Ferro Silicon 70 (FeSi 70) is a ferroalloy containing approximately 70% silicon and 30% iron. Produced by smelting quartz, steel scrap, and coke in an electric arc furnace, this grade of ferrosilicon offers an economical balance between performance and cost. Ferro Silicon 70 is widely used in steelmaking and foundry operations, especially in applications that demand reliable deoxidation and alloying at a lower price point.
Ferro Silicon 70 Product Specifications
FeSi70 is typically supplied in various forms, including lump, granular, and powder, with common specifications as follows:
FeSi70 Lump: 10-50mm, 50-100mm
FeSi70 Granular: 0-3mm, 3-10mm
FeSi70 Powder:<0.3mm
FeSi70 Distinguishing Features from FeSi72 and FeSi75
Silicon Content: FeSi70 has a silicon content of around 70%, which is lower than FeSi72 (72% silicon) and FeSi75 (75% silicon). This difference in silicon content makes FeSi70 more suitable for applications where slightly lower silicon levels are preferred.
Cost Efficiency: Due to its lower silicon content, FeSi70 is often more cost-effective compared to FeSi72 and FeSi75, making it an economical choice for certain industrial processes.
Advantages of ferrosilicon 70
1. Balanced Silicon Content (≥70%): Provides effective deoxidizing and alloying performance while optimizing overall cost.
2. Economical Choice: Lower silicon content offers a more affordable alternative to FeSi 75 or FeSi 72, ideal for price-sensitive applications.
3. Uniform Quality: Produced under strict quality control to ensure stable chemical composition and consistent results.
4. Versatile Product Forms: Available in standard lumps, granules, powders, and natural blocks for flexible application.
5. Improves Process Efficiency: Enhances steel cleanliness and reduces slag formation in steelmaking processes.
Ferrosilicon 70 uses
Steelmaking: Serves as a deoxidizer and alloying element in the production of structural steel, carbon steel, and low-alloy steel.
Cast Iron Industry: Functions as an inoculant to promote uniform graphite formation and improve mechanical properties.
Magnesium Smelting: Acts as a reducing agent in the Pidgeon process for producing metallic magnesium.
Electrode Manufacturing: Used in welding rod coatings to enhance arc stability and reduce oxidation.
Production of Silicon-Based Alloys: Used in combination with other elements to produce specialized alloys for industrial use.
