Introduction to Ferro silicon

Ferrosilicon is an ferro alloy composed of iron and silicon. Ferrosilicon is an ferro silicon alloy made by smelting coke, steel shavings, quartz (or silica) as raw materials in an electric furnace. Due to the easy synthesis of silicon and oxygen into silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, due to the large amount of heat released during the generation of SiO2, deoxidation is also beneficial for increasing the temperature of molten steel. Meanwhile, ferrosilicon can also serve as an alloying element additive and is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry.

Classification of Ferro Silicon

Classified according to smelting method.

Ferrosilicon can be divided into high silicon ferrosilicon (GG), ordinary ferrosilicon (PG), low aluminum ferrosilicon (DL) and high purity ferrosilicon (GC).

Classified according to physical form.

Ferrosilicon can be divided into ferrosilicon lumps, ferrosilicon briquettes, ferrosilicon powder and ferrosilicon granules.

Classified according to composition.

There are different brands of ferrosilicon, such as 75 ferrosilicon, 72 ferrosilicon, 65 ferrosilicon, etc. These different brands of ferrosilicon contain different proportions of silicon and iron.

Classified according to silicon content and iron content.

Ferrosilicon can be divided into different grades such as low ferrosilicon, medium ferrosilicon, and high ferrosilicon.

How to distinguish the advantages and disadvantages of ferrosilicon alloy

1. Observe the appearance quality

The appearance of high-quality ferrosilicon alloy should be dark gray, with a smooth surface, no cracks and no oxidation. The appearance of inferior ferrosilicon alloy may have problems such as uneven color, rough surface, and many cracks. Therefore, by observing the appearance quality of ferrosilicon alloy, we can initially judge its quality.

2. Check ingredient content

The composition content of ferrosilicon alloy is a key factor affecting its quality. The silicon content of high-quality ferrosilicon alloys should comply with national standards and have low impurity content. You can check the product label or consult the manufacturer to understand the ingredient content, or you can detect it through professional chemical analysis methods. If the component content does not meet the standards, it means that the quality of the ferrosilicon alloy is poor.

3. Physical performance testing

High-quality ferrosilicon alloy should have good hardness and toughness and not be easily broken. The physical properties of the sample can be checked by observing and tapping it. If the sample is brittle or lacks toughness, the ferrosilicon alloy is of poor quality.

What are the effects of inferior ferrosilicon alloys?

1. Affect product quality

The high impurity content in inferior ferrosilicon alloys will lead to insufficient strength, hardness and toughness of the steel, affecting the quality and service life of the product. At the same time, the silicon content in inferior ferrosilicon alloys may also be insufficient, resulting in substandard silicon content in steel, further affecting product quality.

2. The production process is unstable

Inferior ferrosilicon alloys are prone to cracks, fragmentation and other problems during the production process, bringing instability to the production process. These problems may lead to reduced production efficiency, increased production costs, and may even cause safety accidents.

3. Impact on the environment

The production process of inferior ferrosilicon alloys may produce a large amount of waste gas, waste water and other pollutants, causing pollution to the environment. At the same time, inferior ferrosilicon alloys are also prone to produce debris, dust and other waste during use, further exacerbating environmental pollution problems.

Common “pitfalls” in the ferrosilicon procurement process

Inferior products

Some suppliers may sell inferior products or reduce costs by adulterating them with other low-value materials. Purchasers need to carefully inspect product quality to avoid purchasing products that do not meet requirements.

The price is artificially high

Some suppliers may intentionally raise prices, causing buyers to pay unnecessary costs. Buyers need to conduct market research to understand the reasonable price range in order to get better prices during the procurement process.

Contract fraud

Some unscrupulous suppliers may take advantage of contract loopholes to commit fraud, such as making false promises, failing to meet delivery deadlines, etc. Purchasers need to carefully review the terms of the contract and understand the supplier's reputation and operating conditions to avoid losses.

Technical barriers

Some suppliers may keep product technical parameters, production processes, etc. confidential or restrict disclosure, making it difficult for purchasers to obtain comprehensive product information and accurate technical support. Purchasers need to establish a good communication mechanism with suppliers to understand the technical requirements and specifications of products.

Lack of after-sales service

Some informal channel suppliers often lack a complete after-sales service system. When buyers encounter product quality problems or use difficulties, it is difficult to obtain timely and effective technical support and solutions. Therefore, the purchaser needs to choose a supplier with good after-sales service and sign a formal purchase contract with them to clarify the after-sales service terms.

Some suggestions for ferrosilicon purchasing:

Determine purchasing needs
First of all, it is necessary to clarify the purchased ferrosilicon specifications, quality requirements, quantity, delivery time and other requirements in order to select the appropriate supplier.

Understand market conditions
Understand the market price and supply and demand situation of ferrosilicon in order to formulate reasonable purchasing plans and budgets.

Choose the right supplier
Based on procurement needs, select suppliers with strength and good reputation and establish long-term cooperative relationships with them to ensure the stability of ferrosilicon quality and delivery time.

Sign a contract
After selecting a supplier, it is necessary to sign a formal procurement contract with them to clarify the rights and obligations of both parties and ensure the legality and standardization of the procurement process.

Pay attention to delivery time and quality
During the procurement process, it is necessary to pay attention to the delivery time and quality of the supplier to ensure that ferrosilicon is delivered on time and with high quality. If there are quality problems, they should be resolved through consultation with the supplier in a timely manner.

Create purchasing files
In order to facilitate management and traceability, it is recommended to establish a complete procurement file, including procurement contracts, quality inspection reports, delivery documents, etc.
