1. Product Overview
High Silicon Carbon Alloy is a new type of composite alloy deoxidizer manufactured from raw materials such as silicon metal, silicon carbide, and carbon materials (petroleum coke) through high-temperature smelting or pressing. It combines the strong deoxidation properties of silicon with the long-lasting deoxidation characteristics of carbon.
This product is widely used in the steelmaking and foundry industries as a cost-effective alternative to traditional ferroalloys like Ferro Silicon (FeSi), Silicon Carbide (SiC), and Carburizer. By utilizing the strong exothermic reaction of silicon and the carburizing effect of carbon, it significantly improves the quality of molten steel and reduces production costs.
2. Key Features & Advantages
Strong Deoxidation Capability: The combination of Silicon and Carbon provides a dual deoxidation effect, effectively removing oxygen from molten steel, resulting in a cleaner and more pure final product.
Long-Lasting Effect: The carbon component reacts slowly, extending the deoxidation time and preventing the molten steel from re-oxidation.
Improves Fluidity: Enhances the fluidity of molten iron, which is beneficial for casting complex shapes and improving yield.
Cost Reduction: Replaces expensive traditional alloys like FeSi 75% with a similar effect at a much lower cost, serving as an ideal "cost-saving alloy."
Slag Structure Improvement: Helps in adjusting the composition and fluidity of slag, making it easier to separate from the metal.
