High Carbon Silicon (Silicon Carbon Alloy) - Product Overview

High Carbon Silicon is an innovative, cost-effective alloy widely used in converter and electric furnace steelmaking. It serves as a high-performance substitute for traditional metallurgical materials like ferrosilicon, silicon carbide, and recarburizers, streamlining the refining, deoxidizing, and alloying processes.

Product Composition

As the name implies, High Carbon Silicon's primary components are Silicon (Si) and Carbon (C). Its typical chemical composition is as follows:

Silicon (Si): 65% - 68%

Carbon (C): ~20% or higher

Other: Includes trace amounts of SiO₂, H₂O, and other elements.

Physical Specifications

Form: Lumps

Standard Size: 10mm - 50mm

Note: Custom sizes can be manufactured to meet specific customer requirements.

Primary Application

High Carbon Silicon is primarily used for diffusion deoxidation in the smelting of carbon steel. Its unique composition allows it to perform multiple functions simultaneously.

Key Characteristics & Advantages

High Efficiency Deoxidizer: Possesses excellent silicon activity, leading to a short deoxidation time and high deoxidation efficiency.

Dual-Functionality: Unlike pure ferrosilicon, its high carbon content allows it to both deoxidize and recarburize the molten steel in a single step.

Cost-Effective: Significantly cheaper than using separate additions of ferrosilicon and recarburizers, improving the comprehensive economic benefit of the electric furnace.

Operational Simplicity: Easy to use, which saves energy and simplifies the steelmaking process.

Environmental & Workplace Benefits: Helps in reducing environmental pollution and improves working conditions for operators.

Economic Benefit

By replacing the combined use of ferrosilicon and recarburizers, High Carbon Silicon enhances the overall efficiency and profitability of steel production, offering a superior cost-to-performance ratio.
