How to Control the Size of Ferro Alloys?
Cases
One of our valued new clients in India inquired about low carbon ferrochrome (the specification details are shown in the table). He asked us how to process the particle size of ferrochrome and how to avoid the shape of slender strips (as shown in the picture).
Specification and Size of Ferroalloy the Customer Required
| Cr % | C % | Si % | P % | S % | Size |
| 60 | 0.10 | 1.5 | 0.03 | 0.03 | 10-70mm |
That’s a really good question. This article will introduce the way we control the size of ferro alloys.
Why Process the Ferroalloys into Different Sizes?
Ferroalloy particle size standard plays an important role in ferroalloy production and application. For example, in the casting and steelmaking process, the difference in the size of the ferroalloy will affect the quality and performance of the finished product. When preparing alloy materials, suitable ferroalloy particle size can improve production efficiency and reduce pollutant emission.
In short, the ferroalloy particle size standard is a very important factor in the production and application of ferroalloys. The selection of appropriate standards and testing methods can ensure that the quality and properties of ferroalloys meet the requirements of production and application.
What is the Particle Size of Ferroalloys?
Ferroalloy particle size refers to the size and distribution of ferroalloy particles. According to the application requirements of ferroalloys, different ferroalloy particle size standards are also different. In general, the particle size standards of ferroalloys are classified in the following ways:
1. Classification according to particle size distribution range: ferroalloy particle size standards include coarse particles, medium particles, fine particles, etc.
2. Classification according to particle size distribution: ferroalloy particle size standards include block, powder, granular, etc.
3. According to the main composition and use classification: ferroalloy particle size standards including ferrosilicon, ferromanganese, ferrochrome and so on.
Different types of ferroalloys have different requirements for particle size standards. For example, ferrosilicon generally requires large and evenly distributed particles, and ferromanganese requires small and evenly distributed particles.
The Detection Method of Ferroalloy Size
The detection methods of ferroalloy particle size mainly include the particle counting method, sieve method, and microscope observation method.
1. Particle counting method: count and analyze the number and particle size of ferroalloy particles by counter. The advantages are high speed and high precision, but special instruments and equipment are required.
2. Screening method: Sieving ferroalloy samples with different particle sizes to obtain particles with different particle size ranges. The advantages are simple and cheap, but only some particle data with obvious distribution range can be obtained.
3. Microscope observation method: Use a microscope to observe the particle size and distribution of ferroalloy samples. The advantage is that very fine particle data can be obtained, but requires specialized technology and microscope equipment.
