Features of 72% Ferrosilicon

High Silicon Content

With a silicon content of up to 72%, this alloy exhibits unique physical and chemical properties beneficial for metallurgical processes.

Strong Reducibility

Due to the high reducibility of silicon, 72% ferrosilicon is often used as a reducing agent in smelting operations.

Versatile Applications

72% ferrosilicon is widely utilized in steelmaking, casting, and welding, acting as a deoxidizer, inoculant, and alloy additive.

Applications of 72% Ferrosilicon

Casting

Functions as an inoculant, enhancing the internal structure, strength, and toughness of castings.

Steelmaking

Used as a deoxidizer, it effectively removes oxygen from steel, improving its quality and performance.

Welding

Acts as an additive in welding materials, improving the strength and durability of welded joints.

Production Methods of 72% Ferrosilicon

The manufacturing of 72% ferrosilicon is carried out through traditional smelting and new smelting methods:

Traditional Smelting Method

Uses silica, steel scraps, and carbon-based reducing agents such as metallurgical coke, gas coke, semi-coke, lignite, or anthracite.
The materials are smelted in a submerged arc furnace to produce ferrosilicon.
New Smelting Method

Designed to produce ferrosilicon powder at lower costs, reducing or eliminating the need for metallurgical coke and steel scraps.
Primary raw materials include ferrosilicon coke and silica, with optimized raw material ratios to enhance product quality and reduce production costs.
