steel smelting. It is also commonly used in the foundry industry to improve the quality of castings.
Applications
Deoxidizer in Steelmaking
Ferro Silicon is widely used in the deoxidation process of carbon steel and alloy steel. By reacting with oxygen in the molten steel to form stable inclusions, it helps improve the purity of the molten steel and the quality of the finished product.
Alloying Additive
As a source of silicon, Ferro Silicon can be used in structural steel, spring steel, electrical steel, and other grades to enhance hardness, strength, wear resistance, and improve magnetic conductivity.
Cast Iron Spheroidizing Accelerator
In ductile iron production, Ferro Silicon can serve as a spheroidizing agent carrier, promoting graphite spheroidization and enhancing the toughness and microstructure uniformity of the casting.
Reducing Agent and Decarburizer
During high-temperature smelting processes, Ferro Silicon can be used as a reducing agent to help reduce metal elements in oxides and assist in controlling the carbon content in steel.
Auxiliary Material in Nonferrous Metal Smelting
In the smelting of certain nonferrous metal alloys, Ferro Silicon can be used as an auxiliary material to regulate intermetallic reactions and improve the structure and properties of the final alloy.
