High Carbon Silicon Granule (3-5mm)

High Carbon Silicon Granule (3-5mm) is made from high-purity silica and coke as raw materials, processed through high-temperature melting, precise crushing, and grading. The particle size is strictly controlled within 3-5mm, resulting in a granular, impurity-free product with excellent flowability. It also offers multiple functions including efficient deoxidation, carbonization, and desulfurization, and can directly replace traditional metallurgical auxiliaries such as ferrosilicon, silicon carbide, and carbonizers. It is widely used in electric arc furnace steelmaking, precision casting, ladle refining, and other applications.

Electric Furnace Steelmaking: As a core deoxidizer and carburizer, it is suitable for induction furnace and electric furnace steelmaking processes. 3-5mm particles melt quickly and react fully, efficiently removing oxygen and sulfur impurities from molten steel, replenishing silicon and carbon elements, controlling the chemical composition of steel, and improving its hardness, toughness, and density. It is suitable for the production of ordinary steel, high-carbon steel, and alloy steel, reducing deoxidizer usage and lowering production costs.

Precision Casting: As an inoculant and carburizer, it is used in the production of cast iron and precision castings. 3-5mm particles are evenly distributed in molten iron, refining grains, improving graphite morphology, enhancing the strength, hardness, and wear resistance of castings, and preventing leakage. It is suitable for the production of high-toughness cast iron, ductile iron, and other precision castings, improving billet quality and reducing scrap rates.

In the ladle refining field: Adapted to ladle refining processes, it can rapidly improve steel purity, stabilize steel composition, reduce billet defects, increase furnace temperature, accelerate refining speed, and improve production efficiency. Suitable for refining mid-to-high-end steel products, it helps companies produce high-quality steel.

In metallurgical auxiliary material processing: It can be used as a raw material to produce other composite metallurgical auxiliary materials, adapting to the personalized needs of various metallurgical processes. It provides diversified auxiliary material solutions for the metallurgical industry, expanding application scenarios and increasing product added value.

Q1: What is the difference between High Carbon Silicon Granules (3-5mm) and other specifications of high carbon silicon granules?

A1: The core difference lies in the particle size and suitable application scenarios. 3-5mm granules are uniform, have good flowability, and a large reaction surface area, making them suitable for induction furnaces, ladle refining, and precision casting. They offer faster reaction speeds, more precise feeding, and reduced waste. 1-3mm granules are more suitable for fine smelting, while 10-50mm granules are more suitable for converters and blast furnaces. The appropriate specification can be selected based on your furnace type and production process.

Q2: Can you provide third-party testing reports?

A2: Yes, each batch of products comes with a testing report from a reputable third-party organization (such as SGS). The testing items are comprehensive, and we can provide reports according to the corresponding testing standards based on your requirements to ensure that the product quality meets your production requirements.

Q3: How do I apply for samples? How long will it take to receive them after application?

A3: You can directly contact our customer service to apply for free samples. Please inform us of your needs (specifications, uses, etc.). We will arrange to send them out within 1-3 business days. Sample shipping costs are negotiable. The sample quality is consistent with the batch products, allowing you to conduct comprehensive testing and trial use, reducing procurement risks.
