High Purity High Carbon Silicon (Si 70%, C 20%)

High Purity High Carbon Silicon (Si 70%, C 20%) has four major functions: efficient deoxidation, carbon replenishment, alloying, and desulfurization. Silicon reacts rapidly with oxygen in molten steel to form silica slag, which is easy to separate and effectively reduces the oxygen content of molten steel. Carbon replenishes the carbon content of molten steel, improves carbon recovery rate, reduces the use of external carbon enriching agents, and promotes desulfurization reactions, optimizing steel properties. It is suitable for the production needs of various products such as ordinary steel, alloy steel, and castings.

Steelmaking Industry: Suitable for deoxidation and alloying processes in converter and electric arc furnace steelmaking. It acts as a highly efficient deoxidizer, quickly removing harmful oxygen elements from molten steel, reducing defects, and simultaneously replenishing carbon to stabilize the carbon content, improving the hardness, strength, and corrosion resistance of the steel. It is suitable for the production of various steels such as carbon steel, low-alloy steel, and spring steel, and is especially suitable for steelmaking enterprises with high requirements for steel purity.

Foundry Industry: Used in the production of castings such as gray cast iron and ductile iron. It can be used as a deoxidizer, carbon raiser, and exothermic agent to precisely control casting composition, refine grains, improve graphite morphology, enhance casting density and mechanical properties, reduce defects such as porosity and cracks, and improve the fluidity of molten iron, facilitating casting formation and improving surface finish. Suitable for the production of automotive parts, mechanical components, and engineering machinery castings.

Metallurgical Auxiliary Fields: Can be used as an additive for metallurgical furnace charges to increase furnace temperature, stabilize the reaction environment inside the furnace, promote complete metallurgical reactions, and improve the conversion rate of ferroalloys.

Q1: Can your high-purity, high-carbon silicon (70% Si, 20% C) replace ferrosilicon?

A1: Yes, it can directly replace part or all of the ferrosilicon, and it's more cost-effective. This product has both deoxidation and carbonization functions, with a higher deoxidation efficiency than ordinary ferrosilicon. Using it can reduce raw material costs by 15%-30%, while also reducing energy consumption and not affecting steel quality. It is an ideal substitute for ferrosilicon and has been widely used by many steel companies.

Q2: Can you provide the product's test report? Do you support third-party re-inspection?

A2: Yes, we can. Each batch of products comes with a corresponding test report, detailing the product composition, performance, and other parameters. This report is included with the goods. We also support re-inspection by authoritative third-party institutions. If the test results do not meet the agreed standards, we will unconditionally return or exchange the goods and bear the related costs.

Q3: What is the minimum order quantity? Can you customize specifications?

A3: The minimum order quantity is negotiable. We support small-batch purchases (suitable for trial orders), and larger orders can enjoy more favorable pricing. It also supports customization, allowing for fine-tuning of silicon and carbon content, as well as customization of product form, particle size, and packaging to meet the individual needs of different customers.
